Chromium 33 vs. SAE-AISI M36 Steel

Chromium 33 belongs to the otherwise unclassified metals classification, while SAE-AISI M36 steel belongs to the iron alloys. 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 (9, in this case) are not shown.

For each property being compared, the top bar is chromium 33 and the bottom bar is SAE-AISI M36 steel.
