AISI 321H Stainless Steel vs. Nickel 600
AISI 321H stainless steel belongs to the iron alloys classification, while nickel 600 belongs to the nickel alloys. They have a modest 35% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.
For each property being compared, the top bar is AISI 321H stainless steel and the bottom bar is nickel 600.
