HIGH DUCTILITY STEEL HAVING EXCELLENT CORROSION AND WEAR RESISTANCE

摘要

PURPOSE: High-ductility steel is provided to obtain excellent corrosion resistance and wear resistance by employing Cu and properly controlling the contents of C and Mn. CONSTITUTION: High-ductility steel with excellent corrosion resistance and wear resistance comprises Mn of 8-15wt.%, Cu of 3wt.% or less(0 is exclusive), Cr of 8wt.% or less(0 is exclusive), and Fe and inevitable impurities of the remaining amount, where the content of C satisfies the following equations, 33.5C+Mn>=25 and 33.5C-MnΔ23.
