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 see figure 1.

Steel plate bending radius.

Grain direction is often. Bend allowance calculator tells you the amount of metal to add. A simple rule of thumb. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

So in this case the minimum inside bend radius is 2 times the material thickness. Use this document to choose values that are both manufacturable and meet your needs. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. If the material is 0 5 in. Thick you likely will need to hot form. Grain direction is not to be confused with surface finishes made by sanding or other finishing operations.

The most important consideration when bending metal on a brake is the minimum bend radius. In steel between 0 5 and 0 8 in. Note that this is just a rule of thumb. Operation the radius can be near zero for thin sheet metal.

In steel between 0 5 and 0 8 in. 4 0 5 2. Discover all our calculation tools in the calculators section of the top menu. 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.

Grain direction is formed in metal in the direction in which the sheet was rolled at the steel mill. Now multiply that answer by the plate thickness. Bend radii minimum bend sizes. 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.

Plate rolls angle rolls band. The most important consideration when bending metal on a brake is the minimum bend radius. 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.
