EN 1.4854 Stainless Steel vs. SAE-AISI 1039 Steel
Both EN 1.4854 stainless steel and SAE-AISI 1039 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 31 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 1.4854 stainless steel and the bottom bar is SAE-AISI 1039 steel.
