Cold Finished AISI 304L vs. Cold Finished SAE-AISI 51B60

Both cold finished AISI 304L and cold finished SAE-AISI 51B60 are iron alloys. Both are furnished in the cold worked (strain hardened) condition. They have 71% of their average alloy composition in common. There are 31 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is cold finished AISI 304L and the bottom bar is cold finished SAE-AISI 51B60.
