Din 6935 Standard Pdf !new! Review
Please note: DIN 6935 has been withdrawn and superseded by the international standard DIN EN ISO 13722.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.
4.2 Implications for Industry
- Legacy Drawings: Engineers encountering drawings referencing DIN 6935 must interpret tolerances based on that standard, not current ISO standards, unless a contract states otherwise.
- PDF Availability: As a withdrawn standard, DIN 6935 is
4. Material requirements
- Minimum elongation, tensile strength, and yield strength before forming.
- Chemical composition limits (C, Mn, P, S) to ensure bendability.
4.1 Current Status
DIN 6935 is no longer valid for new designs. It has been replaced by DIN EN ISO 13722 (Metallic materials — Sheet and strip — Determination of the plastic strain ratio). Din 6935 Standard Pdf
Note on Replacement: While ISO 13722 is the official successor regarding testing methods and documentation, many practical workshop tables regarding minimum radii are now found in DIN 6930-2 (General tolerances for welded constructions) or industry-specific standards. Please note: DIN 6935 has been withdrawn and
Why is DIN 6935 Important?
When you bend a piece of sheet metal, the outside of the bend stretches, and the inside compresses. The neutral axis (where no stretching or compression occurs) shifts inward. DIN 6935 provides a scientifically validated method to locate that neutral axis using the K-factor. the outside of the bend stretches
Without this standard, your CAD software’s default unfolding might be off by several millimeters, leading to scrap material. Using the DIN 6935 method guarantees that your flat pattern will result in a finished part that meets the required dimensional tolerances.
Understanding DIN 6935: The Key Standard for Flat Rolled Steel Bending
In the world of sheet metal fabrication and structural engineering, precision and consistency are non-negotiable. The DIN 6935 standard serves as the definitive German (and widely adopted European) guideline for the bending of flat rolled steel products. Accessing the official DIN 6935 Standard PDF is essential for any quality assurance or production department working with bent steel components.
8. Tables and annexes (informative)
- Minimum bending radii for various steel grades and thicknesses.
- Springback values for common angles (e.g., 90° bends).
