DIN 1624 Standard: A Comprehensive Overview

• Unalloyed composition (carbon content typically between 0.02% and 0.25%).
• Suitability for cold forming (bending, stamping, deep drawing, and profiling).
• Precise dimensional tolerances (thickness and width).
• Surface condition (bright, smooth, often with a protective oil film).

The DIN 1624 standard applies to hot-rolled flat products made of non-alloy steels for cold forming, including:

• It distinguished between "slit edges" (untrimmed) and "sheared/trimmed edges."

This version of the standard covers cold-reduced, mild, unalloyed steel strip. Note that this standard has been largely superseded by DIN EN 10139 in modern engineering.

3. Corporate Archives

Companies that have been in operation for several decades often maintain internal "Standards Libraries." If you work in manufacturing, checking the engineering department's shared drive or physical archives is often the fastest way to locate a PDF of DIN 1624.

The DIN 1624 ensures that the hardware meets specific mechanical thresholds:
