ETG® 25

Multi-purpose high-strength steel

The multi-purpose high-strength steel

ETG® 25 is a high-strength special steel with excellent machinability, cold forming, bending and welding properties. Its high initial strength as received (similar to strength class 8.8) eliminates your need for heat treatment and elaborates secondary operations, such as straightening, cleaning and discards. 

Why choose ETG® 25

ETG® 25 takes the impossible beyond. By allowing multiple processes, this steel is ideal for complex components – rolling, machining, and welding are possible and rejected volumes are significantly reduced.

High strength

Mechanical values similar to strength class 8.8 EN ISO 898-1 – as delivered. No need for additional heat treatment.

Cold-formability and bendability

Cold-formable and highly bendable without risk of cracking. Reduced production processes and lower component costs. 

Multipurpose capabilities

Well-suited for the production of intricate components involving multiple processes like rolling, machining, and welding, resulting in a notable reduction in rejected volumes.

Climate-neutral steel production

With our Green Steel, we are taking an important step towards climate-neutral steel production. Scrap steel is used as the main raw material and the steel is produced using the electric steel process with energy sources with a low CO2 content. This results in a CO2 footprint well below the industry average.
