ficients can not be determined until thematerial has been brought to a stable state. When the stablecondition had been reached the oil bath was adjusted successivelyto temperatures of approximately 30, 250, and 88°, and normalinduction measurements made. No attempt was made to keepthe temperature… … Fig. i.—Showing normal induction for cast iron at 250 and percentage change in mag-netizing force for a given induction due to 1 degree rise in temperatureC-i, as received C-2, quenched from 1000 C-3, annealed from 900° B
