Electromagnetic Stainless Steel (K-M steel)

Electromagnetic Stainless Steel (K-M steel)

Electromagnetic Stainless Steel
(K-M steel)

This material, which has both high corrosion resistance and superior magnetic properties equivalent to those of pure iron, are used in a wide variety of fields as the magnetic material for solenoid valves.

Application examples

  • Iron cores of solenoid valves for pneumatic pressure, hydraulic pressure, water, and refrigerant (used in machine tools, microcomputer-based gas meters, mass flow controller for semiconductor manufacturing equipment, water heaters, air conditioners, refrigerators, and vending machines, etc.)
  • Electromagnetic pumps (Fan heaters, boilers, and drying machines)
