Stainless Steel Sheet Bend Radius

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.

Stainless steel sheet bend radius.

You described a rough rule to find a steel s minimum bend radius. 22 gauge 0 030 0 76 mm 0 5 12 7mm. Steel american iron and. Generally speaking the thicker a piece of sheet metal is the wider the internal bend radius will.

We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. 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 5052 or 3003. Recommended minimum bend radii for steel and aluminum.

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. The following tables showing the minimum bend radius allowable in air bending process for aluminum and steel or stainless steel. Maximum dimensions are 2980 x 1200 mm. A general guideline the minimum metal bend radius is approximately equal to the material thickness.

Maximum weight is 40 kg. Some form of analysis may be requried. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Specifing a bend radius from here will help prevent hair line cracks.

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. Category thickness minimum bend bend radius. To keep it simple i also use a 2 mm inside radius. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.

22 gauge 0 030 0 76 mm. Bend radii and k factors for 304 stainless steel sheet metal components share. 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. Steel 304 1 mm thick.

Maximum sheet thickness for aluminum and stainless steel is 6 mm. The minimum bend radius data shown in these charts is measured to the inside of the bend. These dimensions are all in relation to a 90 angle. Hi my machine bending in radius 3 mm k faktor is 0 45 is it correct or not.

Maximum sheet thickness for all other steel is 6 mm. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. Let s say i have a 2 mm thick sheet and i want to bend it. The thickness of the metal.

If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in. Divide 50 by the material s reduction percentage as specified by the material supplier subtract by 1 and then multiply by the plate thickness. Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.
