AUSTENITIC STEEL WITH EXCELLENT RESISTANCE FOR ADIABATIC SHEAR BAND FORMABILITY AND METHOD FOR MANUFACTURING THEREOF

摘要

The present invention relates to an austenitic steel and, more specifically, relates to an austenitic steel with excellent resistance for adiabatic shear band formability; and a method to manufacture the same. According to the present invention, the austenitic steel comprises: 0.4-1.5 wt% of carbon (C); 14-21 wt% of manganese (Mn); 5.0 wt% or less of cobalt (Co) (excluding 0 wt%); and the remainder consisting of Fe and inevitable impurities.
