ASTM Grade HD Steel vs. EN 1.4837 Stainless Steel

Both ASTM grade HD steel and EN 1.4837 stainless 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. 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 ASTM grade HD steel and the bottom bar is EN 1.4837 stainless steel.
