SAE-AISI H13 Steel vs. EN 1.4971 Stainless Steel

Both SAE-AISI H13 steel and EN 1.4971 stainless steel are iron alloys. They have a modest 38% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI H13 steel and the bottom bar is EN 1.4971 stainless steel.
