FCH1　Fe-Chrome Heating Wire Type 1

Code：FCH1（Fe-Chrome Heating Wire Type 1）

Properties and Applications

Good heat resistance and oxidation resistance, suitable for high temperature use. High temperature strength is small and ferromagnetic. Workability is hard and cold workability is not good. Workability can be improved by warm working (100-300℃).
