ASTM A335 P22 Alloy Steel Pipe & Tube — Frequently Asked Questions
ASTM A335 (ASME SA335) is the standard specification for Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service. Grade P22 (UNS K21590), also known as 2 ¼ Cr – 1 Mo, is a medium-alloy steel widely used for its excellent combination of tensile strength, resistance to softening, and oxidation resistance at elevated temperatures (up to ~593°C / 1100°F). Dipti Metal is a Top ASTM A335 P22 Alloy Steel Pipe & Tube Manufacturer and Importer.
P22 alloy steel is the industry standard for conventional high-temperature/high-pressure steam service where creep resistance is necessary but the extreme performance of P91 is not required. Key applications include boiler tubes, superheater and reheater elements, hot steam piping, and high-pressure oil and gas process lines in refineries. Dipti Metal ensures full compliance with the P22 specifications for these critical applications.
The most common and exact European equivalent for ASTM A335 P22 (UNS K21590) is the DIN/EN material number 1.7380 (or 10CrMo9-10). This grade is globally recognized and often dual-certified for the same demanding high-temperature applications. Dipti Metal is a Worldwide recognized A335 P22 Alloy Steel Pipe & Tube Manufacturer and Stockist, guaranteeing cross-standard traceability with MTCs.
Yes, Post-Weld Heat Treatment (PWHT) is generally mandatory for A335 P22 pipes after welding. This is done to achieve the specified mechanical properties, relieve residual stress, and restore the microstructure damaged by the heat of welding. The typical PWHT temperature range for P22 is 690°C to 770°C. Dipti Metal supplies pipes that have undergone the correct normalizing and tempering heat treatment and provides guidance on critical welding procedures.
P22 (2.25Cr-1Mo) is a classic medium-alloy steel, whereas P91 (9Cr-1Mo-V-Nb) is a 'Modified' advanced ferritic steel. P91 is micro-alloyed with Vanadium and Niobium to provide far superior creep strength at temperatures up to 600°C, allowing for thinner walls and lighter weight. P22 is typically used for slightly lower-temperature or less critical applications than P91, offering excellent performance at a lower material cost and less complex welding requirements. Dipti Metal supplies both P22 and P91 to meet varying project demands.
