The standard applies specifically to bent components made from flat-rolled steel products. It is crucial for the standard to define the scope of its validity clearly. The steels and semi-finished products it covers are primarily those falling under ICS 77.140.50, which includes flat steel products and semi-products.
For decades, has been the definitive German technical standard used globally to regulate these calculations. It provides the mathematical formulas and correction factors required to determine flat blank lengths accurately. What is the DIN 6935 Standard?
The DIN 6935 standard is a widely recognized specification in the steel industry, outlining the technical delivery conditions for hot rolled steel strip used in cold forming applications. This standard is essential for ensuring the quality and reliability of steel products used in various industries, including construction, automotive, and manufacturing. Din 6935 Standard Pdf
is a German Institute for Standardization (Deutsches Institut für Normung) document that outlines the guidelines for the cold bending of flat-rolled steel. It covers the methodology for calculating the "developed length" (or "flat pattern") of a piece of metal, taking into account the stretching of the material during the bending process. Key Aspects Covered by DIN 6935 Bend Radius ( ): The inside radius of the bend. Bending Angle ( ): The angle of the bend, which can range from 0∘0 raised to the composed with power 180∘180 raised to the composed with power Material Thickness ( ): The thickness of the sheet metal.
DIN 6935 provides a standardized method, but it is important to note that other calculation methods exist: The standard applies specifically to bent components made

When sheet metal is bent, the material on the outside of the bend stretches, while the material on the inside compresses. The —a line within the material that neither stretches nor compresses—shifts towards the inside of the bend. Stretched Length ( Lfcap L sub f ): The total length of the flat part before bending. Leg Lengths ( ): The dimensions of the sides of the bent part. Correction Value ( For decades, has been the definitive German technical
: Defines the minimum distance required between a bend and the edge of the sheet to allow for proper tooling engagement Accessing the Standard
The standard explicitly applies to bent components made from flat steel products, which include plates, sheets, and strips. Its primary areas of use are (Stahlbau) and general mechanical engineering (allgemeinen Maschinenbau). By following these rules, manufacturers can achieve repeatable, high-quality bending results and ensure component reliability.
