UNS N08031/1.4562/Alloy31/X1NiCrMoCu32-28-7 Material Summary
Alloy 31 is a nickel, chromium and molybdenum stainless steel with nitrogen and copper additions. It combines moderate tensile strength and high ductility with excellent corrosion resistance in sulfuric acid, reducing and oxidizing media and has strong resistance to corrosion and erosion corrosion in phosphoric environment.
Typically the alloy has PREN of ≥ 48, which ensure that the resistance to pitting corrosion is high.
Alloy 31 has excellent resistance to localized corrosion in halide media, both pitting and crevice corrosion. It also provides:
• Outstanding resistance to sulfuric acid.
• Excellent resistance to phosphoric acid.
• Good resistance to nitric and nitric/ hydrofluoric acid mixtures.
• Excellent resistance to chlorine dioxide media in the pulp and paper industry.
• Excellent resistance to both oxidizing and reducing media.
• Good resistance to stress corrosion cracking.
• Excellent resistance to general and localized corrosion in Chloridoxid bleaching plants in paper production
• Certification to ISO 15156/MR 0175 to level VI for sour gas applications in the oil and gas industry
• Excellent corrosion resistance in alkaline and acid halide media
• Approval for pressure vessels with operating temperatures from -196 to 550C
• Good processability and weldability
