In addition to 0.45 % carbon, Thermodur 2383 Supercool exhibits a chemical composition of 1.5 % vanadium, 1.5 % molybdenum, 0.9 % manganese and 0.9 % nickel. It possesses excellent thermal conductivity (44 W/(m⋅K) at 100 °C) as well as good wear resistance, through-hardenability, long-term tempering resistance and high-temperature strength.
As a result of these properties, Thermodur 2383 Supercool is ideal for mould inserts in press hardening tools. These are currently used in the forming of automotive body parts.
In press hardening processes, steels are heated to austenitizing temperature before being transferred to a press tool featuring active cooling. The steel is then quenched and formed simultaneously. This allows ultra-high-strength steels to be formed into complex shapes, enabling replacement of expensive light metal alloys with thinner, stronger steels, an essential factor in the competitive automotive industry.
Specifically, the high thermal conductivity of Thermodur 2383 Supercool, in comparison to conventional hot-work steels such as 1.2343 (AISI H11), 1.2344 (AISI H13) and 1.2367 (X38CrMoV5-3) in quenched and tempered condition, enables enhanced quenching uniformity as well as faster quenching, thereby allowing for reduced cycle times.
*This special steel is available from Deutsche Edelstahlwerke in plate form.
Deutsche Edelstahlwerke (DEW) is one of the world’s leading producers and processors of special steel long products and belongs to the Swiss Steel Group. In the three materials groups – engineering steel, tool steel and stainless, acid and heat resistant steel – Deutsche Edelstahlwerke offers international customers a uniquely wide range of product dimensions, from drawn wire with a diameter of 4.5 mm to open-die forgings with a diameter of 1,100 mm. As a partner with technical competence in steel, Deutsche Edelstahlwerke develops innovative, individual special steel solutions for complex high-tech applications and offers services ranging from steelmaking to extensive steel processing and steel finishing.
Deutsche Edelstahlwerke is the leading producer of long high-grade steel products. The products range from drawn wire with a diameter of 5.0 mm all the way to forged products with a diameter of 1100 mm.
This wide product range makes our offering unique in the world and gives our customers a decisive advantage: with us, they can get everything from a single source.
As one of the world's largest producers of tool steel, we supply exactly the steels that our customers need for their individual products, with properties accurately tailored to the respective application.
Stainless, acid and heat-resistant steels from Deutsche Edelstahlwerke are always in demand when extreme technical requirements are imposed on the material. Because of their outstanding chemical corrosion and mechanical properties, these steel grades are particularly used in the chemical industry, mechanical engineering, the food processing industry, power engineering, medical equipment, traffic engineering and the offshore sector.
Automotive engineering, mechanical engineering and gearbox construction would today be almost inconceivable without high-grade structural steels and anti-friction bearing steels from Deutsche Edelstahlwerke. Made-to-measure processing and service properties are achieved by precise setting of the chemical composition and by special production and test conditions.
Ferro-Titanit is the name of the carbide-alloyed materials of Deutsche Edelstahlwerke produced by powder metallurgy, uniting the properties of steel and cemented carbides.
