ASTM A572 Grade 65 vs. EN 1.4855 Stainless Steel
Both ASTM A572 grade 65 and EN 1.4855 stainless steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 49% of their average alloy composition in common. There are 28 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.
For each property being compared, the top bar is ASTM A572 grade 65 and the bottom bar is EN 1.4855 stainless steel.
