310S (old grade 0Cr25Ni20/ new grade 06Cr25Ni20) is an austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance, due to the higher percentage of chromium and nickel, 310S has much better creep strength, can continue to work at high temperatures, has good high temperature resistance.
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.
This is the most cost effective grade of steel. So the 310S Stainless Steel wire Price is lower compared to other grades of stainless steels and all metallic products in general. There are different versions of the material with low carbon and high carbon content. The low carbon version, 310S wires are very good for welding applications as they have less carbide precipitation and less localized corrosion.
