Din 6935 Standard Pdf [2021] May 2026
Please note: DIN 6935 has been withdrawn and superseded by the international standard DIN EN ISO 13722. This report reflects the historical relevance, technical content, and the transition to the current standard.
: For best results, bending should ideally be performed transverse (perpendicular) to the rolling direction of the steel to avoid structural failure. Calculating Developed Length One of the primary uses of DIN 6935 is calculating the stretched length Din 6935 Standard Pdf
The standard provides the mathematical framework and geometric rules for calculating the developed length (unfolded length) of a part before it is bent. This ensures that once the metal is formed, its final dimensions remain accurate despite the physical stretching and compression that occur at the bend.

What is DIN 6935?
Published by the Deutsches Institut für Normung (DIN), this standard specifies the permissible deviations in dimensions and form for bent workpieces made from flat rolled steel. Unlike general geometric tolerances (e.g., ISO 2768), DIN 6935 focuses exclusively on the unique behaviors of bending—such as springback, elongation, and thinning of material at the bend radius.

It emphasizes bending transverse (across) the rolling direction to prevent cracking and achieve higher quality. Bending Angles: Guidelines cover angles from 0° up to 180°. Minimum Bend Length: Recommends a minimum length of at least the bending radius ( ) to ensure consistent results. Modulus Metal Example Calculation
In conclusion, the DIN 6935 standard is a critical specification in the steel industry, outlining the technical delivery conditions for hot rolled steel strip used in cold forming applications. The standard covers the chemical composition, mechanical properties, and surface quality of these steel strips, ensuring that they meet the required quality and reliability standards. By adhering to this standard, manufacturers and users of steel products can ensure the production of high-quality products with consistent properties, which is essential in ensuring the safety and performance of various structures and applications.
The Role of DIN 6935 in Precision Engineering The DIN 6935 standard is a critical technical framework that governs the cold bending of flat rolled steel products within the mechanical engineering and steel construction industries. Its primary function is to provide standardized methods for calculating "developed lengths" (the flat state of a part before it is bent) while ensuring structural integrity by specifying minimum bending radii.
