Bending Stainless Steel Sheet Metal

Mild steel 1 brake shear slip roll 1 metal forming 1.

Bending stainless steel sheet metal.

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. 2 the stainless steel sheet has a strong rebound tendency compared with carbon steel when bending. Bend radii minimum bend sizes. Scoring and bending.

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. Choose a bend radius that matches your minimum 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.

It is important to make sure that the sheet is properly pushed onto the wipe die. Measure and mark the bend location along one edge of the stainless steel sheet with the tape measure. Making the bend with a sheet metal brake. As a result the wipe die also determines the bend s inner radius.

Bending a brittle metal beyond its limits could cause the metal to snap and break. 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. Determine your minimum bend by measuring the distance from your closest feature i e. Push the clamping leaf handles away from you to raise the clamping leaf.

The slack between the wipe die and the punch plays an important role in getting a good result. Wipe bending or edge bending is another way to bend sheet metal edges. How to bend sheet metal without a brake. A cutout or the edge of your flange to your bend.

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. Mild steel 2 12 ga. Stainless steel 1 14 ga. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched.

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. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. Mild steel 1 16 ga. 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.

Stainless steel 1 20 ga.
