Consider stainless steel for your outdoor kitchen because it's sleek and easy to find.

        The popularity of stainless steel outdoor kitchens is due to their low cost and high durability. Stainless is also easy to clean because it's not porous like stone and wood. And finding the right stainless steel appliance or accessory is easy.

Outdoor Kitchen Designs for Ideas and Inspiration

The benefits of stainless are almost endless. Stainless has a sleek, reflective appearance that will pick up the colors in its environment. It also looks great next to stacked stone, stucco, concrete, and tile. If you decide you want to change the look of your space, stainless will transition with you.

Stainless is great for the outdoors because it's weather resistant. It won't warp in heat or humidity like wood and won't rust in wet weather. Some stainless steel cabinetry and accessories offer extra protection against the elements with weather-tight rain drawer gutters and sealed cabinets and doors.

Your local home store will have a lot of selection in stainless steel. Also check out specialty outdoor retailers for individual components like insulated drawers for everything from ice to trash cans. If you can imagine it in stainless, it's probably out there and your neighborhood home store may be able to order items they don't keep in stock, as well.

There are some parts of kitchens that seem synonymous with stainless, like appliances and sinks, but some parts of your outdoor kitchen may not seem like they lend themselves to stainless. Countertops, cabinetry and even barstools made from stainless steel are actually great options.

If you're working with a smaller area or want to add an island to an existing outdoor kitchen, stainless prep stations are easy to find at restaurant supply stores. They're lightweight and portable so you can take them with you if you move. Cabinets made from stainless are easy to keep clean and beautiful. Their interiors also reflect some light so you'll have additional visibility in otherwise dark corners.

You may think it's unnecessary to mention that nearly every appliance comes finished in stainless steel, but there are a few outdoor options you may want to consider that aren't found in typical indoor kitchens.

Bar items are great in stainless steel and ice drawers are a nice addition for outdoor drink service. Speaking of drawers, a large stainless warming drawer is helpful when grilling or for warming buns and rolls. Also check out stainless utensils, serving ware, bar tools and fixtures to complete

Gain insight on stainless steel kitchen cabinets, an alternative material used in modern kitchen design.

    Stainless steel is a material prominent in most modern kitchens designs. Homeowners seeking an updated kitchen often desire stainless steel appliances and sinks, and stainless steel kitchen cabinets work well with this look.

Historically used in restaurants, laboratories and for medical storage, stainless steel cabinetry has moved beyond its industrial beginnings and is now found in high-end home kitchen designs.

While you can get a very sleek, angular look with stainless steel kitchen cabinets, it does show fingerprints and scratches easily so you want to make sure you are comfortable with a non-perfect surface if your kitchen is used frequently. Fortunately, over-the-counter stainless steel cleaners are readily available so that fingerprints can be easily wiped away.

Besides being easy to clean, stainless steel is a durable and sanitary material—two very appealing characteristics for a frequently used room such as a kitchen. For the earth-friendly homeowner, stainless steel cabinets are considered a green product, meaning they are recyclable, non-toxic and easy to clean without the use of harsh chemicals. Additionally, steel cabinets are a great pick for outdoor kitchens, since they hold up quite well against the elements.

stainless steel is everywhere in the kitchen

Stainless steel is a more expensive material than wood. One option to achieve the look of stainless steel while avoiding the cost is to install wood or particleboard cabinets covered in metal door and drawer fronts.

Stainless steel kitchens may seem cold and institutional to some. Pairing stainless steel cabinets with warmer materials such as wooden flooring, glass inserts, or even a kitchen island made of a warmer wood can be more appealing to the eye and provide a unique feel to your kitchen design. 

combination of stainless steel & wood makes your kitchen classical but mordern

Copper or bronze hardware or accents can also break up all of the silver tones that stainless steel kitchen cabinets provide. Whether you are seeking a truly sleek modern space or a more transitional look, using steel as an alternative to wood in your kitchen cabinetry can give a breath of fresh air to your home.

Stainless steel is not a single alloy, but rather the name applies to a group of iron-based alloys containing a minimum of 10.5% chromium. Other elements are added and the chromium content increased to improve the corrosion resistance and heat-resisting properties, enhance mechanical properties, and / or improve fabricating characteristics. There are over 50 stainless-steel grades that were originally recognized by the American Iron and Steel Institute (AISI.) Three general classifications are used to identify stainless steel. Among alloy types, “304” is the basic chromium-nickel austenitic stainless steel and has been found suitable for a wide range of applications. It is the most readily available in a variety of product forms. This grade is easy to form and fabricate with excellent resistance to corrosion. It is a nonmagnetic steel.

