304 stainless steel is a nationally recognized food grade stainless steel. 1. Stainless steel is classified according to thickness: (1) thin plate (0.2mm-4mm) (2) medium plate (4mm-20mm) (3) thick plate (20mm-60mm) (4) extra thick plate (60-115mm) 2. Stainless steel is classified according to production method: (1) hot rolled steel plate (2) cold rolled steel plate

304 stainless steel is a widely used chromium nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Good hot workability such as stamping and bending, no heat treatment hardening phenomenon (service temperature - 196 ℃ ~ 800 ℃). It is resistant to corrosion 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, bellows, household products (Class 1 and 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, silencers, molded products), medical appliances, building materials, chemistry, food industry, agriculture, ship parts, etc.
