C276 Alloy Nickel Pipe Hastelloy C276 Nickel Alloy Pipes

Hastelloy C276, also known as Alloy C276 or Nickel Alloy C276, is a corrosion-resistant nickel-molybdenum-chromium alloy designed for exceptional performance in a wide range of severe environments. The following is a detailed description of Hastelloy C276 Nickel Alloy Pipes:

Composition: Hastelloy C276 is composed primarily of nickel, chromium, and molybdenum, with smaller amounts of iron, tungsten, and cobalt. The approximate composition is:

• Nickel: 57%
• Chromium: 16%
• Molybdenum: 16%
• Iron: 5%
• Tungsten: 3%
• Cobalt: 2%

Characteristics:

• Corrosion Resistance: Hastelloy C276 exhibits excellent resistance to both localized and general corrosion in a variety of environments, including oxidizing and reducing conditions. It is particularly resistant to pitting, crevice corrosion, and stress corrosion cracking.
• High-Temperature Strength: The alloy maintains good mechanical properties at high temperatures, making it suitable for use in applications up to 1093°C (2000°F).
• Formability: Hastelloy C276 is readily formed by standard fabrication techniques, including welding, machining, and forming.

Applications: Hastelloy C276 Nickel Alloy Pipes are used in a broad range of industries and applications, including:

• Chemical processing
