EN 2.4889 Nickel vs. Grade TDSiCr Steel

EN 2.4889 nickel belongs to the nickel alloys classification, while grade TDSiCr steel belongs to the iron alloys. They have a modest 26% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is EN 2.4889 nickel and the bottom bar is grade TDSiCr steel.
