Most of our experience is in the processing of ultra-modern metals ranging from those that are creep-resistant (> 700 °C) to those that are extremely tough at subzero temperatures (–196 °C). We are actively involved in the international development of high-chrome, high-nickel and new complex alloys for applications in extreme conditions. Nickel-based alloy 625 as well as newly developed high-alloy 9–12% Cr steels for thick-walled castings meet the requirements of the entire product range of cast parts for USC and AUSC technologies in applications ranging from 600 °C to > 700 °C.
For applications in the oil, gas, offshore, hydro-power and wind energy industries, we supply a wide range of materials with emphasis on a combination of high strength, toughness at low temperatures and good weldability. The materials have been subjected to fracture-mechanics testing and have been officially certified for offshore applications.
We provide tailor-made material development services, casting designs and processes based on individual customer requirements or in collaborative projects with our customers.
Metallurgy, solidification, heat treatment and welding are key issues that must be considered in the development of new and complex steel grades. This development is conducted using empirical testing and thermophysical simulation.
Simulation and thermophysical modeling
Material and process development has changed from an engineering approach to one that combines scientific and empirical data. The interaction of materials and processes is taken into account in modeling, simulation and experiments. Process limits must be expanded in order to optimize material properties for specific requirements of the design.
Specific properties and interactions are taken into account such as complex geometries, thick and thin walls and masses for the key processes of melting, casting, solidification, forming and heat treatment.
A combination of different tools, methods and experiments provides the necessary information in the development of new materials and processes for their production. This has led to a new level of networking, not only among the members of the foundry engineering department and its customers, researchers and universities, but also in the fields of modeling and software solutions.
