EN 1.4849 Stainless Steel vs. AISI W2 Steel
Both EN 1.4849 stainless steel and AISI W2 steel are iron alloys. They have a modest 39% of their average alloy composition in common, which, by itself, doesn't mean much. There are 21 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 EN 1.4849 stainless steel and the bottom bar is AISI W2 steel.
