Cold Finished AISI 310 vs. Cold Finished AISI 317

Both cold finished AISI 310 and cold finished AISI 317 are iron alloys. Both are furnished in the cold worked (strain hardened) condition. They have 86% of their average alloy composition in common. There are 33 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is cold finished AISI 310 and the bottom bar is cold finished AISI 317.
