UNS N02200 Nickel Alloy Seamless Bright Surface Tube
UNS N02200 Nickel Alloy Seamless Bright Surface Tube
UNS N02200 alloy seamless bright finish tubing is a high-quality, seamless tubing made from pure commercial nickel (Nickel 200) with a bright, reflective finish. This tubing typically meets standards such as ASTM B163 and offers excellent corrosion resistance, particularly against alkaline solutions and distilled water. Due to its mechanical strength and durability, it is widely used in industries such as chemical processing, heat exchangers, and food processing.
What is the annealing temperature for Nickel 200 alloy?
1300°F
Nickel 200 alloy can be formed using a variety of hot and cold working processes. The alloy can be hot worked between 649°C (1200°F) and 1232°C (2250°F), with heavy forming temperatures exceeding 871°C (1600°F). Annealing temperatures range from 704°C (1300°F) to 871°C (1600°F).

Key Features and Properties
Material: This alloy is pure commercial nickel, designated UNS N02200 or Nickel 200.
Construction: Seamless tubing, meaning it is manufactured without welds, enhancing its pressure resistance and leak resistance.
Surface Finish: "Bright finish" refers to the bright annealing or polishing achieved after the manufacturing process, resulting in a smooth, corrosion-resistant, and aesthetically pleasing surface.
Corrosion Resistance: It is highly resistant to reducing chemicals, dry fluorine, and especially alkaline substances, making it ideal for handling corrosive materials such as caustic soda.
Mechanical Properties: It exhibits excellent tensile strength, ductility, good thermal and electrical conductivity, and magnetostrictive properties.
Applications
Chemical Processing: It handles varying concentrations of caustic soda, dry chlorine, and other chemicals.
Heat Exchangers and Condensers: Its corrosion resistance and thermal properties make it an ideal choice for these components.
Food Processing: Due to its durability and inertness, it can be used in food processing equipment.
Other Industries: It can also be used in electronics, fiber production, and warehousing and transportation.
