EN 1.4020 Stainless Steel vs. ASTM B685 Alloy

EN 1.4020 stainless steel belongs to the iron alloys classification, while ASTM B685 alloy belongs to the otherwise unclassified metals. There are 15 material properties with values for both materials. Properties with values for just one material (16, in this case) are not shown.

For each property being compared, the top bar is EN 1.4020 stainless steel and the bottom bar is ASTM B685 alloy.
