EN 1.4852 Stainless Steel vs. SAE-AISI 94B17 Steel

Both EN 1.4852 stainless steel and SAE-AISI 94B17 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 30 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is EN 1.4852 stainless steel and the bottom bar is SAE-AISI 94B17 steel.
