Bend allowance is the amount of metal to be added to the total layout. The most important considerations when bending metal is the min. bend radius. When bends are made smaller than the required min. radius, metal will crack at the outside heel of the bend.(plate) Automotive & Heavy Duty Muffler Clamps, U Bolts, Stainless MILD STEEL Recommended Bend Allowance American (steel) On a round bend u-bolt, the bend radius is a function of the centerline width and causes few problems with material integrity. On a square bend or v-bolt, the radii may be a function of the mating member of the joint. A large radius (1.5 x the wire diameter) creates less deformation at the radius during the forming operation than a small radius.(plate) Bend Allowance Calculator - CustomPart.Net(steel) The bend allowance and bend deduction are two measures that relate the bent length of a piece of sheet metal to the flat length. The bend allowance describes the length of the neutral axis between the bend lines, or in other words, the arc length of the bend. Therefore, the bend allowance added to the flange lengths is equal to the total flat MILD STEEL Recommended Bend Allowance American
