Steel Plate Bending Radius

Grain direction is not to be confused with surface finishes made by sanding or other finishing operations.

Steel plate bending radius.

In steel between 0 5 and 0 8 in. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. 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. 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.

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. Grain direction is often. Thick you likely will need to hot form.

A simple rule of thumb. And between 0 8 and 2 in. 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 radii minimum bend sizes. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. 4 0 5 2. Plate rolls angle rolls band.

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. Discover all our calculation tools in the calculators section of the top menu.

Use this document to choose values that are both manufacturable and meet your needs. It is normally expressed in terms of multiples of the material thickness e g. Bend allowance calculator tells you the amount of metal to add. Grain direction is formed in metal in the direction in which the sheet was rolled at the steel mill.

Operation the radius can be near zero for thin sheet metal. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. If the material is 0 5 in.
