CR-MN STEEL WHICH IS AUSTENITIC AT ROOM TEMPERATURE, BUT TRANSFORMS TO MARTENSITE UPON DEFORMATION (C+N)0.35()

摘要

A steel comprising selected amounts of chromium, manganese and nitrogen and/or carbon, the amounts of chromium, manganese, and nitrogen and/or carbon being selected such that the resultant steel is austenitic at room temperature but transforms significantly to martensite steel upon deformation.
