PURPOSE: A cold-rolled steel sheet with high plating property and high workability and a method for producing the same are provided improve workability and plating property by lowering the content of the carbon which degrades the workability. CONSTITUTION: A cold-rolled steel sheet with high plating property and high workability comprise alloy composition. The alloy composition comprises carbon(C) 0.004~0.02 weight%, manganese(Mn) 1.0~2.5 weight%, sulfur(S) 0.005~0.01 weight%, aluminum(Al) 0.01~0.1 weight%, nitrogen(N) 0.004~0.01 weight%, phosphorus(P) 0.05~0.1 weight%, boron(B) 0.0005~0.002 weight%, and niobium(Nb) 0.06~0.15%. The alloy composition comprises rest iron(Fe) and inevitable impurities. |
