ASTM A182 F9 Alloy Steel Pipe Fittings Manufacturer, Supplier & Exporter in India, USA, Turkey & Nigeria – Mcneil Instruments
Mcneil Instruments manufactures and supplies ASTM A182 F9 Alloy Steel Pipe Fittings for pressure piping, refinery, petrochemical, power generation and other elevated-temperature applications.
ASTM A182 F9 is a 9Cr-1Mo chromium-molybdenum alloy steel forging grade, identified by UNS K90941 and Werkstoff 1.7386. Its higher chromium and molybdenum content compared with lower-alloy Cr-Mo grades provides a combination of elevated-temperature strength, oxidation resistance and resistance to certain high-temperature process environments.
F9 fittings are available in forged configurations such as socket-weld and threaded fittings, with dimensions, pressure classes, tolerances and other requirements specified by the applicable product standard. For forged socket-weld and threaded fittings, ASME B16.11 is the relevant dimensional and rating standard.
What Are ASTM A182 F9 Alloy Steel Pipe Fittings?
ASTM A182 F9 Alloy Steel Pipe Fittings are forged piping components manufactured from a chromium-molybdenum alloy steel containing approximately 8–10% chromium and 0.90–1.10% molybdenum.
The relatively high chromium content improves resistance to oxidation and scaling at elevated temperatures, while molybdenum contributes to high-temperature strength.
ASTM A182 defines the material requirements for forged alloy-steel piping components. The fitting’s configuration, dimensions, pressure class and connection details are governed by the applicable dimensional standard and purchase specification.
