310S Stainless steel

310S is an austenitic chromium-nickel stainless steel. We called A240 310S in ASTM standard, SUS310S in JISG4303 standard, 1.4845(X8CrNi25-21) in Europe standard, AS 310S in Australia standard, SA240/SA240M 310 in ASME standard. They are equivlence material. 310S has good oxidation resistance, corrosion resistance, due to high percentage of chromium and nickel, 310s has much better creep strength, can continue to work at high temperatures, has good resistance to high temperature.

310S Stainless steel Machinability

Grade 310S stainless steel can be machined similar to that of grade 304 stainless steel.

310S Stainless steel Welding

Grade 310S stainless steel can be welded using fusion or resistance welding techniques. Oxyacetylene welding method is not preferred for welding this alloy.

310S Stainless steel Hot Working

Grade 310S stainless steel can be hot worked after heating at 1177°C (2150°F). It should not be forged below 982°C (1800°F). It is rapidly cooled to increase the corrosion resistance.

310S Stainless steel Cold Working

Grade 310S stainless steel can be headed, upset, drawn, and stamped even though it has high work hardening rate. Annealing is performed after cold working in order to reduce internal stress.
