Stainless Steel Sheet Bend Radius

There are a two major factors that affect how tight you can make the internal radius of a bend in a piece of sheet metal.

Stainless steel sheet bend radius.

Steel american iron and. Maximum dimensions are 2980 x 1200 mm. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. These dimensions are all in relation to a 90 angle.

The following tables showing the minimum bend radius allowable in air bending process for aluminum and steel or stainless steel. The thickness of the metal. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Category thickness minimum bend bend radius.

The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. Maximum sheet thickness for aluminum and stainless steel is 6 mm. Specifing a bend radius from here will help prevent hair line cracks. Steel 304 1 mm thick.

Table 1 preferred recommended 90 degree bend radii for various sheet metals. In a previous bending basics article you mention a material s tensile reduction percentage used for calculating the minimum inside bend radius of various metals. A general guideline the minimum metal bend radius is approximately equal to the material thickness. 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.

Divide 50 by the material s reduction percentage as specified by the material supplier subtract by 1 and then multiply by the plate thickness. Maximum sheet thickness for all other steel is 6 mm. Maximum weight is 40 kg. The hardness of the metal.

I have a sheet metal bending table for most gages of sheet metal but not many for ss which is why i was asking this forum. If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in. Let s say i have a 2 mm thick sheet and i want to bend it. 22 gauge 0 030 0 76 mm 0 5 12 7mm.

22 gauge 0 030 0 76 mm. The minimum bend radius data shown in these charts is measured to the inside of the bend. You described a rough rule to find a steel s minimum bend radius. 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.

Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. Recommended minimum bend radii for steel and aluminum. To keep it simple i also use a 2 mm inside radius. Bend radii and k factors for 304 stainless steel sheet metal components share.

We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. Some form of analysis may be requried. Generally speaking the thicker a piece of sheet metal is the wider the internal bend radius will.
