4) Alloy character:

Ferritic alloys allow to reach process temperatures of 2192 to 2282F,
Corresponding to a resistance temperature of 2372F. All ferritic alloys have approximatively the same basis composition: 20 to 25 % of chromium, 4.5 to 6 % of aluminium, balance being iron. Some of them contain in addition rare earth, as yttrium or silicium. Those alloys having a ferritic structure, we observe, after a maintenance at high operating temperature, an important growth of the grain and a precipitation of chromium carbides at the grain joints level. This induces an increased embrittlement of the resistance, especially when it is come again at ambient temperature.
