Product description

304 stainless steel is widely used as a kind of chromium - nickel stainless steel. As a widely used steel,its characteristic is corrosion resistance, good heat resistance, high strength in low temperature, easy to process on punching, bending and other thermal processing, non hardening heat treatment (when temperature is -196℃ to 800℃), Corrosion resistant in the atmosphere,if it is in the industrial atmosphere or heavy pollution areas, you need to clean in time to avoid corrosion.
