321 Stainless steel 

Austenitic stainless steel is equivalent to domestic 0Cr18Ni10Ti
US brands are: 321, S32100, TP321
Among the 321 stainless steels, Ti exists as a stabilizing element, but it is also a heat-strength steel, which is much better than 316L in high temperature. 321 stainless steel is used in organic acids and inorganic acids of different concentrations and temperatures, especially in oxidation. It has good abrasion resistance in the medium and is used to manufacture the lining and conveying pipeline of wear-resistant acid container and wear-resistant equipment.
321 stainless steel is Ni-Cr-Ti austenitic stainless steel, its performance is very similar to 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.
321 stainless steel has excellent high temperature stress breaking (Stress Rupture) performance and high temperature creep resistance (Creep Resistance) stress mechanical properties are better than 304 stainless steel. Suitable for welding components used at high temperatures.

It is used in field open-air machines for chemical, coal, and petroleum industries with high resistance to intergranular corrosion, heat-resistant parts for building materials, and parts with difficult heat treatment, such as:
1. Petroleum waste gas combustion pipeline
2. Engine exhaust pipe
3. Boiler casing, heat exchanger, furnace components
4. Dust-proof parts for diesel engines
5. Boiler pressure vessel
6. Chemical transport vehicles
7. Expansion joint
8. Spiral welded pipe for furnace pipe and dryer
9. Aircraft
