Nickel Chromium Nickel-Chromium Alloy Resistance Heating Wire

Product Description

Resistance electric heating wire has strong antioxidant properties, but a variety of gases in furnaces such as air, carbon, sulfur, hydrogen and nitrogen atmosphere, still have a certain impact on it. 

 

Although these heating wires all have had antioxidant treatment, the transportation, winding, installation and other process will cause damage to a certain extent and reduce its service life.

 

In order to extend the service life, customers need to do pre oxidation treatment before using.This methos is to heat alloy elements with have installed completely in the dry air to the temperature  (lower 100-200C than its maximum using temperature), heat preservation for 5 to 10 hours, then cooling slowly with furnace.
