Forging Steel – Get the best out of your material
Forging is your ideal choice of processing for products with the best mechanical properties. Thanks to the expertise of our partners, your product is shaped near to its final state during the forging process which guarantees a close-to-shape work piece. This ensures a high material usage and a lowered subsequent machining time. Near-net shape forgings can achieve up to 90% material usage, thus making forged goods a viable choice – economically and ecologically.
We are experts with over 50 years of experience with regards to forged goods. We can help you identify your needs and provide you with the right solutions for your product.
The forging process
Bringing steel into shape – the hot forging process
During the forging process, ingots or pre-forged bars are reheated to temperatures near two-thirds of the melting point of steel. This makes the material malleable and allows the forge masters to bring steel into shape.
This process is called thermo-plastic deformation, during which the underlying grain and texture of the material are reformed and lead to unrivalled mechanical properties. The deformation of the material leads to a fine grain structure, leading to a tough and ductile material response.
During the forging process, the material cools down and needs to be reheated, often multiple times for one part. Experienced forge masters can tell by the color of the glow whether the material is still hot enough for processing.
After forging, the material is subject to thermal treatment. This process ensures that the steel is in the right state – ferrite, austenite or martensite, and sometimes even multiple phases (for instance in Duplex who features austenite and ferrite) of them depending on the composition and the required properties. The latter depend on the sequence of heating and cooling and the rates of temperature change – Processes that the producers must master and that require special equipment for different cases and sizes.
Clearly, forging and thermal treatment are complex matters and require years of expertise and mastery to craft a high-quality product. That is why we only work with qualified and audited suppliers!
