Bending Stainless Steel Sheet Radius

If you re bending 0 020 thick material use a 0 020 radius.

Bending stainless steel sheet radius.

As you bend a stainless steel sheet the bend area cold hardens increasing the amount of pressure required to finish the bend. Maximum sheet thickness for aluminum and stainless steel is 6 mm. Bending is one of the most common sheet metal fabrication operations. Maximum weight is 40 kg.

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. Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal. We bend lots of stainless which in terms of hardness is very similar to mild steel a36 gr50 cq if i were to start folding i would use 125 and a k factor of 45. The force must exceed the material s yield strength to achieve a plastic deformation.

Our bend radius rule of thumb is the minimum radius material thickness. These dimensions are all in relation to a 90 angle. Maximum sheet thickness for corten steel bent products is 4 mm. Maximum sheet thickness for all other steel is 6 mm.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. The minimum bend radius data shown in these charts is measured to the inside of the bend. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Maximum dimensions are 2980 x 1200 mm.

If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured. The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius. 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. This is done through the application of force on a workpiece.

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. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. It just won t really.

The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
