Nickel 201 Seamless Nickel Alloy Steel Tube is a high-purity, low-carbon nickel alloy tube known for its excellent mechanical properties, corrosion resistance, and thermal conductivity. These tubes are ideal for use in chemical processing, electronics, and marine applications where high performance and purity are essential. ① STANDARD: ASTM B161/ ASTM B163/ASME SB161/ASME AB163② OD RANGE : 6-257 MM③ THICKNESS RANGE: 1-35 MM
Seamless Incoloy 825 Nickel Alloy Steel Pipe is a high-performance piping product made from Incoloy 825 (a registered trademark of Special Metals Corporation), an austenitic nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium.It is a seamless pipe, meaning it's manufactured without a welded seam, providing superior structural integrity, especially under high pressure and temperature applications.The alloying elements provide broad resistance to a wide range of corrosive environments:• Chloride-Ion Stress-Corrosion Cracking: High nickel content provides excellent resistance.• Pitting and Crevice Corrosion: Enhanced by the molybdenum content.• Reducing Agents and Acids: Nickel, molybdenum, and copper provide outstanding resistance to agents like sulfuric acid and phosphoric acid.• Oxidizing Agents: Chromium confers resistance to oxidizing substances like nitric acid.• Intergranular Corrosion: The titanium addition, combined with appropriate heat treatment, stabilizes the alloy, making it resistant to intergranular attack, even after welding.① STANDARD: ASTM B163 ASTMB423 Seamless Superheater, Condenser, Hydraulic, Boiler and Heat-Exchanger Tubes② OD RANGE : 6-457 MM③ THICKNESS RANGE: 1-45 MM
Seamless UNS N08020 Nickel Alloy Steel Pipe refers to a high-performance corrosion-resistant alloy pipe, commonly known as Alloy 20 or Carpenter 20, is a nickel-iron-chromium austenitic alloy designed primarily for superior corrosion resistance in harsh chemical environments, particularly sulfuric acid. It is not a traditional carbon or low-alloy steel but a high-performance nickel-based superalloy with iron as a significant component (typically 32-46%). The "nickel alloy steel" designation in your query likely refers to its classification as a nickel-chromium-iron alloy used in steel-like piping applications. This material is stabilized with niobium (columbium) to prevent sensitization and intergranular corrosion, making it ideal for general corrosive service.Alloy 20 seamless pipes are produced under the ASTM B729 specification (or its ASME SB729 boiler code equivalent), which covers seamless, cold-worked, or hot-finished pipes and tubes in UNS N08020, N08026, and N08024 grades. These pipes are furnished in a stabilized-annealed condition unless otherwise specified.
UNS N08031 Seamles Nickel Alloy Steel Pipe are high-performance nickel-based alloy tubes known for their exceptional corrosion resistance, strength and durability in demanding environments. ① STANDARD: ASTM B622/ ASTM B829 ...② OD RANGE : 6-457 MM③ THICKNESS RANGE: 1-45 MM
