Abstract:
Steel alloys having high yield and ultimate tensile strengths in combination with high toughness based on medium carbon secondary hardening steel compositions having low cobalt content. Nickel is added to the medium carbon secondary hardening steel compositions to increase the yield and tensile strengths and fracture toughness. Applications of a steel alloy of the present disclosure include structural applications requiring high strength and high fracture toughness, such as aircraft landing gear.
