Nickel and the Alloys ASTM B829 Ni200/Ni201 Seamless or Welded pipes and tubes
Product Description:
Alloy 625 is a nickel-chromium-molybdenum alloy used for its high strength, excellent fabricability and outstanding corrosion resistance. Service temperatures can range from cryogenic to 980°C (1800°F). Alloy 625 strength is derived from the solid solution strengthening effect of molybdenum and niobium on its nickel-chromium matrix.
Thus precipitation-hardening treatments are not required. This combination of elements also is responsible for superior resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature effects such as oxidation and carburization.
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity.
Nickel pipe/tube is produced in a range of outside diameter, wall thickness and various temper conditions to achieve the required mechanical properties and grain size. The mechanical and dimensional characteristics of our products satisfy the most demanding orders that require tight tolerances.
