Deep Drawing Steel (DDS)
Definition - What does Deep Drawing Steel (DDS) mean?
Deep drawing steel is a widely used process for forming steel metal sheet into box- or cup-like structures. This process is used to manufacture small to mid-sized metal equipment. Pots and pans for cooking, containers, sinks and automobile parts such as panels and gas tanks are among a few of the items manufactured by the steel sheet deep drawing process.
Corrosionpedia explains Deep Drawing Steel (DDS)
Rigid tools consisting of punches and various dies and binders are used to perform the drawing process on steel sheet metal. The punch (a mechanical hydraulic press) produces a desired shape to the base of the part once drawn. The die cavity matches the punch and has a little wider clearance to allow for its passage. The sheet on which the drawing process needs to be applied is placed in the plate holder, tightly clamped between the die and the binder. The punch hits the sheet to form it into the required shape of the die. Because of this force the metal sheet folds inside the die and assumes the necessary required shape.
The steel equipment made from the deep drawing process exhibits high corrosion resistance for a large number of applications. This process also imparts good resistance to stress corrosion cracking.
