Applications. The most common austenitic stainless steel and most common of all stainless steel is Type SS 304, also known as 18/8 or A2. 6% Molybdenum stainless steel alloy can usually be found in the forms of seamless and welded tube, specialty forgings, plate/sheet or round bar. Avesta® 254 SMO. From the naked eye, it can be extremely difficult to tell the difference between grades of stainless steel. ASTM B649 904L Stainless Steel Round Bars. Its high molybdenum content combined with elements such as nickel and copper gives UNS S31254 excellent resistance to pitting and crevice corrosion. EN 1.4547 ASTM type - ASTM UNS S31254 Microstructure Austenitic Typical applications . Acceptable seawater-corrosion. 254 SMO, UNS S31254, WNR 1.4547, 6Mo, 6 Molybdenum, 254 SMO Stainless Steel , SMO 254. 316/316L stainless steel has excellent corrosion resistance at normal temperatures in ordinary atmospheric conditions withstanding some natural acids, chlorine and chloride. Typical Analysis . Super Duplex Stainless Steel – UNS S32750 / UNS S32760. They have 83% of their average alloy composition in common. This product was developed especially for oil and gas offshore platforms and the pulp and paper industry. Ultra 254 SMO A 6% molybdenum and nitrogen-alloyed austenitic stainless steel with extremely high resistance to both uniform and localized corrosion. 316 stainless steel has more carbon in it than 316L. Alloy 254, which is also found under the brand name Sandvik 254 SMO and UNS S31254, is a super austenitic stainless steel that is well known for its outstanding resistance to pitting, crevice corrosion, stress cracking, and fatigue corrosion. Print / Download PDF. One reason for these unique properties is Alloy 254’s specific chemical make-up that includes: Fe (remainder) […] 316 and 316L stainless steel alloys are both marine-grade steels, but they do possess some key differences. Stainless steel grade 254 SMO™, UNS S31254, 1.4547, 6MO, F44 Stainless steel 254SMO ( UNS S31254 ) is a very high end austenitic stainless steel.It is designed with a combination of impact toughness resistance to chloride stress corrosion cracking, and pitting and crevice corrosion with strength that is twice that of the stainless steel 300 series. Brand name. But even though it has less carbon, 316L is very similar to 316 in almost every way. Rostfrit stål Acero Inoxidable ... 1.4547 is a high-alloy austenitic stainless steel developed for use in seawater and other aggressive chloride-bearing media. Rustfrit stål Acciai Inossidabli . It is relatively easy to fabricate and weld. Hence, specialized tools must be used to machine these alloys. 254 SMO: The Leanest* 6Mo Stainless on the Market The 6Mo stainless steels, whether 254 SMO (S31254), AL-6XN (N08367), or 1925 hMo and 25-6Mo (both covered by N08926), are substantially similar with respect to significant performance characteristics.3 The chemical composition of the 254 SMO stainless steel typically has a slightly higher copper content than the AL-6XN alloy (Table 1). This alloy has a high nickel content and about 6 percent molybdenum, together with copper and nitrogen additions. Posted by Arthur Harris & filed under Company News. ASTM A276 347 Stainless Steel Round Bars. Tube and tube compression fittings manufactured from 6 Mo stainless are available in our Duoloc and Ringlok as part of our Special Metals range. Stainless Steel 304/304L, 316/316L, 317L, 321, 321H, 347, 347H, 904L, 254SMO Nipples, USD 2.6 - 8,000/Piece, Stainless Steel, Forged, Nipple. | Outstanding resistance to localized corrosion such as pitting and crevice corrosion, as well as to stress-corrosion. 316L has a lower proportion of carbon in its composition. Technical personnel, supported by the research laboratory of Outokumpu, can draw on years of field experience with Type 316/316L to help you make the technically and economically correct materials decision. 254 SMO Round Bars. Super Duplex Steel also is known as SAF 2507 or Super Duplex 2507 with UNS S32750 and UNS S32760 (1.4410 / 1.4501 / F53 / F55 / 2507) is a high alloy duplex stainless steel with a PRE value of min.40*. We’re talking parts damage and replacement, repair costs including labor and downtime. Les aciers inoxydables, grâce à leur composition chimique, sont des alliages métalliques pour leur nature résistantes à la corrosion.. L’acier inox AISI 316L, appelé "1.4404" aussi, est diffèrent de l’acier inox AISI 316 (1.4401) pour la mineur quantité de carbone présente.La « L » signifie, en effet, « low carbon » (faible teneur en carbone). The main difference between 304 vs 316 stainless steel is the composition and corrosion resistance, SS304 doesn’t contain molybdenum while SS316 contains 2-3% molybdenum. UNS S15500 15-5 Ph Bars. 254SMO is an austenitic stainless steel designed for maximum resistance to pitting and crevice corrosion. The high performance austenitic stainless steels such as 254 SMO® have a fully austenitic microstructure in the quench annealed condition. In more corrosive environments a Duplex grade may be a more suitable option for extra protection against pitting and crevice corrosion. To qualify as 316L stainless steel, the amount of carbon cannot exceed 0.03%. ASTM A276 316Ti Stainless Steel Round Bars. If desired we machine finished parts according to customer drawings. Standards. Type SS 304 is extensively used in such items as, cookware, cutlery, and kitchen equipment. SMO 254 is austenitic stainless steel product that is designed for the maximum resistant to crevice corrosion and pitting. Qualities of 316 vs. 316L Stainless Steel. Super Duplex S32750 and Super Duplex S32760 has 25% chromium (25Cr Duplex), 4% molybdenum, and 7% nickel also known as … UNS … We are the best UNS S31254 Tubes manufacturer and supplier offering UNS S31254 Seamless Tubes, UNS S31254 Welded Tubes, UNS S31254 ERW / EFW Tubes, Stainless Steel UNS S31254 Round Tubes. UNS S17400 17-4 Ph Bars. Outokumpu is prepared to discuss individual applications and to provide data and experience as a basis for selection and application of Type 316/316L. In addition, AISI 304 has a 18% Cr and 8% Ni and therefore known as 18-8 stainless steel, while AISI 316 has a 16% Chromium and 10% Nickel. METALCOR offers a wide range of STAINLESS STEEL products. The variation with time of the open circuit potential of high molybdenum containing stainless steel (Type 254 SMO) was measured in 4% sodium chloride solution in the temperatures range 30–100°C. Type SS 316 is the next most common austenitic stainless steel. The last thing you need is your outdoor electrical enclosure rusting out on you.
