Minimum Bend Radius Stainless Steel Sheet Metal

The minimum inside bend radius is even larger when bending with the grain.

Minimum bend radius stainless steel sheet metal. Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal. If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in. Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.

Recommended minimum bend radii for steel and aluminum. Each and every bend in a piece of sheet metal has a certain minimum internal radius that needs to be taken into account when planning the design of a sheet metal form. 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.

The problem with bending too tightly. The following tables showing the minimum bend radius allowable in air bending process for aluminum and steel or stainless steel. These dimensions are all in relation to a 90 angle. Maximum weight is 40 kg.

Aluminum 5052 or 3003. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. If a piece of material is bent too tightly problems can occur.

A general guideline the minimum metal bend radius is approximately equal to the material thickness. Let s say i have a 2 mm thick sheet and i want to bend it. I can now see that the minimum flange length is 8 5 mm for such a bend so i have to keep it in mind when designing. Table 1 preferred recommended 90 degree bend radii for various sheet metals.

Maximum sheet thickness for aluminum and stainless steel is 6 mm. 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. Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried. 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.

To keep it simple i also use a 2 mm inside radius. Use this document to choose values that are both manufacturable and meet your needs. Maximum sheet thickness for all other steel is 6 mm. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

Maximum dimensions are 2980 x 1200 mm.
