PROPRIETARY Carpenter Electrical Iron Heat Treatments

Thermal treatment
Magnetic properties of the fabricated magnetic core parts produced from the mill product can be improved by a thermal treatment. Heat treating temperatures of 730°C (1350°F) or higher should be employed to obtain part uniformity of magnetic properties. With increasing temperature, DC magnetic properties become softer provided no surface contamination of carbon, sulfur, oxygen, or nitrogen is encountered.
The heat treating atmosphere used is a very important factor. Further improvement in DC magnetic properties can be achieved by employing an atmosphere capable of decarburizing and desulfurizing the material. Degree of material purification is also a function of time at temperature.
Heat treating for best DC magnetic properties
Heat charge in a wet hydrogen atmosphere with a dew point of approximately 24°C (75°F) to 850°C (1562°F) and hold at temperature for 2 to 4 hours, then cool at a rate of 100/170°C (180/306°F) per hour to 540°C (1000°F) and at any rate thereafter.
Other atmospheres, including pack anneal, vacuum, dry hydrogen, argon, and forming gas (hydrogen and nitrogen) may be used with a treating temperature in the 730/1180°C (1350/2150°F) range.
Do not use wet hydrogen above 950°C (1740°F).
