Explanation

quenching hardened martensitic steel containing about 1% carbon and alloy elements such as Cr, Mo, Co, etc. For example, hard magnetic steel is used to manufacture permanent magnets. magnet steel can be divided into non-alloy steel, tungsten steel, chromium steel, molybdenum steel, cobalt steel, etc. Compared with other permanent magnet material, magnet steel has lower performance, poor temperature stability and serious aging phenomenon. Can be used to make instruments, speakers, hysteresis motor rotors, etc. With the extensive production and application of various permanent magnet material, especially the rare earth permanent magnetic material, magnet steel has been rarely used.
