What is the demagnetization temperature of soft magnetic material 430F?
Ferritic stainless steel solid solution, the temperature below 900 DEG C group had no obvious change, the hardness increase with the change of temperature slow; 900 DEG recrystallization, the hardness decreased significantly after heat treatment at 475 DEG C; the precipitates increased, the hardness increases, the corrosion resistance of a serious decline, that there were 475 C brittle the phenomenon of.
430F steel is ferritic stainless steel, generally treated by solid solution treatment. If the surface needs a certain hardness, it can be treated by chemical heat treatment or work hardening.
It is recommended to use demagnetization machine to eraseHigh temperature demagnetization, temperature control will collapseThe average Curie temperature is more than 300 degrees80-100 ferrite FeCrCo degrees 680 degrees 860 degrees alnico NdFeB 380-450
