Product details
Gnee Steel Group is one of the recognized suppliers and exporters in the 321 Stainless Steel Tubes and Tubes market, where 18% of the minimum chromium content in it provides corrosion and oxidation resistance and must also contain at least 10.5 percent chromium. Depending on the grade, it may contain much higher chromium levels and additional alloy ingredients such as molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorus and selenium. 321H alloy is a general purpose austenitic stainless steel with a cubic structure of centered faces. It is essentially non-magnetic in annealed state and can only harden cold. Its low carbon content compared to alloy 302 provides better corrosion resistance in welded structures.
Alloy 321 (UNS S32100) is an austenitic stainless steel that carries molybdenum with much greater resistance to chemical attacks compared to conventional nickel-chromium austenitic stainless steels such as Alloy 304. In addition, the 321H Alloy offers greater resistance to lateral elongation, breakage stress, and stress at high temperatures than conventional stainless steels. It is a low carbon steel or "L" grade that provides resistance to sensitization during welding and other thermal processes. This combination of properties is the reason for the widespread use of these alloys that account for nearly half of total U.S. stainless steel production.
