Description
EN 10268 Cold Rolled Steel
EN 10268 is a European standard that specifies cold rolled steel flat products with high yield strength for cold forming. These steels are designed to offer improved mechanical properties while still retaining good formability, making them ideal for structural and automotive applications.
Key Features
- High yield strength
- Cold-rolled precision
- Suitable for cold forming processes
- Improved mechanical performance over EN 10130
- Better surface finish and dimensional tolerance
