Steel Plate Bending Radius

In steel between 0 5 and 0 8 in.

Steel plate bending radius.

Grain direction is formed in metal in the direction in which the sheet was rolled at the steel mill. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. Discover all our calculation tools in the calculators section of the top menu. And between 0 8 and 2 in.

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. Operation the radius can be near zero for thin sheet metal. So in this case the minimum inside bend radius is 2 times the material thickness. If the material is 0 5 in.

The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. In steel between 0 5 and 0 8 in. Thick you likely will need to hot form. 4 0 5 2.

A simple rule of thumb. Use this document to choose values that are both manufacturable and meet your needs. 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. Bend allowance calculator tells you the amount of metal to add.

The most important consideration when bending metal on a brake is the minimum bend radius. Now multiply that answer by the plate thickness. Grain direction is not to be confused with surface finishes made by sanding or other finishing operations. Note that this is just a rule of thumb.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Grain direction is often. Plate rolls angle rolls band. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.

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. The most important consideration when bending metal on a brake is the minimum bend 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.
