Product introduction
304 stainless steel is a normal stainless steel material, its rust-proof performance is better than 200 series stainless steel material, high temperature resistance is also good, can be up to 1000 - 1200 degrees. 304 stainless steel has excellent corrosion resistance and intergranular corrosion resistance. For oxidizing acid, it is found that 304 stainless steel has strong corrosion resistance in nitric acid with concentration less than 65% below boiling temperature. It also has good corrosion resistance to alkali solution and most organic and inorganic acids.
