Forming Stainless Steel Sheet

Stainless steel sheet 16 gauge 304 2b.

Forming stainless steel sheet.

The fact that the surface finish survives the forming operation makes the combination of the material and the forming technique cost effective. This makes bending stainless steel with common hand tools difficult and a sheet metal brake is often required although one technique to bend stainless steel using hand tools works well on shorter length bends. Typically the rollers are precision ground with a smooth finish. An example drawing note might read material.

So elon is wrong about forming stainless steel. 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. Hydroforming stainless steel is a cost effective process that results in a higher quality product than die stamping methods can produce. The punch press is basically open type single moving mechanical or hydraulic transmission with a long and narrow table.

The resulting mill rolled finish in the sheet stock is termed 2b as a finish designation for stainless. 1 cold bending forming. Bright annealed 2r stainless steel sheet without any additional polishing. These alloys also tend to respond well to cold forming.

3 this publication is intended to indicate selected processes that make optimum use of stainless steel s forming potential. Pretty much all the common engineering metals are also used in the form of sheets. In addition elon has specified 3mm thick stainless steel which greatly increases forming tonnages required. Another good alternative is duplex stainless steel which combines the properties of austenitic and ferritic stainless steels.

Some of them are carbon steel stainless steel copper and aluminium. We can accommodate a stainless steel blank up to 32 inches in diameter. 2 3 these researchers performed drawing tests of cylindrical cups made of types 304 and 316 stainless steel. Figure 1 shows the experimental setup used by takuda.

Studies on stainless steel warm forming. The rollers used to finish the sheet emboss the surface finish onto the sheet. The following is a brief introduction to some of the common cold forming methods for stainless steel. Stainless steel sheets are cut into blanks then placed in the hydroforming press one at a time over a punch.

Previous studies by shinagawa and takuda indicate that warm forming of stainless steel sheet reduces martensite formation when forming at elevated temperatures. As you bend a stainless steel sheet the bend area cold hardens increasing the amount of pressure required to finish the bend. Unlike carbon steels work hardening rates for stainless steel mean that more severe deformation is possible at slower forming speeds. It should also be noted that austenitic stainless steels can t be heat treated meaning that cold forming may be your only option.
