Additive Manufacturing Powder
Additive manufacturing processes offer freedom in design, short lead times and minimised tooling costs. The range of powders for additive manufacturing processes is constantly being expanded and improved to meet the increasing demands on the mechanical properties and corrosion resistance of printed parts in toolmaking, the aerospace industry and the automotive industry.

Alloys with specific physical properties
This product group includes a wide variety of alloys, e.g. soft magnetic Iron-Cobalt alloys for applications in solenoid control valves, but also Iron-Nickel (Cobalt) alloys with temperature-dependent, low thermal expansion for use in measurement and control technology, for glass to metal seals and thermobimetals and also alloys with shape memory effect.

Co-Base alloys
Most cobalt-based alloys contain Chromium. Alloying elements such as Tungsten, Molybdenum, Nickel, Iron, Aluminium and Carbon provide a wide range of properties, e.g. high hardness and resistance to wear and high-temperature corrosion. Fields of application are primarily in the chemical industry, energy technology, aerospace and medical technology.

Cold work tool steels
Cold work steels are mainly used in cold forming tools. Hardness, wear resistance, toughness, compressive strength and fatigue strength are achieved by alloying with Carbon and Chromium, Tungsten, Molybdenum, Vanadium and Manganese. Hardness values of 50 to over 64 HRC are achieved by hardening and tempering the tool components.
-
Corrosion resistant steels
Corrosion resistance is achieved by a chromium content of over 10.5 % by a maximum Carbon content of 1.2 % and increases with higher Chromium and Molybdenium contents. Balanced alloying technology results in different property profiles and austenitic, ferritic, semi-martensitic, martensitic or ferritic-austenitic microstructures. Austenitic steels are generally not magnetisable.
-
Creep resistant steels
High-temperature and creep-resistant steels are used at temperatures up to 650 °C [1202.0°F], are mainly alloyed with Chromium, Molybdenum, Vanadium, Tungsten and Niobium and exhibit high resistance to high-temperature corrosion. Stable precipitations of the alloying elements results in high creep-resistance. The use application of this steel group is closely linked to the development of energy technology.

Engineering steels
Engineering steels are used for a variety of applications throughout the mechanical engineering industry. These include quenched and tempered steels, nitriding steels and high-strength, maraging steels for lightweight construction, as well as case-hardening steels for gear manufacturing and highly stressed plastic moulds.
-
High speed steels
Cutting tools made of High-Speed Steel achieve high hot hardness, wear resistance and fracture resistance at a hardness of over 60 to 67 HRC through hardening and tempering. The main alloying elements are Carbon, Tungsten, Molybdenum, Vanadium and Cobalt. High contents of carbide-forming elements lead to the formation of wear-resistant carbides in the microstructure.
-
Hot work tool steels
Tools for hot forming processes require fracture resistance, hot wear resistance and resistance to thermal fatigue. Tempered 3% and 5% CrMoV steels with a hardness of approximately 35 to 55 HRC fulfil these requirements perfectly. Particularly highly stressed tool inserts are also manufactured from maraging steels of the type Fe-18% Ni-Co-Mo-Ti.
-
Ni-Base alloys
Nickel-based alloys are used as high-temperature and chemically resistant materials. The chemical resistance is primarily determined by the alloying elements Chromium, Molybdenum and Tungsten. Maximum thermal resistance can be achieved by precipitation hardening with Aluminium, Niobium and Titanium.

Plastic mould steels
The requirements for mould steels are more diverse than in any other manufacturing process. Wear resistance, especially when processing fibre-reinforced plastics, and in addition corrosion resistance, machinability, polishability, thermal conductivity and mechanical properties are among the most important criteria.
