EN 1.4848 Stainless Steel vs. ASTM Grade HT Steel

Both EN 1.4848 stainless steel and ASTM grade HT steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 85% 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 HT steel.
