System Description: 304 stainless steel is the most widely used chromium-nickel stainless steel [1], as a widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; stamping, bending and other heat Good processing, no heat treatment hardening (use temperature -196 °C ~ 800 °C). Corrosion resistance in the atmosphere, if industrial atmosphere or heavily polluted areas, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. With good processing properties and weldability. Plate heat exchangers, bellows, housewares (1, 2 tableware, cabinets, indoor pipes, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical appliances, building materials, chemicals, food industry , agriculture, ship parts and so on. 304 stainless steel is a nationally recognized food grade stainless steel.
