EN 1.4865 Stainless Steel vs. Chromium 33
Both EN 1.4865 stainless steel and chromium 33 are metals with high concentrations of iron and nickel. This makes them relatively similar, despite formally belonging to different alloy families. They have 84% of their average alloy composition in common. There are 21 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 EN 1.4865 stainless steel and the bottom bar is chromium 33.
