What is the difference between 310 stainless steel, 310S stainless steel and 304 stainless steel?

310 stainless steel is austenitic chromium-nickel stainless steel with good oxidation resistance, corrosion resistance and high temperature resistance. It is often used in light industry, heavy industry, daily necessities and decoration industries. Among them, the more representative 310 stainless steel plate is often used in escalators, elevators, doors, machinery and packaging, transportation systems, home furnishing, freezers, auto parts, kitchen appliances, etc., with a wide range of applications.

When it comes to 310 stainless steel, the most notable feature is undoubtedly high temperature resistance.

When it comes to 310 stainless steel, we have to mention 310S stainless steel. What material is 310S stainless steel?

The comprehensive performance of 310S stainless steel is better than that of 310. Because of the high content of nickel and chromium, it has excellent oxidation resistance, corrosion resistance, acid and alkali resistance, and high temperature resistance. 310S stainless steel has good resistance to intergranular corrosion and excellent resistance to chloride stress corrosion.

310S stainless steel is mainly used in petroleum, electronics, chemical, pharmaceutical, machinery, military, aerospace, light textile and other industries, and is often used in the manufacture of furnace tubes, boiler superheaters, and heat exchanger fittings.

What is the difference between 310S stainless steel and 304 stainless steel?

1. Chemical composition: The carbon content, nickel content, silicon content and chromium content of 304 stainless steel are lower than those of 310S stainless steel.

2. Performance: 310S stainless steel has excellent corrosion resistance, oxidation resistance and high temperature resistance, and 304 stainless steel has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. In terms of high temperature resistance, 310S stainless steel is better than 304. The high temperature resistance of 310S is about 1000 °C, and the high temperature resistance of 304 is about 800 °C.

3. 304 stainless steel is often used in the food and medical industry, industry and furniture industry, and 310S stainless steel is used in petroleum, electronics, chemical industry, furnace tubes, boiler superheaters, heat exchange pipe fittings and other fields.
