Steel Plate Bending Radius

If the material is 0 5 in.

Steel plate bending radius.

Operation the radius can be near zero for thin sheet metal. In steel between 0 5 and 0 8 in. Plate rolls angle rolls band. Bend allowance calculator tells you the amount of metal to add.

It is the smallest inside bend radius that you can place in a piece of material before the tensile forces on the outside of the bend begin to tear the grains in the material apart. So in this case the minimum inside bend radius is 2 times the material thickness. Bend radii minimum bend sizes. The most important consideration when bending metal on a brake is the minimum bend radius.

The most important consideration when bending metal on a brake is the minimum bend radius. This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. And between 0 8 and 2 in.

It is normally expressed in terms of multiples of the material thickness e g. 4 0 5 2. Grain direction is not to be confused with surface finishes made by sanding or other finishing operations. Thick grade 350 and 400 may have a minimum bend radius of 2 5 times the material thickness when transverse bending while longitudinal bending may require a minimum bend radius that s 3 75 times the material thickness.

Note that this is just a rule of thumb. Now multiply that answer by the plate thickness. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. Grain direction is often.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Use this document to choose values that are both manufacturable and meet your needs. Thick grade 350 and 400 may have a minimum bend radius of 2 5 times the material thickness when transverse bending while longitudinal bending may require a minimum bend radius that s 3 75 times the material thickness see figure 1. In steel between 0 5 and 0 8 in.

Discover all our calculation tools in the calculators section of the top menu. A simple rule of thumb. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
