VDM® Alloy 31

VDM®Alloy 31 is an iron-nickel-chromium-molybdenum alloy with the addition of nitrogen. The alloy developed by VDM Metals closes the gap between high alloyed austenitic special stainless steels and nickel alloys. VDM® Alloy 31 has proven itself to be suitable particularly in the chemical and petrochemical industries, in ore digestion plants, in environmental and marine engineering as well as in oil and gas extraction.
