Cold Drawn AISI 303 vs. Cold Finished AISI 317

Both cold drawn AISI 303 and cold finished AISI 317 are iron alloys. Both are furnished in the cold worked (strain hardened) condition. They have a moderately high 91% 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 drawn AISI 303 and the bottom bar is cold finished AISI 317.
