Product Details

310S is austenitic cr-ni stainless steel with good oxidation resistance and corrosion resistance, because of the higher percentage of chromium and nickel, 310S has much better creep strength, can continue to work at high temperature, has good high temperature resistance.

310S stainless steel is austenitic cr-ni stainless steel, with good oxidation resistance, corrosion resistance, high temperature resistance, because of a higher percentage of chromium and nickel, has much better creep strength, can continue to work at high temperature, with good high temperature resistance.


Nickel (Ni), chromium (Cr) content is high, has good resistance to oxidation and corrosion resistance, acid and alkali resistance, high temperature performance. High temperature resistant steel pipe is dedicated to manufacturing occasions such as the electric heating furnace tubes. Austenite stainless steel after the increase of carbon content, due to its solid solution strengthening effect, the strength was improved, the chemical composition of austenite stainless steel features based on chromium, nickel, add, tungsten molybdenum, niobium and titanium elements, due to its organization is face-centered cubic structure, thus has high strength and creep at high temperature strength. Melting point 1470℃, 800℃ began to soften, the allowable stress continued to reduce.
