Grade 705C Zirconium vs. SAE-AISI H13 Steel

Grade 705C zirconium belongs to the otherwise unclassified metals classification, while SAE-AISI H13 steel belongs to the iron alloys. There are 16 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.

For each property being compared, the top bar is grade 705C zirconium and the bottom bar is SAE-AISI H13 steel.
