EN 1.4865 Stainless Steel vs. ASTM Grade HH Steel

Both EN 1.4865 stainless steel and ASTM grade HH steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 74% of their average alloy composition in common.

For each property being compared, the top bar is EN 1.4865 stainless steel and the bottom bar is ASTM grade HH steel.
