Steel Plate Bending Radius

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.

Steel plate bending radius.

The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. 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. Plate rolls angle rolls band. If the material is 0 5 in.

So in this case the minimum inside bend radius is 2 times the material thickness. 4 0 5 2. Grain direction is formed in metal in the direction in which the sheet was rolled at the steel mill. And between 0 8 and 2 in.

Bend radii minimum bend sizes. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. Grain direction is often. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

The most important consideration when bending metal on a brake is the minimum bend radius. A simple rule of thumb. Operation the radius can be near zero for thin sheet metal. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

In steel between 0 5 and 0 8 in. Note that this is just a rule of thumb. Thick you likely will need to hot form. 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. Use this document to choose values that are both manufacturable and meet your needs. Now multiply that answer by the plate thickness. Bend allowance calculator tells you the amount of metal to add.

Discover all our calculation tools in the calculators section of the top menu. In steel between 0 5 and 0 8 in. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.
