Understanding ASTM A335 P22: The Chrome-Moly Edge

ASTM A335 P22 is a seamless ferritic alloy-steel pipe suitable for high-temperature service. The alloy’s composition typically includes:

  • Chromium (1.90–2.60%): Enhances strength, resistance to oxidation, and corrosion resistance.
  • Molybdenum (0.87–1.13%): Boosts tensile strength, wear resistance, and creep strength under prolonged high-temperature conditions.

These properties make P22 Chrome Moly pipes suitable for high-pressure environments where safety and performance cannot be compromised.
