EN 1.3551 Steel vs. Chromium 33

EN 1.3551 steel belongs to the iron alloys classification, while chromium 33 belongs to the otherwise unclassified metals. They have a modest 38% of their average alloy composition in common, which, by itself, doesn't mean much. There are 17 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.

For each property being compared, the top bar is EN 1.3551 steel and the bottom bar is chromium 33.
