ASTM A335 P9 Pipes are seamless alloy steel pipes manufactured in accordance with ASTM A335 / ASME SA335 standards and are designed for high-temperature and high-pressure service. These pipes are alloyed with chromium and molybdenum, which provide excellent resistance to oxidation, corrosion, and creep at elevated temperatures. ASTM A335 P9 Pipes are widely used in critical industrial applications where long-term strength and thermal stability are essential..
Metal Tubular Products is a worldwide stockist and supplier of ASTM A335 P9 Pipes, catering to industries such as power generation, oil & gas, petrochemicals, refineries, and fertilizer plants. The company maintains a ready stock of ASTM A335 P9 Pipes in a wide range of diameters, wall thicknesses, and lengths to support both urgent maintenance requirements and large-scale industrial projects across global markets.
ASTM A335 P9 Pipes supplied by Metal Tubular Products offer excellent mechanical properties and high resistance to deformation under extreme operating conditions. The chromium content improves oxidation and corrosion resistance, while molybdenum enhances creep strength and tensile performance. These characteristics make P9 pipes ideal for use in boilers, superheaters, reheaters, heat exchangers, and high-temperature piping systems..

ASTM A335 P9 Pipes are primarily used for high-temperature and high-pressure applications such as power plants, boilers, heat exchangers, refineries, petrochemical plants, and oil & gas processing facilities. Their chromium- molybdenum alloy composition provides excellent strength and oxidation resistance at elevated temperatures.
The designation “P9” refers to a chromium-molybdenum alloy steel grade containing approximately 8–10% chromium and 0.9–1.1% molybdenum, designed for high-temperature service with improved creep strength and corrosion resistance.
ASTM A335 P9 Pipes are supplied as per ASTM A335 / ASME SA335 specifications and are typically delivered in the normalized and tempered condition. All quality, testing, and inspection requirements are defined within the ASTM standard.
ASTM A335 P9 Pipes are manufactured and supplied in seamless (SMLS) form only, as required by the ASTM A335 specification for alloy steel pipes intended for high-temperature service.
