UNS S31254. 254 SMO ® stainless steel bar, also known as UNS S31254, was originally developed for use in seawater and other aggressive chloride-bearing environments. This grade is considered a very high end austenitic stainless steel; mainly comprised of between 19.5% and 20.5% chromium, 17.5% to 18.5% nickel, 6% to 6.5% molybdenum and .18% to .22% nitrogen. 6 Moly Grades - Penn Stainless6 Moly Grades are well suited for applications related to chemical processing, heat exchangers, desalinization and more. The most common 6 Moly grades for piping products are 254SMO (UNS S31254) and AL6XN (UNS NO8367). Plate materials are generally available in both grades from stock, enabling reduced manufacturing times.

Oct 25, 2018 · General Properties. Alloy 254 SMO is a very high end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content. It demonstrates outstanding resistance to pitting, crevice corrosion stress cracking, and corrosion fatigue uniform corrosion. Alloy 254 SMO is substantially stronger than the common austenitic grades, with strength nearly twice that of 300 series stainless steel.

Sep 11, 2011 · We offered a 5 year warranty on products made of 254 SMO or AL6XN or one other similar alloy. We did not offer a longer warranty on anything. You are asking a lot. Anything with much iron in it is probably not going to work for you. Nickel alloys might offer some hope, but they get very expensive very quickly and can be difficult to fabricate. Electropolishing & Deburring Service for Exotic & Other Electropolishing Services for Unusual Stainless Steel. To enhance your parts made from unusual stainless steels, submit them for Able Electropolishings signature treatment. Parts that undergo our electropolishing process are free of surface imperfections that could compromise cycle-life performance. Electropolishing also provides stainless Hydrochloric acid Sandvik Materials TechnologyHydrochloric acid. These corrosion data are mainly based on results of general corrosion laboratory tests, carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen). All concentrations are given in weight-% and the solvent is water if nothing
Oct 07, 2015 · Comparing Superaustenitic Stainless Steel Alloys. stainless steel, AL-6XN, 254 SMO, 904L, Hastelloy C-22. Many industries are already using higher corrosion-resistant alloys beyond traditional stainless steel. In the high-purity and sanitary industries, products such as shampoos, conditioners, deodorants, sports drinks, ketchup, salsa, and al6xn vs 254 smo - Casting-china AL-6XN possesses approximately 5-10% greater strength than 254 SMO and is also ASME approved up to 800°F, whereas 254 SMO is approved up to 700°F. AL-6XN has been assigned to P Number 45 in Section IX of the ASME Boiler & Pressure Vessel code, Group 4 and uses 625 weld filler as well.
