Amongst others, our product portfolio includes steels with higher yield point in the tempered state according to DIN EN 10025-6. Colloquially, this steel is also called high-strength constructional steel. Among them, the grades S460Q to S960QL1 are incorporated.
These steel grades have the following advantages
- Excellent bendability and surface quality
- Weldability with good strength and toughness
- Excellent consistency or homogeneous grain structure in a sheet
- High notched impact strength, which offers a good breaking strength
Details on the mechanical values can be found in the table above.
In addition, you can download the complete excerpt of our Quality Guide (QG) for the high-strength constructional steel via the link above.
We can supply the steel grades described as coil, slitted coil, sheets and cutted pieces.
The standard DIN EN 10025-6 replaces the following previous editions.
- DIN EN 10137-2
- Euronorm 137
