Made of heat-strength steel, 321 stainless steel, this kind of seamless stainless steel tubes is much better than 316L in the respect of high temperature. Its performance is very similar to that of 304, but due to the addition of titanium metal, it has better resistance to intergranular corrosion and high temperature strength. Due to the addition of titanium metal, it effectively controls the formation of chromium carbide. It has good abrasion resistance in organic acids and inorganic acids with different concentrations and different temperatures, especially in oxidizing media.
