Aged 250 Maraging Steel vs. Precipitation Hardened S66286 Stainless Steel
Both aged 250 maraging steel and precipitation hardened S66286 stainless steel are iron alloys. Both are furnished in the aged (precipitation hardened) condition. They have 74% of their average alloy composition in common. There are 25 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 aged 250 maraging steel and the bottom bar is precipitation hardened S66286 stainless steel.
