) in the bend area typically decreases, often by approximately , depending on the material and the sharpness of the bend. 3. Compensation Value (
The DIN 6935 standard provides detailed specifications for the design, dimensions, materials, and testing of these components, ensuring that they meet the required performance and safety standards.
The standard establishes standard values, factors, and calculation methods for determining the blank length of bent steel parts. It focuses heavily on the behavior of the material's —the theoretical layer within the metal thickness that neither stretches nor compresses during the bending process.

The full text of DIN 6935, including detailed tables for correction values, is a copyrighted technical document. You can find official versions through the following channels:
Using standard guidelines like DIN 6935 removes guesswork from the manufacturing cycle. ) in the bend area typically decreases, often
Here’s a well-structured, informative text about the that you can use for a website, technical article, or product description.
The flat length is calculated by adding the external dimensions ( ) and subtracting a compensation value ( L=a+b+vcap L equals a plus b plus v The compensation value ( The full text of DIN 6935, including detailed
: It specifies the smallest allowable radii based on steel grade and thickness to prevent cracking. Material Behavior
