摘要
Provided is a steel having excellent weldability and impact toughness in a welding zone comprising: by weight (wt.) %, carbon (C): 0.1% to 0.3%, manganese (Mn): 11% to 13%, iron (Fe) as a residual component thereof, and other inevitable impurities, and positive and negative segregation zones in a layered form. The positive segregation zone comprises austenite and epsilon martensite, and the negative segregation zone comprises, by area fraction, epsilon martensite of less than 5% and alpha martensite.
