ASTM A335 Grade P11 alloy steel pipe from Stancore Steel International is a chrome-molybdenum solution engineered for high-temperature and high-pressure service in power generation, petrochemical refining, and oil and gas applications. The P11 grade contains 1.00% to 1.50% chromium and 0.44% to 0.65% molybdenum, delivering superior creep resistance at temperatures up to 550°C. Sizes range from 1/2 inch to 24 inch NB, with lengths tailored to project requirements.
This pipe meets ASTM A335 and ASME SA335 standards and is commonly exported with mill test certificates, including EN 10204 3.1 documentation upon request. The alloy’s composition ensures durability in boiler superheaters and process pipelines, where thermal stress and corrosion resistance are critical. Stancore Steel International supplies these pipes globally, with options for custom surface treatments and protective packaging.
Industries such as energy, petrochemical, and manufacturing rely on P11 pipes for transporting gases and fluids safely under demanding conditions. The pipe’s seamless construction and alloy composition minimize maintenance costs while maximizing service life. Buyers should confirm specific mechanical properties, such as tensile strength and elongation, which are critical for high-pressure applications.
