Abstract:
A secondary hardening steel alloy substantially lacking Cobalt is disclosed. In spite of the substantial lack of Cobalt, a steel alloy of the present disclosure has a low Stage II crack growth, and a high fracture toughness. Applications of a steel alloy of the present disclosure include structural applications, including aircraft landing gear.
