What is it?
Drawing Steel (sometimes noted as DS or DQ) specifies the quality of a specific steel product. This type of steel is more ductile than commercial because of higher standards in the making of the steel. As such, it performs better during the manufacturing process. The steel’s low carbon level allows it to be used in welding, yet its relatively low yield (compared to other steels) make it susceptible to fatigue and denting. This grade if often used in automotive stamping, particularly body sides, roofs, floor pans, doors and hoods.
Today, DS Type B is used to describe DK or DQSK designated steel. Traditionally, Drawing Steel falls within these parameters: C – 0.02/0.08; Mn – 0.50 max.; P – 0.020 max.; S – 0.030 max.
