654SMO UNS S31254 pipe stainless

654SMo (S32654, 1.4652) super austenitic stainless steel is a super austenitic stainless steel containing 23% nickel, 25% chromium and 7% molybdenum. Its anti-corrosion ability is much better than ordinary austenitic steel. The smelting method of 654SMO super austenitic stainless steel: the currently popular argon-oxygen decarburization refining method abroad (VOD or AOD), and the continuous casting method of stainless steel can also be used. However, because the amount of 654SMO steel is much smaller than that of ordinary austenitic stainless steel, and it is smelted in an AOD or VOD refining furnace (usually more than 20T per furnace), the supplier does not want to overload the inventory, so our company's Wuhu Special Alloy uses vacuum Steel is made in an induction refining furnace, coupled with electroslag remelting and refining, and then forged into blanks to process round steel, forgings, flanges, etc.
254SMO (UNS N31254) is often referred to as the "6% Moly" grade due to its molybdenum content. 254SMO is an austenitic stainless steel with high content of chromium, molybdenum and nitrogen, which has good resistance to pitting and crevice corrosion, especially in environments containing halide ions, such as chloride, bromide and fluoride solutions . Compared with Alloy 904L, Alloy 20, Alloy 825, 254SMO has excellent chlorination resistance and is particularly suitable for brackish water environments, such as brackish water or seawater.
