The ASTM A335 Grade P91 alloy steel pipe is a ferritic alloy steel product with 9Cr-1Mo-V-Nb composition, designed for high-temperature service up to 625°C. It is a seamless pipe engineered for power generation, petrochemical and refinery applications where creep resistance and thermal stability are critical. The pipe is specified for boiler, superheater and steam line systems in thermal power plants and industrial energy operations.
Grade P91 is a modified version of 9Cr-1Mo steel, enhanced with vanadium and niobium to improve creep strength and resistance to high-temperature corrosion. Typical industry specifications for this grade include a tensile strength of 620 MPa minimum and a yield strength of 415 MPa minimum, with elongation of 20% as standard. The material is often supplied in normalized and tempered condition to meet stringent performance requirements.
Buyers of this pipe include EPC contractors, power plant developers and petrochemical facility operators sourcing material for critical high-temperature applications. Trade terms commonly requested include bulk quantities with fixed lengths, with packaging and logistics tailored to project timelines. Confirmation of delivery condition and dimensional tolerances is essential before finalizing orders.
