The carbon content is held to 0.08% maximum, while the nickel content is increased slightly. Fabricating stainless steel 304 requires care and precision. Differences between Type 304 and Type 316: What distinguishes Type 316 from Type 304 is the addition of molybdenum up to a maximum of 3%. endstream endobj startxref Our stainless steel is very popular for use on boat and marine rub rail projects. As the steel does not contain nickel or molybdenum, it is less expensive than any of the 300 series. Numerous types of stainless steel serve a variety of purposes and many overlap. Stainless steel, a rust-resistant variation of ordinary steel, comes in many standard types, each identified by a number. The balanced austenitic structure of 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. When molybdenum is added to the stainless steel the pitting corrosion resistance improves. 416. 304 contains no trace of molybdenum, 316 contains 2.1% molybdenum 430 is somewhat difficult to form, 304 is easier to form and weld � bi �l ��$Xk@�! Differences between Type 430 and Type 304:430 grade stainless steel is magnetic, However, the stainless steel has good corrosion resistance in mildly corrosive environments and good resistance to oxidation at elevated temperatures. Pressing / Drawing Note: (1) May contain at most 0.6% Ni. SUS447J1 and SUSXM27 may contain at most 0.50% Ni, 0.20% Cu, and 0.50% Ni + Cu; and any alloy element other than listed can be added if required. 420. This grade is easy to form and fabricate with excellent resistance to corrosion. The introduction to nickel in 304 makes it a much more corrosion resistant grade than 430 however, it does make it more expensive. Two, known as 430 and 304, have different properties that come from mixtures of iron and other metals in slightly different amounts. Under the right condition of the three stated factors, Type 304 stainless steel bucket could pit through in less than 8 hours. Both types 304 and 316 are easily welded and formed Type 316 is also austenitic, non-magnetic, and thermally non-hardenable stainless steel like Type 304. 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. Samples available to purchase - CALL #262-786-9330. It is a nonmagnetic steel. Maintaining your stainless steel. out our complete section of type 316 stainless steel tables. Cart. 304 is non-magnetic This alloy, therefore, is specified for equipment in the medical industry, pharmaceutical manufacturing, and sterile area. Martensitic Stainless Steels.

Standard duplex stainless steel - high resistance to pitting and stress corrosion. Because of its high chromium and moderate nickel content, Alloy 310 is resistant to sulfidation and can also be used in moderately carburizing atmospheres. 6950 South Tucson WayUnit FCentennial, CO, 80112, T: 303-752-0076F: 303-752-0288info@cleanroomworld.com, © 2020 Cleanroom World All rights reserved, TYPES OF STAINLESS STEEL – 304, 316 and 430. A badly treated 304 will not look better than a well-treated 430. Alloy 310 (UNS S31000) is an austenitic stainless steel developed for use in high temperature corrosion resistant applications. Stainless Steel Grading . Stainless steel equipment can be made out of all three types of stainless steel: 316, 304 or 430. 303 is a non-magnetic austenitic stainless steel that contains 18% chromium and 8% nickel. 482 0 obj <>/Filter/FlateDecode/ID[<75EF15E4B581094AAEF38A9B4D3CEF2C><6F380646A8845B4391A39C915FA06F5B>]/Index[466 57]/Info 465 0 R/Length 84/Prev 63161/Root 467 0 R/Size 523/Type/XRef/W[1 2 1]>>stream Three general classifications are used to identify stainless steel. It has excellent forming and welding characteristics. %%EOF 2507Cu. "\@J�A�����/ ѧ���Ș2��q���n � There is also “Pitting Corrosion” which is usually caused by acid chloride. Being a ferritic material, 430 is liable to brittle fracture at sub-zero temperatures, and cannot be used in cryogenic applications. The concentration of the various components that make up SS 304 must be kept at a certain and precise level. Standard martensitic grade for low-duty hardened applications . Heat resisting applications up to 759oC. As the chromium is dissolved chlorides bore into the stainless creating a smooth wall pit. Both types are non magnetic Hal ini disebabkam karena stainless steel 304 memiliki karakteristik bentuk yang mudah saat dilas. 0 Call us at (800) 888-2044 today! The biggest difference between the grades is molybdenum is added to Type 316 to increase corrosion and pitting resistance. 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. h�b```�-,�s����(���q��֣K&}@A���:2 b@���p�H���� �G����>Gm�M,}�D*X-R����s10��Ҍ@���N� iV�C`qF�R!�/��� c�9 430 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. 522 0 obj <>stream
