  • Typical composition: 1.0-1.5% Chromium and 0.44-0.65% Molybdenum.

• High-Temperature Resistance:

  • Outstanding ability to withstand elevated temperatures, making it ideal for steam and boiler systems.

• Mechanical Properties:

  • Tensile Strength: Minimum 415 MPa.
  • Yield Strength: Minimum 205 MPa.
  • Elongation: Varies depending on size and manufacturing processes.

• Application:

  • Widely used in industries such as oil, gas, power generation, and chemical processing.
  • Common applications include heat exchangers, superheaters, and reheater tubes.

• Manufacturing Standards:

  • Pipes must meet the ASTM A335 standard, ensuring high quality and reliability.
  • Available in various sizes, thicknesses, and dimensions to match specific project requirements.

Advantages of ASTM A335 P11 Pipes:
