Bending Stainless Steel Sheet Metal

When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched.

Bending stainless steel sheet metal.

Mild steel 2 12 ga. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. Choose a bend radius that matches your minimum bend.

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. As this happens you gain a small amount of total length in your part. 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.

Bending a brittle metal beyond its limits could cause the metal to snap and break. 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. Determine your minimum bend by measuring the distance from your closest feature i e. If you re bending 0 020 thick material use a 0 020 radius.

How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools. Mild steel 1 16 ga. How to bend stainless steel sheets marking the bend. Bend radii minimum bend sizes.

Stainless steel 1 20 ga. 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. How to bend sheet metal without a brake. 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 14 ga. 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. Push the clamping leaf handles away from you to raise the clamping leaf. Measure and mark the bend location along one edge of the stainless steel sheet with the tape measure.

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. As a result the wipe die also determines the bend s inner radius. Wipe bending or edge bending is another way to bend sheet metal edges. Mild steel 1 brake shear slip roll 1 metal forming 1.

2 the stainless steel sheet has a strong rebound tendency compared with carbon steel when bending.
