EN 1.4874 Stainless Steel vs. Grade TDCrV Steel

Both EN 1.4874 stainless steel and grade TDCrV steel are iron alloys. They have a modest 33% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is EN 1.4874 stainless steel and the bottom bar is grade TDCrV steel.
