Bending Stainless Steel Sheet Radius

Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer.

Bending stainless steel sheet radius.

In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. Minimum bend includes minimum closeness of cutout to bend radius cold rolled steel 14 gauge 0 075 1 91mm. If you re bending 0 020 thick material use a 0 020 radius.

If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured. However there is a limit to the feasible width height ratio of the u shape. The r10 tools are used to bend u shapes of up to 6 mm for steel and up to 5 mm for stainless steel. The gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force.

First we must start with the k factor. Another way to determine the k factor is by following the rule of thumb. Grain direction is not to be confused with surface finishes. 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.

For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. Bend radii and k factors for 304 stainless steel sheet metal components share. Place a second bend mark on the edge of the stainless steel sheet parallel to the edge you just marked. 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.

Measure and mark the bend location along one edge of the stainless steel sheet with the tape measure and awl. Bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal. 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. 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.

Grain direction is formed in metal in the direction in which the sheet was rolled at the steel mill. Hi my machine bending in radius 3 mm k faktor is 0 45 is it correct or not. 2 the stainless steel sheet has a strong rebound tendency compared with carbon steel when bending.
