EN 1.4832 Stainless Steel vs. ASTM Grade HE Steel

Both EN 1.4832 stainless steel and ASTM grade HE steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 92% of their average alloy composition in common.

For each property being compared, the top bar is EN 1.4832 stainless steel and the bottom bar is ASTM grade HE steel.
