HIGH-MANGANESE STEEL WITH SUPERIOR WELDABILITY AND METHOD FOR MANUFACTURING HOT-DIPPED GALVANIZED STEEL SHEET FROM SAME |
| 摘要 |
The present invention relates to high-manganese steel with superior weldability and to a method for manufacturing hot-dipped galvanized steel sheets from same. The high-manganese steel according to one aspect of the present invention is characterized by comprising, 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%; and B: 0.0005-0.01%, with the remainder being Fe and unavoidable impurities. The present invention may provide high-manganese hot-dipped galvanized steel sheets, having high strength and processability and superior surface quality, which can prevent plating failures caused by manganese. |
