EN 1.1133 Steel vs. Chromium 33
EN 1.1133 steel belongs to the iron alloys classification, while chromium 33 belongs to the otherwise unclassified metals. They have a modest 33% 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 1.1133 steel and the bottom bar is chromium 33.
