Grade P22 ASTM A335 Alloy Seamless Pipe

The chromium-molybdenum alloy composition of ASTM A335 P22 Seamless Pipe gives it superior high-temperature strength, creep resistance, and oxidation stability. This makes it an ideal choice for power plants and refineries, which deploy it extensively in critical high-pressure applications such as superheaters, steam headers, and piping systems operating up to 580°C.
