Grade 360 Molybdenum vs. SAE-AISI O1 Steel

Grade 360 molybdenum belongs to the otherwise unclassified metals classification, while SAE-AISI O1 steel belongs to the iron alloys. There are 16 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 grade 360 molybdenum and the bottom bar is SAE-AISI O1 steel.
