EN 1.4848 Stainless Steel vs. ASTM Grade HI Steel

Both EN 1.4848 stainless steel and ASTM grade HI steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 95% of their average alloy composition in common.

For each property being compared, the top bar is EN 1.4848 stainless steel and the bottom bar is ASTM grade HI steel.
