Import Alloy Steel P9 Seamless Pipe — Buy in wholesale FOB from Supplier in India

Alloy Steel P9 Seamless Pipe from Stancore Steel International is manufactured to ASTM A335 standard with a nominal composition of 9 percent chromium and 1 percent molybdenum, a chrome-moly alloy engineered for sustained performance in high-temperature, high-pressure environments. The pipes carry a polished finish and are supplied in extra heavy (XH) schedule wall thickness, with source data indicating thicknesses ranging from 10 mm to 20 mm. This material grade is specifically developed for oil refineries, petrochemical plants, and power generation facilities where steam, hot oil, and corrosive fluid transport demand reliable metallurgical integrity.

The chromium content confers oxidation resistance at elevated temperatures, while molybdenum enhances creep strength and inhibits pitting corrosion, properties that distinguish P9 from lower alloy grades such as P11 or P5. In standard practice, ASTM A335 P9 seamless pipe is produced by hot rolling or cold drawing followed by full annealing or normalising and tempering to achieve the required mechanical properties. Typical hardness values for this grade fall in the range of 179-217 HB, and the material is commonly supplied in the normalised and tempered condition. Export-grade packaging in boxes is specified by the supplier to protect surface finish during international transit.

Buyers in the process piping, heat exchanger, and pressure vessel sectors source this grade when design temperatures exceed the limits of carbon steel and where resistance to sulphidic corrosion is required. Common procurement considerations include verifying that the supplied material meets ASTM A335 chemical and mechanical requirements, confirming NDE testing levels, and agreeing inspection protocols before shipment. The supplier's profile does not state specific stock dimensions or standard lead times, so buyers should confirm available sizes, mill test certificate provision, and any third-party inspection arrangements directly with Stancore Steel International.

Stancore Steel International maintains a registered address at 18/6 Vijay Apartment, 12th Khetwadi X Lane, Mumbai 400004, Maharashtra, India. The supplier holds a harbor-tier trust designation on the marketplace, though the response rate is recorded at 0.00 percent with an average response time of zero hours, indicating no response history is currently available through the platform. No additional company history, manufacturing capacity, employee count, or revenue figures are stated in the available profile data.

The listing presents Stancore Steel International as a source of ASTM A335 P9 seamless pipe with specific attention to polished finish and extra heavy schedule product, suggesting a focus on industrial grades for critical service applications. Buyers should independently verify the supplier's mill relationships, stockholding capabilities, and quality management system status before committing to orders. Direct communication with the Mumbai office is advised to establish response reliability and to negotiate inspection, certification, and delivery terms.
