Bending Stainless Steel Sheet Radius

Another way to determine the k factor is by following the rule of thumb.

Bending stainless steel sheet radius. If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured. 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. If you re bending 0 020 thick material use a 0 020 radius. We want to know the final length of the detail.

2 the stainless steel sheet has a strong rebound tendency compared with carbon steel when bending. First we must start with the k factor. See the figures below to determine what the feasible width height ratio is. 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. Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. Grain direction is not to be confused with surface finishes.

Grain direction is formed in metal in the direction in which the sheet was rolled at the steel mill. Bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal. Measure and mark the bend location along one edge of the stainless steel sheet with the tape measure and awl. Place a second bend mark on the edge of the stainless steel sheet parallel to the edge you just marked.

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. Steel 304 1 mm thick. 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. 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.

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. Minimum bend includes minimum closeness of cutout to bend radius cold rolled steel 14 gauge 0 075 1 91mm. However there is a limit to the feasible width height ratio of the u shape.
