Chromium 33 vs. S35315 Stainless Steel

Both chromium 33 and S35315 stainless steel are metals with high concentrations of iron and nickel. This makes them relatively similar, despite formally belonging to different alloy families. They have 90% of their average alloy composition in common. There are 21 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.

For each property being compared, the top bar is chromium 33 and the bottom bar is S35315 stainless steel.
