321 stainless steel can effectively control the formation of chromium carbide by adding stabilized element titanium, and has better intergranular corrosion resistance and high temperature strength. 321 stainless steel has good abrasion resistance in organic acid and inorganic acid of different concentration and temperature, especially in oxidizing medium. It can be used to manufacture abrasion-resistant acid containers, linings of abrasion-resistant equipment and transportation pipelines.

321 stainless steel bars include:
321 Stainless steel bright bar
321 Stainless steel grinding rod
321 Stainless steel hexagonal rod
321 stainless steel angle bar
321 Stainless steel square bar
321 Stainless steel flat bar
321 Stainless steel angle bar
321 Stainless steel channel bar
