Minimum Bend Radius Steel Sheet

The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.

Minimum bend radius steel sheet.

In general parts should be designed with a minimum 1t bend radius radius matching the sheet thickness for the simplest setup and to ensure we can form the intended geometry. For example if the thickness of the sheet is 1 mm the minimum bend radius should be 1 mm. Thus the smallest radius of any bend in a sheet should be at least equal to the thickness of the sheet. However it is important to know that this is just a broadly applicable rule of thumb you can follow for making bends in steel.

It shall be equal to three times of sheet thickness plus bend radius. 10 carbon content may be bent back on itself in any direction without cracking. Minimum sheet metal flange bend length 3 x sheet thickness bend radius minimum hole diameter guidelines. Bend radii minimum bend sizes.

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. We recommend a minimum bend radius of 1t for all sheet metal parts. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Minimum bend radius chart.

In general mild steel and type 304 stainless sheet can be formed with sharp bends 1t without concern up to 1 8 thick. 1 steels with lower carbon content are easier to weld and form. Below is xometry s minimum bend radius reference table which is based on. Minimum sheet metal flange bend length is required to avoid cracks in the bending area.
