SLIGHTLY HIGHER ACQUISITION COSTS, SIGNIFICANTLY CHEAPER PRODUCTION
W
hen it comes to choosing the right tool steel, there is often only one criterion in
the foreground: the price. But this is exactly where it pays to take a closer look. The special steel Thermodur E 40 K Superclean from the Swiss Steel Group impressively demonstrates that a supposedly more expensive steel can be a significantly better choice from an overall cost perspective. Thanks to its unique properties, E 40 K Superclean not only offers outstanding performance, but also significant advantages in terms of production efficiency and component service life. Thermodur E 40 K Superclean is a high-
purity tool steel with a microstructure designed to meet the special requirements of modern, highly stressed tools. In the production of E 40 K Superclean, the Swiss Steel Group relies on particularly careful control of the alloy components and an optimised melting process. In order to achieve the best degree of purity, this special steel is remelted using the electroslag remelting process (ESR). The
resulting steel is characterised by an extremely low proportion
of non-metallic
inclusions - a feature known in the industry as ‘superclean’. Total cost of ownership: More expensive
to buy, cheaper to use. Engineers and production managers know using the right material can make all the difference. The E 40 K Superclean impressively demonstrates that a slightly higher material price pays for itself after a short time through increased efficiency and reduced tool downtime. While cheaper steels often lead to production interruptions, higher maintenance costs and a shorter tool life, the Thermodur E 40 K Superclean scores with long-term stable processes and an outstanding tool life. The economic advantages come from
reduced maintenance and downtimes: The E 40 K Superclean reduces the number of maintenance intervals required thanks to its high resistance and resistance to cracking. Less maintenance means more machine uptime and increased overall productivity. Longer tool life: Thanks to its superior
material properties, Thermodur E 40 K Superclean lasts on average up to 50% longer in critical die casting applications than conventional tool steels. This reduces the need for frequent tool changes and saves costs. Improved component quality: The low
susceptibility to cracking and the high surface quality achieved by the Superclean effect contribute to improved component quality. This in turn leads to greater customer satisfaction and reduces rejects.

Developed for demanding applications, Thermodur E 40 K Superclean is used in a wide range of demanding applications in die casting, low pressure die casting, forging, extrusion and plastics processing. It is primarily used where maximum precision and durability are required - for example in the automotive industry, aerospace, plastics processing and mould making. Typical applications include highly
stressed tools in the die casting sector that are prone to thermal shock cracks or have a difficult geometric design. Components that require a high surface quality and wear resistance. Tools for use under extreme conditions, such as high temperatures and dynamic thermal shock loads. Thermodur E 40 K Superclean is also available as Green Steel, allowing users to significantly reduce their CO2
footprint. Thermodur E 40 K Superclean is
an investment in the future of your production. Even if the steel is more expensive to purchase, the long-term savings through increased productivity, reduced downtimes and higher component quality clearly outweigh the costs. With the E 40 K Superclean, you can rely on a tool steel that meets the increasing demands of modern manufacturing processes and, thanks to its outstanding properties, proves to be the more cost-effective solution throughout the entire production process.
