SA312/312M TP310/310S Stainless Steel Pipes and Tubes
Type 310 is the grade of stainless steel containing the highest chromium-nickel content of all grades - 25% chromium, 20% nickel, It is chiefly known for its superior scaling and corrosion resistance and it excels all other grades in its high temperature physical properties. At extremely high temperatures, its creep strength and resistance to brittling far surpasses all other austenitic grades. In the annealed state it is non-magnetic. Type 310 is a non-heat treatable alloy produced by the electric-furnace process, which concurs with the exacting standards of the aircraft industry. Type 310S is a low carbon austenitic stainless steel. Known for its ability to withstand high temperature applications, Type 310S, which is a lower carbon version of Type 310.
