Minimum bend radius 304 stainless steel sheet.

The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Aluminum is less forgiving than cold rolled steel or stainless steel. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried. 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. And by that i mean the cut out prior to bending comes out to the right size. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.

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. Recommended minimum bend radii for steel and aluminum. Divide 50 by the material s reduction percentage as specified by the material supplier subtract by 1 and then multiply by the plate thickness. 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.

Making a custom metal form using sheet metal is a surprisingly delicate process. Specifing a bend radius from here will help prevent hair line cracks. Material bend radii and minimum bend size charts please note. 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.

For thin gauges 063 and less 1 2 the material thickness for simple bends of 90 degrees or less is acceptable. So i am looking for the parameters for 304 ss that will have the same outcome. You described a rough rule to find a steel s minimum bend radius. 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 minimum bend radius data shown in these charts is measured to the inside of the bend. 18 8 type 302 020 063 063 063 063 063 063 063 063 063 025 094 063 063 031. 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.
