304 stainless steel is the most widely used chromium nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Stamping, bending and other hot workability are good, without heat treatment hardening (use temperature – 196 ℃~800 ℃). It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. It has good processability and weldability.
