US20090202382A1 HIGH MANGANESE STEEL STRIPS WITH EXCELLENT COATABILITY AND SUPERIOR SURFACE PROPERTY, COATED STEEL STRIPS USING STEEL STRIPS AND METHOD FOR MANUFACTURING THE STEEL STRIPS 有权
具有优异的可承受性和超级表面性能的高锰钢条，使用钢带的涂层钢条和制造钢带的方法

HIGH MANGANESE STEEL STRIPS WITH EXCELLENT COATABILITY AND SUPERIOR SURFACE PROPERTY, COATED STEEL STRIPS USING STEEL STRIPS AND METHOD FOR MANUFACTURING THE STEEL STRIPS
Abstract:
A high-ductility, high-strength and high Mn steel strip used for steel strips of automobiles requiring superior formability and high strength, a plated steel strip produced by using the same, and a manufacturing method thereof are disclosed. The high Mn steel strip comprises, by weight %, 0.2˜1.5% of C, 10˜25% of Mn, 0.01˜3.0% of Al, 0.005˜2.0% of Si, 0.03% or less of P, 0.03% or less of S, 0.040% or less of N, and the balance of Fe and other unavoidable impurities. The high-ductility, high-strength and high Mn steel strip, and the plated steel strip produced by using the same have superior surface properties and plating characteristics.
