Hot isostatic pressing (HIP) is a manufacturing process, where materials are sintered, combined and compacted at temperatures of approximately 1450°C (2642°F) and gas pressures of up to 200 MPa.
System components within the pressure vessel not only have to be large; being heat-resistant and capable of withstanding rapid changes of temperature is essential.
Plansee manufactures HIP cylinders, support structures and heating assemblies from molybdenum, ML or TZM and offers additional gas supply and rapid cooling components.
Molybdenum and tungsten are both refractory metals and are the perfect choice for high-temperature use.
With their exceptional properties, they are ideally suited for components in the furnace construction industry:
In order to optimize materials for demanding environments, titanium and zirconium are added to strengthen the microstructure of pure molybdenum. Mo-Ti solid solution and Ti-Zr carbides ensure that optimum strengths at temperatures up to 1400°C (2552°F) are achieved.
TZM exhibits superior creep resistance, higher recrystallisation temperature, and improved thermal stability than pure molybdenum.
