Work Hardened ASTM B522 Class I vs. Work Hardened ASTM B685 Alloy
Both work hardened ASTM B522 class I and work hardened ASTM B685 alloy are otherwise unclassified metals. Both are furnished in the cold worked (strain hardened) condition. There are 17 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.
For each property being compared, the top bar is work hardened ASTM B522 class I and the bottom bar is work hardened ASTM B685 alloy.
