Roba Metals supplies high-quality High Performance Alloys, also known as superalloys or high-temperature alloys, for applications in sectors including the (petro)chemical industry, energy, furnace construction and mechanical engineering.

Our alloys are flat, low-stress and available from stock, enabling you to produce quickly and efficiently. Thanks to our robust logistics, we serve the whole of the Netherlands, Belgium and Germany with short delivery times.

What are High Performance Alloys?

High Performance Alloys are high-grade stainless steel alloys specially developed for extreme conditions. These include applications involving high temperatures, aggressive chemicals or heavy mechanical stress. Where standard stainless steel grades such as 304 or 316 are no longer sufficient, these alloys provide the solution.

Applications of High-Performance Alloys

High Performance alloys are used in environments where maximum performance and reliability are essential. Examples include environments and applications such as:

  • The chemical industry for tanks, pipes and process components
  • Offshore and maritime applications for piping and supporting structures
  • Aerospace for nickel and titanium alloys and landing gear
  • Semiconductor industry for precision components
  • Defence for armour, structural elements and components
  • Energy and heat for furnaces and heat-resistant components
  • Waste processing and boiler construction for combustion zones and flue gas treatment
  • Mechanical engineering for components subjected to high loads or temperatures
  • Medical industry for implants and prostheses
