  • Method for pressurized water quenching of rolled steel products
    Patent number: 4592788
    Abstract: A method for pressurized water quenching of rolled steel products wherein the product is cooled so abruptly on its surface, at a quenching from a final rolling temperature of approximately 1000.degree. C. to an equilibrium temperature of above 500.degree. C., the temperature of the core immediately after the completion of the quenching is no more than only 30.degree. C. below the original final rolling temperature. The shorter cooling periods lead to a thinner martensitic layer, and a greater portion of the ferritic-perlitic core mass resulting in an increase in ductility with little change in strength.
