DESCRIPTION
Х23Ю5 – is a ferritic iron-chromium-aluminium alloy (Cr content is around 23%) with high resistivity and very good oxidation resistance suitable for temperature applications up to 1400°C.
This alloy has a better life time in sulfur atmospheres than nickel-chromium alloys.
Х23Ю5 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.
