Description: UgiPerm™ 12FM is a 12% chrome ferritic stainless with improved magnetic properties designed for use in electro-injectors, valves and many other applications. The grade was developed for magnetic applications requiring a very low coercive magnetic field (Hc) and a very high permeability. UgiPerm™ 12FM has a high level of electrical resistivity that shortens activation time when used in pulse mode. It offers excellent magnetic properties with superior corrosion resistance no offered by iron alloys. Applications: Solenoid valves, fuel injectors, irrigation valves, magnetic sensors, magnetic brakes, and electro-mechanical devices. Magnetic Properties (Heat Treatment): Uniformly heat at 800°/900°C (1470°F/1650°F) for 2 hours, then cool to 500°C (930°F) at a rate of 50°C (120°F) per hour. The cycle should be done in a dry hydrogen or vacuum atmosphere to prevent oxidation. Information provided by Schmolz + Bickenbach |
