304 stainless steel is a versatile stainless steel material, corrosion performance than the 200 series stainless steel stronger. Also relatively good high temperature, can be high to the 1000-1200 degrees. 304 stainless steel with excellent corrosion resistance and good resistance to intergranular corrosion. On the oxidizing acid, obtained in the experiment: the concentration of <= 65% of the boiling temperature, the nitric acid, 304 stainless steel with strong corrosion resistance. Most of the alkali solution and organic acids and inorganic acids also has good resistance to corrosion.
