Drawing Steel (DS) Type B

DS Type B Replaces Drawing Quality (DQ) and Drawing Quality Special Killed Steels (DQSK)

Drawing Steel (DS) Type B has a greater degree of ductility and is more consistent in performance than Commercial Steel Type B because of higher standards in production, selection and melting of steel. The improved ductility and uniformity of properties of Drawing Steel compared to Commercial Steel sheet means that it provides improved performance during manufacturing. If drawing depth is more severe, please refer to Deep-Drawing Steels or Extra Deep-Drawing Steels.

DS Type B must be ordered within the following compositional limits:
C - 0.02/0.08, Mn - 0.50 max., P - 0.020 max., and S - 0.030 max.

• Weldability – Low carbon level makes this a good welding candidate.

• Fatigue Performance – Relatively low yield, compared to other steels, makes this grade more susceptible to fatigue than higher strength steels.

• Denting – Relatively low yield strength, compared to other steels, may make DS Type B more susceptible to denting.  For additional capabilities, please check our dent-resistant steels.

• Applications - DS Type B is the most common material found in automotive stampings today.  This material offers the formability that is required to produce parts with some depth of draw.  Typical applications would include body sides, roofs, floor pans, reinforcements, doors, deck lids and hoods.
