Main fields of application of alloy 31

Alloy31 is an iron-nickel-chromium-molybdenum alloy with nitrogen addition. The alloy fills the gap between special alloyed austenitic stainless steels and nickel alloys. Alloy 31 has been proven especially in the chemical and petrochemical industry, in ore extractors, environmental and marine engineering as well as in oil and gas production.
