254 SMO (UNS S31254)

Features Thanks to its low carbon content 254SMO alloy minimizes the danger of carbide precipitation This alloy can pass the STRAUSS TEST even after undergoing 1 hour of sensitization within a temperature range of 600℃-1000℃. It avoids intergranular corrosion during welding processes. 254SMO demonstrates strong corrosion resistance in pure sulfuric acid Under slightly higher temperatures 254SMO can maintain high crevice corrosion resistance properties Mechanical strength higher than other austenitic stainless steels Chemical Analysis