The stainless alloy resists most oxidizing acids and can withstand all ordinary rusting. However, it will tarnish. It is immune to sterilizing solutions, most of the organic chemicals and a wide variety of inorganic chemicals.

Stainless steel is used for critical environments that require a higher level of resistance to corrosion than Type 304 can offer.  Type 316 is also austenitic, non-magnetic, and thermally non-hardenable stainless steel like Type 304. The carbon content is held to 0.08% maximum, while the nickel content is increased slightly. What distinguishes Type 316 from Type 304 is the addition of molybdenum up to a maximum of 3%. Molybdenum increases the corrosion resistance of this chromium-nickel alloy to withstand attack by many industrial chemicals and solvents, plus inhibits pitting caused by chlorides. Molybdenum is one of the single most useful alloying additives in the fight against corrosion.

By virtue of the molybdenum addition, Type 316 can withstand corrosive attack by sodium and calcium brines, hypochlorite solutions, phosphoric acid; and sulfurous acids used in the paper pulp industry. This alloy, therefore, is specified for equipment in the medical industry, pharmaceutical manufacturing, and sterile area. Type 316 is also used extensively for surgical implants.

430: Stainless steel is a low-carbon plain chromium ferritic stainless steel. Mainly used for kitchen grade tables and utensils along with other applications not demanding in anti-corrosion properties. However, the stainless steel has good corrosion resistance in mildly corrosive environments and good resistance to oxidation at elevated temperatures. The steel has limited weldability and should not be used in the as welded condition for dynamic or impact loaded structures. Being a ferritic material, 430 is liable to brittle fracture at sub-zero temperatures, and cannot be used in cryogenic applications. As the steel does not contain nickel or molybdenum, it is less expensive than any of the 300 series.

430 is a simple corrosion and heat-resisting grade and finds application in areas where mildly corrosive conditions occur or where scaling resistance at moderate temperatures is required. Typical applications include: Automotive trim, kitchen utensils, sinks, washing machine parts and industrial pipe and tube. Heat resisting applications up to 759oC.

Differences between Type 430 and Type 304:430 grade stainless steel is magnetic,
304 is non-magnetic
430 is somewhat difficult to form, 304 is easier to form and weld
430 is made up of 17% chromium and 0.12% carbon, 304 contains 18% chromium and 0.08% carbon

Differences between Type 304 and Type 316:Both types 304 and 316 are easily welded and formed
Both types are non magnetic
304 is made up of 18% chromium, 316 contains 17% chromium
304 contains no trace of molybdenum, 316 contains 2.1% molybdenum
The biggest difference between the grades is molybdenum is added to Type 316 to increase corrosion and pitting resistance.

When Stainless Steel is chosen for its resistance to corrosion it is important to use the correct type or grade. Since stainless steel is an alloy of iron when the metal does corrode it is in the form of rust. There is also “Pitting Corrosion” which is usually caused by acid chloride. Chloride reacts with chromium to form chromium chloride. Chromium is removed from the stainless steel leaving only iron. As the chromium is dissolved chlorides bore into the stainless creating a smooth wall pit. The probability of pitting will occur with higher temperatures, higher chloride content and the lower the pH. Under the right condition of the three stated factors, Type 304 stainless steel bucket could pit through in less than 8 hours. When molybdenum is added to the stainless steel the pitting corrosion resistance improves.

Another type of corrosion is “Crevice Corrosion”. In sharp corners or overlapping surfaces the passive film on stainless steel can break down. The crevice needs to be large enough for the corrosive solution to penetrate and small enough where the solution remains stagnant.

Stainless steel equipment can be made out of all three types of stainless steel: 316, 304 or 430. Choose the correct grade of stainless steel to meet the environment and application.

Type 304 is the most widely used austenitic stainless steel.

Also known as '18-8' stainless because of its composition, which includes 18 percent chromium and 8 percent nickel, 304 stainless steel has good forming and welding properties, as well as strong corrosion resistance and strength.

