More Information
Summary:Provided is an austenite steel having excellent ductility including 8 wt% to 15 wt% of manganese (Mn), 3 wt% or less (excluding 0 wt%) of copper (Cu), a content of carbon (C) satisfying relationships of 33.5C + Mn ‰¥ 25 and 33.5C - Mn ‰¤ 23, and iron (Fe) as well as unavoidable impurities as a remainder. According to an aspect of the present invention, austenite is stabilized and generation of carbides in a network form at austenite grain boundaries is inhibited by adding copper (Cu) favorable to inhibition of carbide formation with respect to manganese and appropriately controlling contents of carbon and manganese, and thus, high economic efficiency may also be achieved while ductility and wear resistance are improved.
