UNS K92500, 1.4765 Electric Heating Ribbon Spring Strip For Electric Furnance
Iron-Chrome-Aluminum FeCrAl 0Cr25Al5 resistance heating alloy has high maximum service temperature in air up to 1250oC. Longer life permits large surface stress to be applied on the alloy. Lighter weight makes it a more economical resistance heating material than Nichrome. The electric resistivty remains almost constant with varying temperatures. Good yield strength and aging resistance. Outstanding form stability. Greater heat resistance than austenitic stainless steels therefore it is commonly used in the heating applications.
Size dimension range:
Wire: 0.01-10mm
Ribbons: 0.05*0.2-2.0*6.0mm
Strip: 0.05*5.0-5.0*250mm
Bar:10-50mm
