Cromaloy 1

Cromaloy 1 is austenitic in character providing good resistance to corrosion up to 1100°C whilst retaining the benefit of ductility when compared with the ferritic Iron/Chrome/Aluminium resistance alloys.

The use of iron in the alloy reduces the density and produces an economical product for use in medium temperature applications. Cromaloy 1 is available in sizes down to 0.08 mm.
