Deutsche Edelstahlwerke (DEW) is accelerating the development of its steel solutions for applications such as electric mobility, wind power and fuel cells.
The company claims that it designs and produces its steel solutions in a resource-friendly and future-oriented manner, starting with the selection of steel scrap and relying upon 100% renewable energy.
According to DEW, it produces its Green Steel exclusively in an electric arc furnace and emits only 107kg of CO2 emissions per one ton of crude steel produced. The global average is 1,850 kg of CO2.
DEW uses the term 'green steel' for when the products are in production and 'blue steel' for when they are in use. Where the latter is concerned it promotes the use of eco-friendly steels for sustainable technologies, such as e-mobility and wind energy.
The company claims that its Blue Steel is an indispensable material for the production, transportation and storage of hydrogen. Components such as pipes, tubes, nozzles and injection systems in fuel cells come into direct contact with hydrogen and must be suitably resistant. Rust, acid and heat-resistant steels with a high nickel content are claimed to be particularly suitable for this purpose. In addition to austenitic steels, DEW offers Acidur® 4435 as part of its Blue Steel portfolio.
High wear and fatigue resistance, high toughness and homogeneity: DEW claims that its blue steel is used in the production of wind turbines because of its high wear and fatigue resistance, its high toughness and homogeneity. According to DEW, the gears, bearings and mounting elements for the rotor blades of wind turbines have to withstand high speeds under full load and abrupt stress from gusts. The company's heat-treated Carbodur® 6587 is used for rings, drive components and gearbox parts, and the higher alloyed rolling bearing steel Durapur® 3520 is used for bearings.
DEW claims that the automotive industry demands high-performance materials that are robust and lightweight and believes that its alloy design and hot forming and heat treatment processes simultaneously optimize the toughness and strength of its steels. The company's 'blue steel' for the e-mobility sector is said to offer a high level of process reliability and includes Bainidur® steels and the high aluminium alloyed Aludur® .
• The Swiss Steel Group (formerly SCHMOLZ + BICKENBACH Group) is leading global provider of individual solutions for the special long steel products sector. It is a leading manufacturers of tool steel and non-corrosive long steel and one of the two largest companies in Europe for alloyed and high-alloyed quality and engineering steels. The company employed more than 10 000 people and owns production and distribution companies in more than 30 countries on five continents.
