  • Steel Article Having Improved Contact Fatigue Resistance
    Publication number: 20180355464
    Abstract: A steel article with resistance to contact fatigue having a martensitic stainless steel body with a hardened surface layer and a core. The hardened surface layer is tempered martensite and M7C3 carbides, has at least 1.6 wt. % carbon, and has a depth equal to or greater than the depth where the steel article experiences the maximum shear stress when placed in service.
    Type: Application

  • Steel article having improved contact fatigue resistance and a method of making
    Patent number: 10087512
    Abstract: A steel article with resistance to contact fatigue having a martensitic stainless steel body with a hardened surface layer and a core. The hardened surface layer is tempered martensite and M7C3 carbides, has at least 1.6 wt. % carbon, and has a depth equal to or greater than the depth where the steel article experiences the maximum shear stress when placed in service. Also, a method of manufacturing such as a steel article having resistance to contact fatigue comprising: providing a martensitic stainless steel article having a prior austenite grain size of ASTM #6 or smaller; carburizing the surface of the steel article; solution treating the steel article; tempering the steel article for a first time; hardening the steel article; cooling the steel article at a temperature below 0° F.; and tempering the steel article for a second time.
