Magival®
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 Magivai® grades can be used to advantage in the manufacture of:
- magnetic cores
- solenoid valves
- electromagnetic devices
- flow regulators
- injector components

| The best-known type, finding wide use in the automobile industries and for household electrical apparatus and appliances. | Used in components of magnetic devices where high values of magnetic permeability and low values of coercive force are required. | Its field of application is as for MG1. It is used where a greater resistance to corrosion is required, thanks to its molybdenum content. | Its composition has been developed for applications requiring better magnetic characteristics and high corrosion resistance. These properties are obtained thanks to a low content of interstital elements and a high molybdenum content. | Ferritic Stainless Steel with Mo and Ti characterized by an improved machinability and with a better corrosion resistance than 430F series. |
