EN 1.4865 Stainless Steel vs. ASTM Grade HL Steel

Both EN 1.4865 stainless steel and ASTM grade HL steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 82% of their average alloy composition in common. There are 28 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

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