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. Our 5160 generally measures 32-35 Rockwell delivered. (Compared to 1080 measuring in the mid 20's).
Typical chemistry:C .63, Mn .86, Si .23,CR .83
