Cobalt magnet steels have high coercive force which makes it possible to maintain strong magnetic fields with relatively short magnets. These alloys must be hardened by drastic quenching in oil to obtain the maximum magnetic properties. This datasheet provides information on composition, physical properties, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: SA-44. Producer or source: Alloy steel mills and foundries.
