Abstract
There is provided a high-manganese steel with superior coating adhesion and a method of producing a hot-dip galvanized steel sheet from same. According to an aspect of the present disclosure, a high-manganese steel is characterized by including, by weight, C: 0.3-1%, Mn: 8-25%, Al: 1-8%, Si: 0.1-3.0%, Ti: 0.01-0.2%, Sn: 0.06-0.2%, B: 0.0005-0.01%, with the remainder being Fe and inevitable impurities. The present disclosure can provide a high-manganese and hot-dip galvanized steel sheet with superior surface quality as well as with high strength and workability by preventing coating failures that may be caused by manganese.
