ASTM A182 Grade F3VCb vs. AISI 309Cb Stainless Steel

Both ASTM A182 grade F3VCb and AISI 309Cb stainless steel are iron alloys. Both are furnished in the annealed condition. They have 65% of their average alloy composition in common. There are 33 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is ASTM A182 grade F3VCb and the bottom bar is AISI 309Cb stainless steel.
