FeCrAl H - is a ferritic iron-chromium-aluminium alloy (Cr content is around 27%) with high resistivity and good oxidation resistance suitable for high temperature applications up to 1400°C.
Being alloyed by more than 6% of aluminum and around 2% of molybdenum FeCrAl H ensures excellent surface oxide properties, which gives good protection in vacuum, in different corrosive environments as well as in atmospheres with high carbon and sulphur rate. The unique combination of excellent oxidation properties and form stability contributes to long element service life.
FeCrAl H is specied for such applications as: hightemperature industrial and laboratory furnaces for heat
treatment, furnaces for electronic industries, diffusion furnaces, resistance elements, radiant (quartz tube) heaters, ceramic kilns, etc.
