Coercive force measurements for relay steel

Relay steels that are used in manufacture of such electromechanical devices or their parts as relays should meet specific requirements including coercive force value bellow defined level. Wide spread method of obtaining specific magnetic properties of relay steel is annealing. Is required coercive force value achieved after all the metal treatments and metal finishing?

It can be measured by a Magnetic structurescope (Coercimeter).
