Bending Stainless Steel Sheet Metal

Choose a bend radius that matches your minimum bend.

Bending stainless steel sheet metal.

For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. 2 the stainless steel sheet has a strong rebound tendency compared with carbon steel when bending. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. Mild steel 1 16 ga.

Mild steel 2 12 ga. Wipe bending or edge bending is another way to bend sheet metal edges. In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend. If you re bending 0 020 thick material use a 0 020 radius.

As this happens you gain a small amount of total length in your part. The slack between the wipe die and the punch plays an important role in getting a good result. Likewise when you are trying to develop a flat pattern you will have to make a deduction from your desired part size to get the correct flat size. Mild steel 1 brake shear slip roll 1 metal forming 1.

When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. Stainless steel 1 14 ga. Bending a brittle metal beyond its limits could cause the metal to snap and break. Determine your minimum bend by measuring the distance from your closest feature i e.

Bend radii minimum bend sizes. As a result the wipe die also determines the bend s inner radius. It is important to make sure that the sheet is properly pushed onto the wipe die. Push the clamping leaf handles away from you to raise the clamping leaf.

3 the percentage of elongation of stainless steel plate is lower than the carbon steel the bending angle of the workpiece r is larger than that of carbon steel or there is the possibility of cracks. A cutout or the edge of your flange to your bend. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance keep in mind that some metals are more brittle than others. 4 due to the high hardness of stainless steel plate with obvious cold work hardening effect therefore the tool steel should be chosen as the punch die and the heat treatment hardness of.

How to bend sheet metal without a brake. How to bend stainless steel sheets marking the bend. Scoring and bending. Stainless steel 1 20 ga.

And not only for its aesthetic function but also for regulations especially in the food sector since when bending a stainless steel sheet even if it has protection if it is marked it not only causes an aesthetic deterioration but also causes a contamination of the bended stainless steel since the ferric particles adhered to the die pass to the bended stainless steel being very deep and sometimes even after a polishing operation of the sheet these particles remain in the stainless.
