  • Copper Containing Rail Steel
    Publication number: 20170349986
    Abstract: Steel railroad rails including carbon, manganese, silicon and greater than 0.45 wt % to 1 wt % copper are provided having greater hardness and yield strength than standard steel rails containing less than 0.45 wt % copper. As an example, the ultimate tensile strength of the steel rails is from 1170 MPa to 1725 MPa. As an additional example, the hardness of the steel rails measured 2 mm from the running surface of the rail is from 35 to 50 on the Rockwell C scale.

  • Method for producing steel with retained austenite
    Publication number: 20060011274
    Abstract: The present invention relates to a process for producing steel with retained austenite. In one embodiment, the process comprises the steps of heating a steel alloy to produce austenite, quenching the steel to produce martensite, and carbon partitioning to transfer carbon from the martensite to the austenite.
