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; good hot workability such as stamping and bending, 

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.

304 stainless steel is suitable for food processing, storage and transportation. Has good processability and weldability. Plate heat exchangers,

 bellows, household products (Class 1 and 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, 

mufflers, molded products), medical appliances, building materials, chemicals, food industry , agriculture, ship parts, etc.
