The HC260LA cold rolled micro alloyed steel coil combines a guaranteed 260 MPa yield strength with the deep drawing behavior that automotive stamping lines depend on. Zhengde produces the grade through continuous pickling, cold tandem rolling, full continuous annealing and a final skin pass, with niobium and titanium additions that refine the grain and deliver stable mechanical properties from coil start to finish. The bright skin-passed surface carries a controlled roughness
