1.4541 ASTM S32100 321 Stainless Steel
This grade is a titanium stabilised austenitic stainless steel. The addition of titanium to 321 stainless Steel helps improve its welding properties and the elevated temperature properties of the steel. This stainless steel offers excellent oxidation resistance and corrosion resistance. It offers higher creep and stress rupture properties that 304 austenitic stainless steel grade. 321 stainless steel possesses excellent resistance to intergranular corrosion when worked or welded in temperatures with the carbide precipitation range of 427-818°C.
We welcome export enquiries for stainless steel. Contact our sales office and consult our shipping policy for further details.

| Analysis |
|
| Form of Supply | Yaang Stainless Steel is a supplier and manufacturer of Stainless Steel Flanges, Stainless Steel Pipe Fittings, Stainless Steel Pipes, and Stainless Steel bars. We can guillotine cut pieces to your required sizes. 321 stainless steel round bar is available and diameters can be cut to your requirements. Precision ground Stainless Steel bars can be supplied, providing high quality stainless Steel bars to close tolerances. |
| Applications | 321 stainless steel is used widely in industries such as automotive, chemical, construction and aerospace. Typical applications are exhaust systems and manifolds, heat exchangers, bellows, oil refinery equipment, furnace parts and firewalls. |
| Corrosion Resistance | Stainless steel 321 grade has similar corrosion resistance to that of 304 austenitic grade. However it is better suited for applications where an unstabilised chromium nickel steel, such as 304, would be susceptible to intergranular corrosion. It offers excellent corrosion resistance in most natural waters (rural and industrial), provided the chloride, salt and concentrations of hydrochloric and organic acids are low. |
| Welding | Stainless steel 321 is readily weldable with most welding procedures. Oxyacetylene welding is not recommended due to possible carbon pick up in the weld area. Due to intergranular carbide precipitation 321 can be welded without loss of corrosion resistance and post weld annealing is not normally required, except for service in more extreme conditions. We recommend you contact your welding consumables supplier who should be able to provide you full assistance and information on welding stainless steel. |
| Forging | Heat the 321 stainless steel slowly and uniformly throughout the section to 1150-1250°C. Re heat as necessary and avoid working below 900°C. Cool in air. |
| Scaling Temperature | The oxidation resistance of a stainless steel is traditionally termed as the scaling temperature. This is the temperature at which the oxidation rate of a stainless steel becomes unacceptably high. The safe scaling temperature for continuous service of 321 is 875°C. In an oxidising and reducing sulphurous atmosphere the scaling temperature of 321 stainless steel is lowered. |
