    P91 Chrome Moly Pipe Cold Drawn Alloy Steel Seamless Pipe For High-Temperature Service

    P91 Chrome Moly Pipe is a cold drawn alloy steel seamless pipe renowned for its excellent mechanical properties and superior performance in high-temperature environments. The material is particularly favored in industries requiring durability and resistance to creep, oxidation, and thermal fatigue. This article details the material specifications, chemical composition, mechanical properties, key features, equivalent grades, and applications of P91 pipes.


    Material

    P91 alloy steel is a modified 9Cr-1Mo steel with added elements like vanadium, niobium, and nitrogen to improve strength and creep resistance. It is primarily used in high-temperature and high-pressure environments such as power plants and petrochemical industries.


    Specification

    • Material Grade: P91 (ASTM A335 P91)
    • Type: Cold Drawn Seamless Pipe
    • Manufacturing Process: Hot Worked, followed by Cold Drawing for improved dimensional accuracy and surface finish
    • Standards: ASTM A335, ASME SA335

    Chemical Composition

    Element C (%) Mn (%) Si (%) P (%) S (%) Cr (%) Mo (%) Ni (%) V (%) Nb (%) N (%)
    Content 0.08-0.12 0.3-0.6 0.2-0.5 ≤0.02 ≤0.01 8.0-9.5 0.85-1.05 ≤0.4 0.18-0.25 0.06-0.10 0.03-0.07

    Mechanical Properties

    Property Value Test Condition
    Tensile Strength (MPa) 585 - 740 Room temperature
    Yield Strength (MPa) ≥ 415 Room temperature
    Elongation (%) ≥ 20 Room temperature
    Reduction of Area (%) ≥ 30 Room temperature
    Hardness (HB) ≤ 200 Room temperature
    Creep Rupture Strength High, suitable for >593°C Long term high-temperature exposure

    Key Features

    • High-Temperature Strength: Excellent resistance to creep and rupture at temperatures up to 600°C.
    • Corrosion Resistance: Chromized surface and alloy elements provide good oxidation and corrosion resistance.
    • Durability: Superior strength and stability under cyclic temperatures enhance pipe life.
    • Seamless Construction: Eliminates weld joint defects ensuring uniform mechanical properties.
    • Dimensional Accuracy: Cold drawing process improves surface finish and tightens tolerances.
