Process Features
With hydrochloric acid and iron oxide on hot rolled steel sheet after clearing get a nice, smooth surface. After formation, the surface of the steel sheet tends to be more cold-rolled plate surface.
By pickling the steel sheet surface oxide scale, so that the steel sheet surface defects easily exposed, so the main problem is to ensure a high quality surface production process control should be considered.

EN10111 DD11 steel plate/sheet is stamping and cold forming steels,it is suitable for non-structural press work and forming.It's tensile strength is around 440 MPa (there is different min strength point at the different thickness.) DD11 yield strength is from 170MPa to 340 MPa. (different min strength point at the different thickness.)
