The standard, titled "Cold Bending of Flat Rolled Steel," is a critical regulatory document used in mechanical engineering and steel construction to ensure precision when bending flat steel products like sheets and strips. It provides the technical framework for calculating "developed lengths"—the flat size of a part before it is bent—and specifies minimum bending radii to prevent material failure. Key Specifications of DIN 6935

The total blank length ( L ) is the sum of the straight leg lengths plus the neutral axis length in the bend:

The primary objective of DIN 6935 is to define the (or stretched length) of bent steel parts. When metal is bent, the outer surface stretches while the inner surface compresses. This standard helps engineers determine the "neutral fiber"—the layer within the material that remains unchanged in length—to calculate the exact dimensions of the flat blank required for production. Key Specifications Bending Radii (

is a German industry standard titled "Cold bending of flat steel products – Limit deviations for bent parts and formulae for the calculation of the blank length."

) of the workpiece. The total length of the flattened part is not simply the sum of the leg lengths; it is less than the sum due to stretching. L=a+b−Vcap L equals a plus b minus cap V : Developed length (flat pattern length) : Outer leg lengths of the bent part : Compensation Value (also known as bend deduction) How to Calculate the Compensation Value ( The compensation value ( ) depends on the bending angle ( ), the inner bending radius ( ), and the sheet thickness ( ). DIN 6935 provides tables for these values. Generally, the formula for calculating V=2×S−Bacap V equals 2 cross cap S minus cap B sub a (Where Bacap B sub a is the bend allowance).
