304 stainless steel plate is one kind of universal of stainless steel materials, anti-rust properties than 200 series stainless steel materials. High temperature resistant aspects are relatively good, high to 1000-120 degrees. 304 stainless steel has good corrosion resistance and corrosion resistance between good corrosion wafer. To oxidizing acids, in the experiment, the concentration of the temperature than 65% of nitric acid in boiling
