HIGH MANGANESE STEEL STRIPS WITH EXCELLENT COATABILITY AND SUPERIOR SURFACE PROPERTY, COATED STEEL STRIPS USING STEEL STRIPS AND METHOD FOR MANUFACTURING THE STEEL STRIPS |
摘要 |
<p>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.</p> |
