304 stainless steel is a universal stainless steel material with stronger rust resistance than 200 series stainless steel materials. It also has good high temperature resistance, reaching up to 1000-1200 degrees Celsius. 304 stainless steel has excellent stainless steel corrosion resistance and good resistance to intergranular corrosion. In the experiment, it was found that 304 stainless steel has strong corrosion resistance in nitric acid below boiling temperature with a concentration of \u2264 65%. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.
