Strip FeCrAl 145 | Vojay Group

DESCRIPTION

FeCrAl 145 is a ferritic iron-chromium-aluminium alloy with high resistivity and good oxidation resistance suitable for temperature applications up to 1350°C.

It is alloyed with more than 5% of aluminium, with an addition of about 0.50% niobium, that results in formation of dense, well-adhering, stable layer of aluminium oxide providing excellent resistance to oxidation. Niobium improves high temperature resistance and prevents from too rapid grain growth thereby significantly prolongs the time of utilization, making the material less fragile. As well, FeCrAl 145 is characterized by good creep resistance properties.

FeCrAl 145 is specified for electric furnaces in ceramic, chemical and metallurgic industries, and for all applications where it is necessary to apply a very high temperature of use. Typical applications are: ceramic hotplates, tube elements for dishwashers, radiant (quartz tube) heaters, fans, toasters, irons, burner heads and covers, heating cables and rope heaters, etc.
