EN 1.4806 Stainless Steel vs. ASTM Grade HD Steel

Both EN 1.4806 stainless steel and ASTM grade HD steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 69% 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 EN 1.4806 stainless steel and the bottom bar is ASTM grade HD steel.
