Soft magnetic stainless steel bar K-M31

Product Description


Magnetic core material, which is essential in electromagnetic actuators, is required to have various different properties such as corrosion resistance, magnetic property, electrical resistance, and workability depending on the usage or performance.  



Compared with pure iron magnetic materials:
High corrosion-resistance
High electrical resistance 
To meet processing methods:
Free-cutting types
Cold forgeable types
Compared to general ferrite stainless steel:
Excellent magnetic properties




Fuel injectors, solenoid valve cores,
ABS sensor cores, magnetometric sensors, semiconductor valve stems, 
massflow controller cores
