Stainless Steel Sheet Bend Radius

Steel 304 1 mm thick.
Stainless steel sheet bend radius. Steel american iron and. To keep it simple i also use a 2 mm inside radius. 22 gauge 0 030 0 76 mm 0 5 12 7mm. Specifing a bend radius from here will help prevent hair line cracks.
We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. Generally speaking the thicker a piece of sheet metal is the wider the internal bend radius will. 22 gauge 0 030 0 76 mm. 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.
You described a rough rule to find a steel s minimum bend radius. Bend radii and k factors for 304 stainless steel sheet metal components share. 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. Maximum weight is 40 kg.
The hardness of the metal. Recommended minimum bend radii for steel and aluminum. The thickness of the metal. 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.
Let s say i have a 2 mm thick sheet and i want to bend it. Hi my machine bending in radius 3 mm k faktor is 0 45 is it correct or not. The minimum bend radius data shown in these charts is measured to the inside of the bend. Maximum dimensions are 2980 x 1200 mm.
It is possible to choose other bends if you require but additional lead time and tooling charges may apply. 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. Divide 50 by the material s reduction percentage as specified by the material supplier subtract by 1 and then multiply by the plate thickness. The following tables showing the minimum bend radius allowable in air bending process for aluminum and steel or stainless steel.
Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. Table 1 preferred recommended 90 degree bend radii for various sheet metals. Category thickness minimum bend bend radius. Aluminum 5052 or 3003.
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. These dimensions are all in relation to a 90 angle. A general guideline the minimum metal bend radius is approximately equal to the material thickness. Maximum sheet thickness for all other steel is 6 mm.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. Maximum sheet thickness for aluminum and stainless steel is 6 mm.