Type 304 stainless steel also has good drawability, can be formed into a variety of shapes and, in contrast to type 302 stainless, can be used without annealing.

Uses:

Common uses for type 304 stainless steel include in the food industry; for brewing, milk processing, wine making, as well as in pipelines, yeast pans, fermentation vats and storage tanks.

Due to its ability to withstand corrosion by various chemicals found in fruits, meats and milk, 304 grade stainless is also found in sinks, tabletops, coffee pots, refrigerators, stoves and various other utensils and cooking appliances. Other areas of use include in architecture, chemical containers, heat exchangers, mining equipment, and in marine nuts, bolts and screws.

Type 304L:

Type 304L stainless steel is an extra-low carbon version of the 304 steel alloy.

The lower carbon content in 304L minimizes deleterious carbide precipitation as a result of welding. Consequently, 304L can be used 'as welded' in severe corrosion environments and eliminates the need for annealing. However, this grade has slightly lower mechanical properties than the standard 304 grade.

304 Stainless Physical Properties:

• Density: 0.803g/cm3
• Electrical resistivity: 72 microhm-cm (20C)
• Specific Heat: 0.50 kJ/kg-K (0-100°C)
• Thermal conductivity: 16.2 W/m-k (100°C)
• Modulus of Elasticity (MPa): 193 x 103 in tension
• Melting Range: 2550-2650°F (1399-1454°C)

Fe, <0.03% C, 16-18.5% Cr, 10-14% Ni, 2-3% Mo, <2% Mn, <1% Si, <0.045% P, <0.03% S Background Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. Grade 316L, the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures. Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures. Key Properties These properties are specified for flat rolled product (plate, sheet and coil) in ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as pipe and bar in their respective specifications.

The list is intended as a comparison of functionally similar materials not as a schedule of contractual equivalents. If exact equivalents are needed original specifications must be consulted. Possible Alternative Grades Table 5. Possible alternative grades to 316 stainless steel. Grade Why it might be chosen instead of 316? 317L Higher resistance to chlorides than 316L, but with similar resistance to stress corrosion cracking. Corrosion Resistance Excellent in a range of atmospheric environments and many corrosive media - generally more resistant than 304. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 60°C. Considered resistant to potable water with up to about 1000mg/L chlorides at ambient temperatures, reducing to about 500mg/L at 60°C. 316 is usually regarded as the standard “marine grade stainless steel”, but it is not resistant to warm sea water. In many marine environments 316 does exhibit surface corrosion, usually visible as brown staining. This is particularly associated with crevices and rough surface finish. Heat Resistance Good oxidation resistance in intermittent service to 870°C and in continuous service to 925°C. Continuous use of 316 in the 425-860°C range is not recommended if subsequent aqueous corrosion resistance is important. Grade 316L is more resistant to carbide precipitation and can be used in the above temperature range. Grade 316H has higher strength at elevated temperatures and is sometimes used for structural and pressure-containing applications at temperatures above about 500°C. Heat Treatment Solution Treatment (Annealing) - Heat to 1010-1120°C and cool rapidly. These grades cannot be hardened by thermal treatment. Welding Excellent weldability by all standard fusion and resistance methods, both with and without filler metals. Heavy welded sections in Grade 316 require post-weld annealing for maximum corrosion resistance. This is not required for 316L. 316L stainless steel is not generally weldable using oxyacetylene welding methods. Machining 316L stainless steel tends to work harden if machined too quickly. For this reason low speeds and constant feed rates are recommended. 316L stainless steel is also easier to machine compared to 316 stainless steel due its lower carbon content. Hot and Cold Working 316L stainless steel can be hot worked using most common hot working techniques. Optimal hot working temperatures should be in the range 1150-1260°C, and certainly should not be less than 930°C. Post work annealing should be carried out to induce maximum corrosion resistance. Most common cold working operations such as shearing, drawing and stamping can be performed on 316L stainless steel. Post work annealing should be carried out to remove internal stresses. Hardening and Work Hardening 316L stainless steel does not harden in response to heat treatments. It can be hardened by cold working, which can also result in increased strength. Applications Typical applications include: •         Food preparation equipment particularly in chloride environments. •         Pharmaceuticals •         Marine applications •         Architectural applications •         Medical implants, including pins, screws and orthopaedic implants like total hip and knee replacements •         Fasteners
