It has good corrosion resistance to reducing salts and various inorganic acids and organic acids, alkali and salts

Have good corrosion resistance, heat resistance, low temperature strength and mechanical properties, stamping and bending and other good thermal processing, no heat treatment hardening phenomenon, no magnetism.

As a general corrosion-resistant steel, heat-resistant steel, the most versatile.

Used for drinking water, drinking water, cold water, hot water, gas, medical gas, household goods, cabinets, indoor pipelines, water heater, boiler, bathtub, auto parts, medical equipment, building materials, chemistry, food industry, agriculture, ship parts.

S31608
