F11 class 1, 2, 3 (~1.7338)

ASTM A182 Alloy Steel grade F11 is a chromium-molybdenum alloy steel widely utilized across critical industries, including oil and gas, petrochemical, chemical processing, and power generation. Its primary applications lie in high-pressure and high-temperature environments, making it essential for components within oil and gas pipelines, steam boilers, pressure vessels, heat exchangers, and other critical equipment requiring robust performance. It can be case-hardened, it can be welded and it is resistant to creep 550°C. It is used for the fabrication of tubes, boilers and superheaters or for the transportation of overheated steam with a high pressure. it is easily machinable, even at the raw state of rolling or normalised.

A key advantage of ASTM A182 Alloy Steel grade F11 is its combination of high strength and excellent corrosion resistance. The specific alloying elements, notably chromium and molybdenum, contribute to its high resistance to oxidation and sulfidation at elevated temperatures, ensuring long-term reliability in demanding conditions.
