ASTM Grade HE Steel vs. EN 1.4823 Stainless Steel

Both ASTM grade HE steel and EN 1.4823 stainless steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 93% of their average alloy composition in common. There are 31 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 ASTM grade HE steel and the bottom bar is EN 1.4823 stainless steel.
