410. Three general classifications are used to identify stainless steel. Our stainless steel is very popular for use on boat and marine rub rail projects. Remarks: 1) Ferritic SUS447J1 and SUSXM27 may contain at most 0.60% Ni. 304 is non-magnetic What distinguishes Type 316 from Type 304 is the addition of molybdenum up to a maximum of 3%. 522 0 obj <>stream It has excellent forming and welding characteristics. Alloy 310 (UNS S31000) is an austenitic stainless steel developed for use in high temperature corrosion resistant applications. Cart. out our complete section of type 316 stainless steel tables. Type 316 is also austenitic, non-magnetic, and thermally non-hardenable stainless steel like Type 304. %PDF-1.5 %���� (2) May have at most 0.6% Mo added. It is the most readily available in a variety of product forms. Stainless steel, a rust-resistant variation of ordinary steel, comes in many standard types, each identified by a number. 316 Stainless Steel Iron deposits interrupt the passivation layer on stainless steel, so steel wool or steel-bristled brushes should never be used on or near it. Stainless Steel Grading . When molybdenum is added to the stainless steel the pitting corrosion resistance improves. Insta-Blak SS-370 is a liquid concentrate solution used for swab-on or immersion blackening of stainless steel surfaces. � bi �l ��$Xk@�΂! endstream endobj startxref Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. Pressing / Drawing Typical applications include: Automotive trim, kitchen utensils, sinks, washing machine parts and industrial pipe and tube. As the steel does not contain nickel or molybdenum, it is less expensive than any of the 300 series. 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. The concentration of the various components that make up SS 304 must be kept at a certain and precise level. The crevice needs to be large enough for the corrosive solution to penetrate and small enough where the solution remains stagnant. Our stainless steel is very popular for use on boat and marine rub rail projects. The carbon content is held to 0.08% maximum, while the nickel content is increased slightly. In sharp corners or overlapping surfaces the passive film on stainless steel can break down. No products in the cart. Search for: 0. Fabricating stainless steel 304 requires care and precision. Choose the correct grade of stainless steel to meet the environment and application. Free-machining bar grade. Being a ferritic material, 430 is liable to brittle fracture at sub-zero temperatures, and cannot be used in cryogenic applications. When Stainless Steel is chosen for its resistance to corrosion it is important to use the correct type or grade. As the chromium is dissolved chlorides bore into the stainless creating a smooth wall pit. 0 303 Stainless Steel. Because of its high chromium and moderate nickel content, Alloy 310 is resistant to sulfidation and can also be used in moderately carburizing atmospheres. It is immune to sterilizing solutions, most of the organic chemicals and a wide variety of inorganic chemicals. Standard martensitic grade for low-duty hardened applications . There is also “Pitting Corrosion” which is usually caused by acid chloride. 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. Type 316 is also used extensively for surgical implants. 420. Call us at (800) 888-2044 today! The balanced austenitic structure of Alasannya, karena bentuk dan hasil akhir dalam pengerjaan stainless steel 304 terkesan jauh lebih baik dan rapih dibanding stainless lainnya. Fabricating SS 304/AISI 304. Learn about EPi's trial kit. Numerous types of stainless steel serve a variety of purposes and many overlap. Stainless steel equipment can be made out of all three types of stainless steel: 316, 304 or 430. &�A� a �tPL()���6��0a��b�p�:;&��&�$�d/@��ΡhE0)�H@R�b�jE�P0�;�R+�hk� ����u�C#��F �l0�B���B3'u6�I�X���NR. 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. 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. However, the stainless steel has good corrosion resistance in mildly corrosive environments and good resistance to oxidation at elevated temperatures. Two, known as 430 and 304, have different properties that come from mixtures of iron and other metals in slightly different amounts. A Chromium (17-20%), Nickel (9-13%), Iron Alloy modified with the addition of titanium to prevent carbide precipitation and resulting intergranular corrosion that can take place in certain mediums when operating in the 800-1200°F (427-649°C) temperature range. Stainless steel is famous for its corrosion resistance, fire and heat resistance, hygiene, and high strength-to-weight properties. Where cost is a larger factor than life span, 430 may be more suitable. A lot can be done to maintain stainless steel of either grade. Molybdenum is one of the single most useful alloying additives in the fight against corrosion.
