1. K. S. Magnet steel has an extremely large coercive force, its intensity of residual magnetism is also considerably larger than that of ordinary tungsten steels.
2. The area of the hysteresis loop of K. S. magnet steel is very large.
3. K. S. magnet steel, when quenched, is mechanically very hard, and has a very fine microstructure.
4. The residual magnetism of K. S. magnet steel does not appreciably diminish by a prolonged heating at 100°C over several ten hours.
5. 850 repeated falls of the steel bar from a height of one metre on a concrete floor causes only a diminution of magnetisation by 6 percent of its initial value.
6. K. S. magnet steel is specially suited for short bar magnets.
