The corrosion resistance of stainless steel high-pressure valve is better than that of carbon steel high-pressure valve. It has good corrosion resistance in pulp and paper production process. And 316 stainless steel high-pressure valve are also resistant to the marine environment, some of the valve body material requirements are relatively high, generally 301.304.316 and other material selection is widely used in chemical industry, shipping, medicine, food machinery and other industries.
