Forming Stainless Steel Sheet

The punch press is basically open type single moving mechanical or hydraulic transmission with a long and narrow table.

Forming stainless steel sheet.

An example drawing note might read material. These alloys also tend to respond well to cold forming. The rollers used to finish the sheet emboss the surface finish onto the sheet. We can accommodate a stainless steel blank up to 32 inches in diameter.

Some of them are carbon steel stainless steel copper and aluminium. Typically the rollers are precision ground with a smooth finish. As the punch rises. Another good alternative is duplex stainless steel which combines the properties of austenitic and ferritic stainless steels.

As you bend a stainless steel sheet the bend area cold hardens increasing the amount of pressure required to finish the bend. Previous studies by shinagawa and takuda indicate that warm forming of stainless steel sheet reduces martensite formation when forming at elevated temperatures. It should also be noted that austenitic stainless steels can t be heat treated meaning that cold forming may be your only option. The resulting mill rolled finish in the sheet stock is termed 2b as a finish designation for stainless.

Stainless steel sheet 16 gauge 304 2b. Austenitic stainless steel can be used to produce deep drawn components that require very high elongations and thus stainless steel is widely specified for the production of hollowware. Stainless steel sheets are cut into blanks then placed in the hydroforming press one at a time over a punch. Hydroforming stainless steel is a cost effective process that results in a higher quality product than die stamping methods can produce.

Bright annealed 2r stainless steel sheet without any additional polishing. 3 this publication is intended to indicate selected processes that make optimum use of stainless steel s forming potential. At the end of the article we will be discussing different forming methods used with sheet metal. In addition elon has specified 3mm thick stainless steel which greatly increases forming tonnages required.

The following is a brief introduction to some of the common cold forming methods for stainless steel. The fact that the surface finish survives the forming operation makes the combination of the material and the forming technique cost effective. So elon is wrong about forming stainless steel. 2 3 these researchers performed drawing tests of cylindrical cups made of types 304 and 316 stainless steel.

Unlike carbon steels work hardening rates for stainless steel mean that more severe deformation is possible at slower forming speeds. Figure 1 shows the experimental setup used by takuda. Studies on stainless steel warm forming. Traditionally cold bending is widely used in stainless steel sheet and steel parts.
