Press hardening: Tool steel Thermodur 2383 Supercool

High-strength tool steel for more efficient press hardening

Extended tool life and shorter cycle times in production: Press hardening brings many advantages for the automotive industry - especially in the manufacture of high-strength body parts. The mould insert as an essential element of the mould should therefore consist of a high-strength steel, which at the same time enables an increased cooling speed.

Thermodur 2383 Supercool advantages:
  • High wear resistance
  • Above-average thermal conductivity of 44 W/(mK) at 100° C
  • Good hardenability
  • Resistant to constant high temperatures
  • Increased cycle time - reduced costs


Lightweight construction with steel instead of expensive light metal alloys

Press hardening enables lightweight construction in car body production with steel instead of more expensive light metal alloys. The sheet metal part is hot-formed and heat-treated in a single, combined process step - shaping and adjustment of the mechanical properties take place simultaneously. The thermal conductivity of the tool is of decisive importance for uniform quenching and cycle time and can therefore significantly reduce manufacturing costs.


Producing plastic parts with short cycles: Mold steel MDXtra

The MDXtra tool steel from our Finkl Steel business unit has been specially developed for paintable plastic parts, chrome-plated components or structured surfaces.

The extremely low sulfur content leads to improved polishability. The very good hardenability, which is particularly important for large molds, means only 3 HRC points loss at 1,150 mm thickness.


Advantages of MDXtra
  • Extremely high thermal conductivity
  • Very good hardenability
  • Good polishing properties
  • Excellent weldability
  • Also available as MDXtra SuperHard for even better polishability or remelted MLQXtra for a high gloss finish

All stainless steels for plastic molds: high quality and machinability

Demand for stainless steel plastic molds is increasing more and more. Deutsche Edelstahlwerke offers various steel grades under the All Stainless brand to meet industrial requirements.

Plastic bottles, yoghurt pots, car seats or syringes: Almost every plastic product has its origin in a mould or tool made of stainless steel. The trend in plastic mold construction is toward molds made entirely of stainless steel. However, mold makers can often only machine stainless steels for their purposes with high machining costs. DEW has developed three stainless tool steels for different areas of application in order to meet both the increasing quality demands of industry and the requirements of machinability in the long term.

Tool steel know-how: intermetallic phases as a replacement for critical alloying elements

Only the addition of alloying elements makes steel the versatile material it is. Different carbides and carbide contents give it properties such as strength and wear resistance. However, some of these elements are not always reliably available for geopolitical reasons.

A tool steel made from readily available raw materials

Deutsche Edelstahlwerke has therefore developed a tool steel from readily available raw materials: The Thermodur 2727 IP is based on the alloying elements nickel and aluminium. This makes users less dependent on expensive and resource-critical elements such as tungsten and chromium.


Thermodur 2727 IP uses the intermetallic phase - hence the name suffix IP - nickel aluminide (NiAl) for the special application of aluminium die casting. The performance of the Thermodur 2727 IP is therefore compared with the material 1.2367, which is frequently used for this purpose. Among other things, this material has excellent heat resistance and excellent thermal shock resistance.

Profile of Thermodur 2727 IP
  • 60 % less carbide-forming resource-critical elements
  • Better thermal shock resistance than 2367
  • Higher maximum hardness (up to 55 HRC)
  • Higher permanent tempering resistance
  • Comparable high-temperature strength, high-temperature toughness, thermal conductivity
  • High security of supply
