ASTM A182 Grade FR vs. AISI 303Se Stainless Steel

Both ASTM A182 grade FR and AISI 303Se stainless steel are iron alloys. Both are furnished in the annealed condition. They have 74% of their average alloy composition in common. There are 32 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 FR and the bottom bar is AISI 303Se stainless steel.
