Age Hardened ASTM B540 vs. Aged 250 Maraging Steel
Age hardened ASTM B540 belongs to the otherwise unclassified metals classification, while aged 250 maraging steel belongs to the iron alloys. There are 20 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 age hardened ASTM B540 and the bottom bar is aged 250 maraging steel.
