Deep Drawing Stainless Steel Sheet

This is achieved by redrawing the part through a series of dies.

Deep drawing stainless steel sheet.

Stainless steel and not rust free as often indicated is one of the hardest materials for deep drawing. Frequently a 100 percent increase compared to plain carbon steel of the same thickness is required. The process is considered deep drawing when the depth of the drawn part exceeds its diameter. As a result of the tension generated in the material during the deep drawing annealing is often required.

Tooling material must be of sufficient hardness with a highly polished surface finish. Pots and pans for cooking containers sinks automobile parts such as panels and gas tanks are among a few of the items manufactured by sheet metal deep drawing. Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. This process is sometimes called drawing and is not to be confused with the bulk deformation process of drawing discussed earlier.

They are very formable and the austenitic grades have substantially higher ductility than carbon steels. While ferritic grades are less formable they still have outstanding ductility and can be deep drawn easily. Rather uniform material thickness can be achieved in stainless steel shapes. Lower cycle times per piece than metal spinning and welding operations.

It is thus a shape transformation process with material retention. Monolithic parts can be formed from a single piece of sheet or plate material. Deep drawing stainless steel due to the rapid workhardening rates of stainless steels more press power and press energy is required. Can create deep parts while avoiding welds.

The flange region experiences a radial drawing stress and a tangential compressive stress due to the material retention pro. Deep drawing is a manufacturing process that is used extensively in the forming of sheet metal into cup or box like structures.
