Cold Worked R05400 Tantalum vs. Ductile Hardened ASTM B540
Both cold worked R05400 tantalum and ductile hardened ASTM B540 are otherwise unclassified metals. Both are furnished in the cold worked (strain hardened) condition. There are 18 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.
For each property being compared, the top bar is cold worked R05400 tantalum and the bottom bar is ductile hardened ASTM B540.
