ALLOY STEEL FORGINGS SA336 F5N TUBESHEET HEAT EXCHANGER PARTS

 

The SA336 F5N material is a type of forged alloy steel typically used in high-temperature and pressure applications, such as in boilers, pressure vessels, or heat exchangers.A tubesheet is a thick plate that contains holes to hold the tubes of a heat exchanger or boiler. It serves as a critical component in ensuring the integrity and efficiency of these systems, by keeping the tubes fixed in place while allowing for the transfer of heat.

Key points about ASME SA336:

  1. Material Composition: The ASME SA336 specification covers several grades of alloy steel used in high-temperature applications. Some of the most commonly used grades under this specification include:

    • Grade F1: Carbon-Manganese-Silicon alloy.
    • Grade F5: Chromium-Vanadium alloy.
    • Grade F9: Chromium-Molybdenum-Vanadium alloy.
    • Grade F11: Chromium-Molybdenum alloy.
    • Grade F22: Chromium-Molybdenum alloy (more resistant to oxidation).

    These alloys are specifically designed to resist heat, pressure, and corrosion at elevated temperatures.

Common Grades:

  • SA336 F5N: A common grade in the SA336 standard, used in heat exchangers, pressure vessels, and other high-temperature applications.
  • SA336 F9: Known for its improved resistance to oxidation and creep at higher temperatures, commonly used in more demanding power generation environments.

ASME SA336 Grade Table

GradeAlloy CompositionTypical ApplicationsProperties
F1Carbon-Manganese-SiliconPressure vessels, steam boilers, and heat exchangers at temperatures up to 900°F (480°C).Moderate strength, good toughness and weldability at high temperatures.
F5Chromium-Vanadium (0.5–0.75% Cr, 0.1–0.2% V)Steam turbines, heat exchangers, gas turbines, and high-temperature piping systems.Improved resistance to creep, oxidation, and high-temperature fatigue.
F5BChromium-VanadiumHigh-temperature structural components.Similar to F5 but with enhanced properties for better high-temperature performance.
F9Chromium-Molybdenum-Vanadium (0.5–0.6% Cr, 0.25–0.35% Mo, 0.1–0.15% V)Power plant pressure vessels, heat exchangers, boilers, turbines, and pipelines.Higher creep strength and oxidation resistance, suitable for higher-temperature applications (up to 1050°F or 565°C).
F11Chromium-Molybdenum (1–1.5% Cr, 0.5–0.8% Mo)High-temperature piping, boilers, pressure vessels, and heat exchangers.Offers good strength and resistance to thermal fatigue and corrosion. Commonly used in fossil-fuel power plants and refineries.
F22Chromium-Molybdenum (2.25% Cr, 1% Mo)High-temperature service, superheaters, reheater tubes, steam turbines.Excellent high-temperature strength and resistance to creep, oxidation, and corrosion. Common in fossil-fuel plants and chemical refineries.
F91Chromium-Molybdenum-Vanadium (9% Cr, 1% Mo, 0.2% V)Superheater tubes, boilers, steam turbines in ultra-supercritical plants, power plant piping.Excellent resistance to high-temperature oxidation, corrosion, and creep. Used in high-stress, high-temperature applications.
F92Chromium-Molybdenum-Vanadium (9% Cr, 1% Mo, 0.2% V)Boilers, pressure vessels, and heat exchangers.Very high creep resistance and excellent weldability at elevated temperatures, widely used in fossil fuel and nuclear power plants.
