Stainless Steel Alloy 20

Stock Sizes: Custom sizes available upon request

Alloy 20 exhibits exceptional corrosion resistance and outstanding mechanical properties as well as relatively straightforward fabrication. Alloy 20 is corrosion resistant to hot sulfuric acids when compared to austenitic stainless steels such as 316 or 317.

Most welding methods can be used to weld Alloy 20, except for oxyacetylene welding. Alloy 20 can also be hot formed using the same forces required to hot work austenitic stainless steels. In terms of machinability, outstanding finishes are possible using the same set-up and process speeds used for austenitic stainless steels, such as 316 or 317.
