ABSTRACT:
As for high strength stainless steels and method for manufacturing the high strength stainless steels, the strength of the stainless steels are enhanced by adding an appropriate amount of both nitrogen and niobium to austenitic stainless steels, inhibiting boron, an impure element, and decreasing the carbon content. The strength of the stainless steels are further enhanced by such heat treatment as control rolling and low temperature solution heat treatment applied to the stainless steels after the control rolling.
