Standardize calculations across design engineering and workshop teams.
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.

Standards are living documents. Although a draft revision was proposed and later withdrawn, DIN 6935 will continue to evolve to reflect current industrial practices. The community of users, professional associations, and the NAFS committee will continue to provide feedback and drive the standard's development.
This supplement provides compensating values for various bending angles, radii, and material thicknesses calculated on the basis of DIN 6935. The calculations are precise to four decimal places, while the values in the tables are rounded to two decimal places for practical use.
