Description

304 stainless steel is a kind of universal stainless steel material, rust resistance than 200 series of stainless steel material is stronger. High temperature resistance is also better, can be as high as 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance. For oxidizing acids, it is concluded in the experiment that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration of less than or equal to 65% of the boiling temperature. It also has good corrosion resistance to alkali solution and most organic and inorganic acids.
