Forming Stainless Steel Sheet

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.

Forming stainless steel sheet. Unlike carbon steels work hardening rates for stainless steel mean that more severe deformation is possible at slower forming speeds. At the end of the article we will be discussing different forming methods used with sheet metal. Bright annealed 2r stainless steel sheet without any additional polishing. 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.

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. As you bend a stainless steel sheet the bend area cold hardens increasing the amount of pressure required to finish the bend. Studies on stainless steel warm forming.

We can accommodate a stainless steel blank up to 32 inches in diameter. Pretty much all the common engineering metals are also used in the form of sheets. An example drawing note might read material. These alloys also tend to respond well to cold forming.

Stainless steel sheet 16 gauge 304 2b. The fact that the surface finish survives the forming operation makes the combination of the material and the forming technique cost effective. 2 3 these researchers performed drawing tests of cylindrical cups made of types 304 and 316 stainless steel. Typical automotive skin panels are just 0 65mm thick so 3mm thick is a huge increase in material mass and means the press has to be many times larger to stamp thicker 3mm material.

1 cold bending forming. As the punch rises. Traditionally cold bending is widely used in stainless steel sheet and steel parts. Previous studies by shinagawa and takuda indicate that warm forming of stainless steel sheet reduces martensite formation when forming at elevated temperatures.

Hydroforming stainless steel is a cost effective process that results in a higher quality product than die stamping methods can produce. Figure 1 shows the experimental setup used by takuda. So elon is wrong about forming stainless steel. Typically the rollers are precision ground with a smooth finish.

The following is a brief introduction to some of the common cold forming methods for stainless steel. The rollers used to finish the sheet emboss the surface finish onto the sheet. It should also be noted that austenitic stainless steels can t be heat treated meaning that cold forming may be your only option. Some of them are carbon steel stainless steel copper and aluminium.

In addition elon has specified 3mm thick stainless steel which greatly increases forming tonnages required.
