About 310S Austenitic Stainless Steel
What is 310S Austenitic Stainless Steel?
Grade 310S stainless steel is an austenitic chrome-nickel stainless steel, which features good oxidation resistance, corrosion resistance and acid and alkali resistance.
Grade 310S stainless steel also referred to as the UNS S31008/W.Nr. 1.4845 stainless steel.
Besides, it embodies excellent high temperature resistance. With high content of chromium and nickel elements, i.e., 25Cr-20Ni, 310S embodies much better creep strength which allows it to work continuously at high temperature (1150 °C). The high temperature resistant steel tube is specially used for manufacturing electric heating tubes and the like.
The more severely carburizing atmospheres of industrial heat treating furnaces require alloy 330. Grade 310S is not suggested for the severe thermal shock of repeated liquid quenching.
Alloys 310S is available in all standard mill forms including pipe, rod, bar, plate, sheet, strip and foil products.
