Minimum Bend Radius 304 Stainless Steel Sheet

For instance right now in solidworks for say 11 ga sheet metal i use a bend radii of 0 005 and a k factor of 0 275 and that seems to work pretty well when i put the flat views on my prints.

Minimum bend radius 304 stainless steel sheet.

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 bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius. For hems a bend of 180 degrees it s highly desirable to use at least one material thickness for most alloys in this size range and essential for aluminum. So i am looking for the parameters for 304 ss that will have the same outcome.

The minimum bend radius data shown in these charts is measured to the inside of the bend. Aluminum is less forgiving than cold rolled steel or stainless steel.

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 tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.

Material bend radii and minimum bend size charts please note. 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. For thin gauges 063 and less 1 2 the material thickness for simple bends of 90 degrees or less is acceptable. Discover all our calculation tools in the calculators section of the top menu.

Specifing a bend radius from here will help prevent hair line cracks. To get the best results a design engineer has to account for many factors such as the end use of the metal form the material the sheet metal is made of plain steel stainless steel etc and the dimensions shape of the final product. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.

Sheet metal bend radii if these guidelines are not followed more research and or 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. You described a rough rule to find a steel s minimum bend radius.
