SS321 bar has good abrasion resistance in organic acids and inorganic acids of different concentrations and temperatures, especially in oxidizing media, and is used to make wear-resistant acid containers.and linings of wear-resistant equipment and transmission pipelines.

321 stainless steel bar is Ni-Cr-Ti type austenitic stainless steel, its performance is very similar to 304, but due to the addition of metallic titanium, it has better grain boundary corrosion resistance and high temperature strength. The addition of metallic titanium effectively controls the formation of chromium carbide.

4. Its excellent high-temperature stress rupture performance (Stress Rupture) and high-temperature creep resistance (Creep Resistance) stress mechanical properties are better than those of 304 stainless steel

321 stainless steel round rod application range and application areas:

It is used in outdoor open-air machines in the chemical, coal, and petroleum industries that require high resistance to grain boundary corrosion, heat-resistant building material parts, and parts that are difficult to heat treat, such as:

1. Oil waste gas combustion pipeline
2. Engine exhaust pipe
3. Boiler shell, heat exchanger, heating furnace components
4. Silencer parts for diesel engines
5. Boiler pressure vessel

6.Chemical transport truck

7.Expansion joint

8. Spiral welded pipes for furnace pipes and dryers
