310S Stainless Steel Coil

310S Stainless steel coil Price in China ,Manufacturer of 310S Stainless Steel coil

310S stainless steel is austenitic chromium-nickel stainless steel, has good oxidation resistance, corrosion resistance, high temperature resistance, because of the higher percentage of chromium and nickel, making it has much better creep strength, can continue to work at high temperature, has good high temperature resistance.
Because of the high content of nickel (Ni), chromium (Cr), has good oxidation resistance, corrosion resistance, acid and alkali resistance, high temperature resistance, high temperature resistant steel pipe is dedicated to the manufacture of electric furnace tube and other occasions, austenitic stainless steel increases the content of carbon, due to its solid solution strengthening effect so that the strength is improved,
The austenitic stainless steel has high strength and creep strength at high temperature due to its face-centered cubic structure, which is based on chromium and nickel.
Melting point 1470℃, 800℃ began to soften, allowable stress continued to reduce.

Improve the common carbon tool steels brittle nature, and to extend the life of tools.
Vacuum degassing refining steel, stable quality.
Good hardenability, oil cold hardening (quenching and deformation less) good toughness and wear resistance, durable tools.
