PROPRIETARY Chrome Core 13-FM Heat Treatments

Annealing:
Anneal at a temperature of 820°C ± 14°C (1508°F ± 25°F) for 2 to 4 hours. Annealing temperatures above 850°C (1560°F) should be avoided because of potential degradation of the magnetic properties. The cooling rate after the anneal is not critical, although rapid cooling and quenching may induce stresses that impair the magnetic characteristics. Any inert annealing atmosphere such as vacuum, inert gases, or dry forming gas is satisfactory. Attempts to decarburize the alloy using a wet hydrogen atmosphere are not recommended. Similar heat treating practices can be used to soften the alloy for further forming.
Cold working: Can be formed and cold drawn. Cold work will increase the hardness and degrade the magnetic properties. Because it is free machining, will withstand less cold work than non-free machining ferritic alloys and is not recommended for parts produced by large amounts of cold deformation.
