Alloy 31 (N08031, 1.4562) nickel-based alloy is a nitrogen-containing iron-nickel-chromium-molybdenum alloy with properties between super austenitic stainless steels and existing nickel-based alloys. UNS N08031 Alloy 1.4562 Exhaust Pipes are a nickel, chromium and molybdenum grade steel. This grade of Alloy 31 pipes also has additions of both nitrogen and copper. The properties of this alloy pipe are a combination of moderate tensile strength along with high ductility and excellent corrosion resistance. The Nicrofer 3127 hMo UNS S08031 Pipe demonstrates excellent resistance to corrosion in not only sulfuric acid, but also in reducing and oxidizing media. This Alloy 31 n08031 Electro polished Pipes has strong resistance to both corrosion and erosion corrosion, especially in phosphoric acid containing environments.
HT PIPE is one of producer and manufacturer of the Alloy 31 pipes and tubes, we are committed to providing customers with better quality Nickel steel pipes, we provide Nickel steel seamless pipes and welded pipes with wall thickness from sch5 to XXS, and at the same time provide customers with Cutting and customized prefab welding services.
