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.

• Outstanding corrosion resistance in alkaline and acidic halide-containing media
• Excellent resistance to sulfuric acid, even in highly concentrated form
• Excellent resistance to corrosion and erosion in phosphoric acid media
• Outstanding resistance to surface corrosion and local corrosion in chlorine dioxide bleaching plants in paper production
• Excellent resistance in reducing and oxidizing media as well as in boiling azeotropic nitric acid
• Good workability and weldability
• VdTÜV-certification for pressure vessels with operating temperatures from -196 to 550 °C (-320.8 to 1,022 °F)
• Certification according to ISO 15156/NACE MR 0175 up to level VI for acid gas applications in the oil and gas industry
• ASME approval for pressure vessels up to 800 °F (427 °C)
