Super Austenitic stainless steel combines with 904L, 254SMO, AL-6XN, Alloy 20, etc.
Alloy 20 is stainless steel with extremely
high corrosion resistance to sulfuric acid.
It can be used in a wide range of sulfuric acid environments,
including high concentration, high-temperature environments.
It possesses excellent intergranular corrosion resistance and stress corrosion cracking resistance.
254SMO (UNS S31254) is a high corrosion resistant austenitic stainless steel with high nickel, high chromium, high molybdenum alloy design, and provides excellent corrosion resistance in severe corrosion environments such as high-temperature seawater.
Weidouli's 904L plug valves have been put into Plumbum and Zinc Metallurgy use all the way, especially applied to oxygen pressure acid leaching technology. In our domestic market, our valves are designated used by SHENZHEN ZHONGJIN LINGNAN NONFEMET CO., LTD, WESTERN MINING, whose projects are architected by Changsha Engineering & Research Institute Ltd (Of Nonferrous Metallurgy.) Their oxygen pressure acid leaching technology adoption is based on SherrittGordon in Canada.
