Bending Stainless Steel Sheet Radius

An air bend force chart or force chart breaks down a number of key components of sheet metal bending in an easy to reference format.

Bending stainless steel sheet radius.

Grain direction is not to be confused with surface finishes. First we must start with the k factor. Hi my machine bending in radius 3 mm k faktor is 0 45 is it correct or not. Measure and mark the bend location along one edge of the stainless steel sheet with the tape measure and awl.

The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. The r10 tools are used to bend u shapes of up to 6 mm for steel and up to 5 mm for stainless steel. See the figures below to determine what the feasible width height ratio is. Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer.

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. If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured. 2 the stainless steel sheet has a strong rebound tendency compared with carbon steel when bending. 3 the percentage of elongation of stainless steel plate is lower than the carbon steel the bending angle of the workpiece r is larger than that of carbon steel or there is the possibility of cracks.

Another way to determine the k factor is by following the rule of thumb. If you re bending 0 020 thick material use a 0 020 radius. The gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick.

Steel 304 1 mm thick. Grain direction is formed in metal in the direction in which the sheet was rolled at the steel mill. We want to know the final length of the detail. However there is a limit to the feasible width height ratio of the u shape.

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. Minimum bend includes minimum closeness of cutout to bend radius cold rolled steel 14 gauge 0 075 1 91mm.
