Introduction of 304 stainless steel:
304 stainless steel is one kind of universal stainless steel, anti rust performance than the 200 series stainless steel material is better. High-temperature is better, the general use of less than 650 DEG C temperature limit. 304 stainless steel with excellent stainless corrosion resistance corrosion resistance and good resistance to intergranular. The oxidizing acid, obtained in the experiment: the concentration of less than 65% of the boiling temperature below the nitric acid, the corrosion resistance of 304 stainless steel has a very strong. Also has good corrosion resistance ability of the alkali solution and most organic and inorganic acid.

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.
