The metalworking powers-that-be developed these classes to consolidate chemical and mechanical properties into categories based on the needs of customers’ uses. Resists dry atmospheres, freshwater, mild alkalis and acids, steam, and hot gases. attached to some of the grades. 317L is a variation of 317 suitable for heavy-gauge welding. High strength and hardness. Older grades often feature a three-digit identifier established by the Society of Automotive Engineers (SAE). (Actually, there are a few hundred.). Combination of strength and ductility to withstand severe forming methods. Corrosion resistance comparable to 302. Its popularity also means there are seemingly a million different types of stainless steel grades. Heat treating won’t harden them, and they are always magnetic. Grades of Stainless Steel Stainless Steel Grades and Mechanical Properties. AISI 316: Well known stainless steel as well, with very high corrosion resistance, it is usually reserved to very aggressive chloride environment such as swimming pools or seawater applications. Properties of Grade 310/310S Stainless Steel. The Group combines cost-efficient production with a global sales and distribution network and offers customers one of the broadest product ranges on the market. %PDF-1.4 Marine, chemical, and petrochemical industries, Excellent weldability, toughness, and fabricating characteristics, Tubing for bus frames, hopper cars, chutes, storage tanks, shipping containers. Deciding between the two most popular stainless tubing grades, 304 and 316? Duplex stainless steel grades are covered by major standards, such as EN, ISO, ASTM for a number of products and/or applications (see Appendix 1). 5 S9 ATLAS STEELS – SPECIALTY STEELS PRODUCT REFERENCE MANUAL SECTION 9: APPENDICES Printed November 2000 Note 1: Single values are maxima unless otherwise stated. Addition of sulfur or selenium gives it best machinability of all austenitic grades, but reduces corrosion resistance compared to 304. Check out our guide to their key differences. . Its popularity also means there are seemingly a million different types of stainless steel grades. Ferritic stainless is, These steels, also of the 400 series, usually contain 11.5%-18% chromium and have higher levels of carbon than their ferritic counterparts. ‘Super austenitic’ grade with very high corrosion resistance, especially to strong acids and chlorides. “L” denotes low carbon content, which equals increased corrosion resistance. Heat treating won’t harden them, and they are always magnetic. . << /Length 3 0 R Need more clarification on what separates 316 and 316L? Grade 310S is a lower carbon version, less prone to embrittlement and sensitisation in service. (Actually, there are a few hundred.) Must harden for best heat and corrosion resistance. Knives, ball bearings, gauge blocks, dies. The high chromium and medium nickel content make these steels capable for applications in reducing sulphur atmospheres containing H2S. Heat treatment of these steels can result in a, Deciding between the two most popular stainless tubing grades, 304 and 316? Excellent toughness. High tensile, torque strength. Auto exhaust systems, heat exchangers, furnace liners. [1] Stainless steel does not stain, corrode, or rust as easily as ordinary steel (it stains less, but it is not stain-proof). Note 3: 3CR12 generally conforms with both ASTM A240 grade … The next most widely used grades are the ferritic steels Comments Off; Stainless steel is a material with tons to offer. Stainless steel grades listed in the international standard ISO 15510:2010 Comparative designations of grades with similar composition from other important standards. The most common type of stainless steel in use is grade 304. grade with exceptional resistance to hot chlorides and sulfides. Grade UNS No. Need more clarification on what separates 316 and 316L? stream Check out our. Its popularity also means there are seemingly a million different types of, Combination of strength and ductility to withstand severe forming methods. Click on the links in the table below to access concise datasheets covering all the common stainless steels. You can see that different stainless steel grades are born to play different roles in steel tube forming. Readily welded and formed. This grade has an 18-20% chromium content and a 8-10.5% nickel content by mass, although 304L exists as a low-carbon alternative to 304, and 304Cu and 304N versions, enriched in copper and nitrogen respectively, also exist. Within families, you’ll find various grades that help to describe specific properties of the alloy such as toughness, magnetism, corrosion resistance and alloy composition. Nickel also enhances the corrosion resistance of stainless steel. Improved corrosion resistance over 316. Stainless Steel Grades. ‘Super duplex’ grade with exceptional resistance to hot chlorides and sulfides. Virtually non-magnetic. Corrosion resistance, Food and drink, sanitary, cryogenic and pressure. Common Name; S 201-2; S 30100; S 30100; S 30100; S 30100; S 30100; S 30200; S 30300; S 30400 2 0 obj Good combination of corrosion resistance, formability, mechanical properties. High-carbon, moderate corrosion resistance, superior strength and hardness. Steel Grades, Properties and Global Standards - 1 Outokumpu Outokumpu is the world’s leading stainless steel producer. Pitting corrosion resistance. Excellent corrosion resistance. Pulp and paper machinery, ink and dying processes, acetic acid distillation, Aircraft, heat exchangers (up to intermediate temperatures), Corrosion resistance comparable to 409, better surface finish, Caskets, applications requiring better finish than 409. -- the main ones being austenitic, ferritic, and martensitic. Is slightly weaker than 304. These steels, also of the 400 series, usually contain 11.5%-18% chromium and have higher levels of carbon than their ferritic counterparts. Stainless Steel Grades Chart PDF -- Types of Stainless Steel. AISI 304: Well known stainless steel grade, very close to the 201 grade but with lower mechanical properties. Type 304—the most common grade; the classic 18/8 stainless steel. Austenitic steels mainly reside in the 200 and 300 series. In general Grade 304 stainless steel is practically immune to sigma phase formation, but not so those grades with higher chromium contents (Grade 310) with molybdenum (Grades 316 and 317) or with higher silicon contents (Grade 314).
