Advantage of 304 :


304 stainless steel is one of the most widely used chromium - nickel stainless steel, as a widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Stamping, bending and other thermal processing, no heat treatment hardening phenomenon (use temperature -196℃~800℃). Corrosion resistance in the atmosphere, if it is an industrial atmosphere or heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. It has good machinability and weldability. Plate heat exchanger, corrugated pipe, household articles (1, 2 class tableware, cabinet, indoor pipeline, water heater, boiler, bathtub), auto parts (windshield wipers, mufflers, mold products), medical appliances, building materials, chemistry, food industry, agriculture, ship parts, etc. 304 stainless steel for the national approval of food grade stainless steel.
