ASTM A335 Grade P9 Alloy Steel Seamless Tube , For High-Temperature Service

 

 

ASTM A335 Grade P9 Alloy Steel Seamless Tube is a high-quality alloy steel pipe designed for high-temperature applications. It is part of the ASTM A335 standard, which specifies seamless ferritic alloy-steel pipes intended for high-temperature service. Grade P9, specifically, is an alloy containing chromium and molybdenum, which provide excellent strength, oxidation resistance, and thermal stability.

 

 

Key Features:

  • Material Composition:

    • Chromium (Cr): Enhances oxidation and corrosion resistance.
    • Molybdenum (Mo): Improves strength and temperature resistance.
  • Properties:

    • High-temperature strength and durability.
    • Good resistance to oxidation, corrosion, and creep.
    • Excellent weldability and machinability.
  • Applications:

    • Commonly used in power plants, refineries, and petrochemical industries.
    • Ideal for high-pressure and high-temperature environments, such as boilers, heat exchangers, and superheaters.
  • Standards and Specifications:

    • Standard: ASTM A335
    • Grade: P9
    • Type: Seamless
    • Dimensions: Available in various sizes and thicknesses as per customer requirements.
    • Heat Treatment: Normalizing and tempering or other specified treatments for enhanced performance.
  • Mechanical Properties:

    • Tensile Strength: Minimum 415 MPa (60,200 psi).
    • Yield Strength: Minimum 205 MPa (29,700 psi).
    • Elongation: Varies depending on pipe dimensions but ensures flexibility under stress.
