ASTM A335 P92 Alloy Steel Pipes: Leading Choice for High-Temperature Applications
Kwality Steelage Pvt Ltd, based in Mumbai, India, is a trusted manufacturer and exporter of ASTM A335 P92 alloy steel pipes, recognized globally for their exceptional durability, corrosion resistance, and structural integrity in high-temperature applications. Known as Chrome Moly P92 pipes, these alloy pipes are engineered to withstand demanding environments in power plants, petrochemical facilities, and heavy engineering sectors. The composition of P92 pipes includes 8.50-9.50% chromium, 0.30-0.60% molybdenum, and balanced additions of vanadium, tungsten, and niobium. This precise alloy blend enhances their strength, creep resistance, and oxidation resistance, making them ideal for supercritical steam applications.
ASTM A335 P92 pipes are available in a seamless format, produced through both hot rolling and cold drawing processes for optimal dimensional accuracy and surface quality. These pipes exhibit a minimum tensile strength of 620 MPa, a yield strength of 440 MPa, and a maximum hardness of 250 HB, ensuring robustness and reliability under intense stress and elevated temperatures. The pipes meet the stringent standards of DIN 1.4901 and are designated under UNS K92460, equivalent to EN X10CrWMoVNb9-2. Available in a range of schedules from SCH 20 to SCH XXS, P92 pipes can be customized in sizes up to 36 inches in nominal bore.
Kwality Steelage utilizes advanced metallurgical processes to manufacture ASTM S/A 335 P92 pipes. The seamless pipes are normalized at 1040°C and tempered at a minimum of 730°C to achieve the desired microstructure, which provides superior creep resistance and enhances overall durability. The heat treatment processes are essential for ensuring that these pipes retain their mechanical integrity and hardness, particularly in high-pressure and high-temperature settings.
The robust properties of ASTM A335 P92 pipes make them highly sought-after in critical industries such as power generation, oil and gas, chemical processing, and shipbuilding. The versatility of Alloy Steel A/SA 335 GR. P92 Pipes & Tubes allows them to be used in heat exchangers, boilers, steam lines, and other components exposed to elevated temperatures and corrosive environments. Their enhanced thermal stability and resistance to wear are especially advantageous for applications that involve cyclic operations and high thermal fatigue.
Kwality Steelage offers a wide array of sizes, dimensions, and shapes for ASTM A335 P92 pipes, including round, square, rectangular, and hydraulic forms. Each pipe can be supplied with various end finishes like plain, beveled, or threaded to suit specific project requirements. Customers can request additional testing, such as NACE TM0177 or HIC testing, ensuring full compliance with project specifications. For inquiries, reach out to Kwality Steelage Pvt Ltd, your reliable Alloy Steel P92 Pipe exporter and Chrome Moly P92 pipe supplier, dedicated to providing the highest standards in alloy steel solutions.

To ensure the durability and stability of ASTM A335 P92 pipes in high-stress, high-temperature applications, pre-welding preparations and Post-Weld Heat Treatment (PWHT) are crucial. For pipes with thicknesses above 13 mm, PWHT is highly recommended to reduce the risk of stress cracking and maintain mechanical integrity. Preheating to 150°C is advisable for thin-walled sections, providing better results in environments with extreme temperature variations.
