Steel Plate Bending Radius

In steel between 0 5 and 0 8 in.

Steel plate bending radius.

Bend radii minimum bend sizes. 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.

Grain direction is formed in metal in the direction in which the sheet was rolled at the steel mill. Thick you likely will need to hot form. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Grain direction is not to be confused with surface finishes made by sanding or other finishing operations.

Operation the radius can be near zero for thin sheet metal. 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. It is normally expressed in terms of multiples of the material thickness e g. If the material is 0 5 in.

4 0 5 2. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. 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 see figure 1.

So in this case the minimum inside bend radius is 2 times the material thickness. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Use this document to choose values that are both manufacturable and meet your needs. Note that this is just a rule of thumb.

The most important consideration when bending metal on a brake is the minimum bend radius. Bend allowance calculator tells you the amount of metal to add. Grain direction is often. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.

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 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.
