High Carbon alloy spring steel with chromium added for hardenability.
5160 has good wear resistance and is known for outstanding toughness.
Hardening capability of 57-58 HRC.
As a spring steel, 5160 will typically come harder than your standard
carbon steels. This material is hardened to spring hardness and measures 32-35 Rockwell C.
Typical chemistry:C .63, Mn .86, Si .23,CR .8
