Cold Rolled EN 1.4477 vs. Ductile Hardened ASTM B540

Cold rolled EN 1.4477 belongs to the iron alloys classification, while ductile hardened ASTM B540 belongs to the otherwise unclassified metals. There are 23 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is cold rolled EN 1.4477 and the bottom bar is ductile hardened ASTM B540.
