Bending Stainless Steel Sheet Metal

Determine your minimum bend by measuring the distance from your closest feature i e.

Bending stainless steel sheet metal.

How to bend stainless steel sheets marking the bend. Measure and mark the bend location along one edge of the stainless steel sheet with the tape measure. 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. Mild steel 1 16 ga.

If you re bending 0 020 thick material use a 0 020 radius. It is important to make sure that the sheet is properly pushed onto the wipe die. 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.

Stainless steel 1 20 ga. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. 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. Mild steel 1 brake shear slip roll 1 metal forming 1.

Bend radii minimum bend sizes. Making the bend with a sheet metal brake. As this happens you gain a small amount of total length in your part. As a result the wipe die also determines the bend s inner radius.

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. 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. Choose a bend radius that matches your minimum bend.

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. Bending a brittle metal beyond its limits could cause the metal to snap and break. Mild steel 2 12 ga. 2 the stainless steel sheet has a strong rebound tendency compared with carbon steel when bending.

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.
