The chemical composition of 304 stainless steel:

The characteristics of 304 stainless steel
304 stainless steel is one of the most extensive application of chromium - nickel stainless steel, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties. Corrosion in the atmosphere, if is industrial atmosphere or heavy pollution area, the need to clean to avoid corrosion. Suitable for processing, storage and transportation of food. Has good processing properties and weldability. Plate heat exchanger, corrugated pipe, household goods, building materials, chemical, food industry etc.. 304 stainless steel for the country approved food grade stainless steel.
