Magival® is a range of ferritic stainless steels, with a high degree of machinability, designed for magnetic applications where there are requirements for:

  • High permeability
  • Low coercive force
  • High machinability

Carefully controlled chemical analysis and sophisticated working processes create a ferritic structure which is highly sensitive to variations in a magnetic field. This avoids the need for expensive heat treatment by the user after machining. Due to their extreme ease of magnetization and demagnetization, the Magival® grades can be used to advantage in the manufacture of:

  • Magnetic cores
  • Solenoid valves
  • Electromagnetic devices
  • Flow regulators
  • Injector components
