Hastelloy B3 Seamless Nickel Alloy Steel Tube is a high-performance nickel-molybdenum alloy tube specifically designed to offer excellent resistance to hydrochloric acid and other strongly reducing chemicals. Known for their enhanced thermal stability and improved fabricability, these tubes are widely used in harsh chemical environments. ① STANDARD: ASTM B622/ ASTM B829 ...② OD RANGE : 6-257 MM③ THICKNESS RANGE: 1-35 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.
The Hastelloy C2000 seamless nickel alloy steel tube is a high-performance material, designated as UNS N06200 or W.Nr. 2.4675. It's a versatile nickel-chromium-molybdenum alloy uniquely formulated with a controlled copper addition to enhance its corrosion resistance in a wide range of aggressive chemical environments.① STANDARD: ASTM B622 B619...② OD RANGE : 6-257MM③ THICKNESS RANGE: 1-35 MM
Seamless ASTMB622 Hastelloy C22 Nickel Alloy Steel Pipe is a cylindrical hollow component made from a corrosion-resistant nickel-chromium-molybdenum alloy, specifically designed to transport fluids or gases in highly corrosive environments. ① STANDARD: ASTM B622/ASME SB 622 for seamless ASTM B619/ASME SB 619 for welded, ...② OD RANGE : 6-457MM③ THICKNESS RANGE: 1-45 MM
