Cold Drawn SAE-AISI 1137 vs. Strain Hardened S20910 Stainless Steel
Both cold drawn SAE-AISI 1137 and strain hardened S20910 stainless steel are iron alloys. Both are furnished in the cold worked (strain hardened) condition. They have 59% of their average alloy composition in common. There are 29 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.
For each property being compared, the top bar is cold drawn SAE-AISI 1137 and the bottom bar is strain hardened S20910 stainless steel.
