The K Factor for a 180° bend is going to be meaningless because it s tied to the Outside Setback which approaches infinity as the bend approaches 180° Because of this K Factors are not used to calculate allowances over 174° Instead a hem allowance of 43% of the material thickness is used See our post on Sheet Metal Hems for more

Sheet metal forming processes are those in which force is applied to a piece of sheet metal to modify its geometry rather than remove any material The applied force stresses the metal beyond its yield strength causing the material to plastically deform but not to fail By doing so the sheet can be bent or stretched into a variety of complex shapes

Sheet metal bending is an operation that involves using forces to change the shape of a sheet This is done to achieve the desired form or shape needed for a manufacturing process The external force used alters only the external features of the sheet However parameters of the one type of sheet metal such as length and thickness remain the same
