Abstract

This invention relates to an impact-resistant super-low manganese group steel consists of following elements: carbon, silicon, manganese, chromium, nickel, molybdenum, and iron, wherein the manganese contained is not over 1.5% (w/w), preferably not over 0.15% (w/w). After proper heating processing, the hardness of the present steel may be over HRc50, and impact value over 50 J/cm<2> by testing under room temperature.
