Stainless Steel 321 is a stabilized austenitic stainless steel. It is stabilized for weldments subject to sever corrosive conditions and service from 800 to 1600 F. It is similar to stainless steel grade 304 but with a titanium amount of at least five times the level of carbon. This also helps advance the mechanical properties of the steel at higher temperatures.
Applications:
- Airplane exhaust manifolds
- Boiler shells
- Process equipment
- Expansion joints
- Cabin heaters
- Fire walls
- Flexible couplings
- Pressure vessels
