Resistalloy International Fecralloy™ Electrical Resistance Steel
Categories: Metal; Electronic/Magnetic Alloy; Ferrous Metal; Stainless Steel; Superalloy

Material Notes: Yttrium addition does not appear in nominal composition. Ferritic stainless steel with aluminum. Available as wire, bar, tube, and strip. Used mainly for electrical elements in both industrial and domestic applications. Industrial applications vary from small laboratory kilns to heavy-duty heat-treatment furnaces under all types of atmospheres. Fecralloy** an Fe-Cr-Al steel containing yttrium is a versatile alloy and is suitable for use over a wide range up to 1300°C. An yttrium addition is the key to its longer high temperature life, having greater oxidation resistance and form stability over other resistance alloys.

Fecralloy is the registered trademark of the UK Atomic Energy Authority (Now AEA Technology, Harwell). Information provided by Resistalloy International Limited.
