With the new ETG®25 steel, the Swiss Steel Group has developed an innovative solution that not only reduces costs, but also significantly increases efficiency in parts production. According to Swiss Steel, this high-strength cold heading steel sets new standards as it requires no additional heat treatment and therefore simplifies production processes. ETG®25 offers considerable advantages, particularly in industries such as the automotive sector, mechanical engineering and electromobility.
One of the outstanding properties of ETG®25 is that heat treatment is no longer necessary to achieve the required strength. Swiss Steel emphasizes that the steel offers mechanical values that correspond to strength class 8.8 according to EN ISO 898-1 even in its delivery state. This means:
- Shorter production times: Fewer steps in the production process save valuable time.
- Fewer rejects: Optimized material properties ensure greater process stability.
- Lower energy costs: Dispensing with energy-intensive processes reduces energy consumption.
“Our customers benefit from significant cost savings and greater process stability. ETG®25 saves time and resources - two decisive factors in modern industrial production,” says a spokesperson for the Swiss Steel Group.
Top performance without compromise
According to Swiss Steel, the new steel offers an exceptional combination of strength and versatility. ETG®25 is not only cold formable, but also bendable, machinable and weldable. These properties make it ideal for the production of complex components. Tests also show excellent resistance to hot cracking: even in stress tests over 8,000 cycles at 650 °C, the steel performed better than conventional materials.
Another highlight is the material's low residual stress, which ensures high dimensional stability during machining - a decisive advantage in the production of precision parts.
Practical examples show impressive results
According to Swiss Steel, practical applications confirm the advantages of ETG®25:
- shorter production times: One mechanical engineering project recorded time savings of up to 30%.
- longer service life: cold-formed threaded bolts made of ETG®25 showed significantly increased fatigue strength.
- cost savings in electromobility: the production of shafts for electric vehicles could be made 20 to 30 % cheaper by using ETG®100, a related steel.
Focus on sustainability: “Green Steel” option
Swiss Steel emphasizes that ETG®25 is also a convincing environmentally friendly alternative. By using recycled steel scrap in the electric arc furnace process, CO₂ emissions are reduced by up to 94% compared to conventional blast furnace processes. “Sustainability and innovation go hand in hand for us. ETG®25 is an example of how we are actively shaping the future of the steel industry,” emphasizes Frank Koch, CEO of the Swiss Steel Group.
Technical highlights of ETG®25
