Pickled DD11(StW22) steel is mainly used as stamping and cold forming steels.

Pickled DD11(StW22) size range:
tensile strength σ b≤700MPa
Yield Strength δ s≤600MPa
Thickness : 1.0~6.0mm
Width : 700~1650mm
Weight : ≤38.64 T
ID : 610mm,760mm

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.

Pickled 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.
