Shape

ASTM A182 Alloy Steel F11, F22, and F91 Flanges are high-quality flanges made from low-alloy steels, designed to withstand high-temperature and high-pressure environments. Each grade has distinct chemical compositions and properties suited for different applications.

ASTM A182 F11 Flanges are made from chromium-molybdenum steel, with a chemical composition that typically includes 1.00-1.50% chromium and 0.44-0.65% molybdenum. This combination provides excellent strength, creep resistance, and corrosion resistance in high-temperature environments up to 575°C (1070°F). F11 flanges are commonly used in power generation, petrochemical, and oil and gas industries for applications such as pipelines, valves, and pressure vessels.

ASTM A182 F22 Flanges are made from chromium-molybdenum-vanadium steel, with a chemical composition that generally includes 2.00-2.50% chromium, 0.87-1.13% molybdenum, and 0.25-0.50% vanadium. F22 flanges exhibit higher tensile strength and improved resistance to corrosion and oxidation at elevated temperatures up to 600°C (1110°F). They are often used in refineries, chemical plants, and power generation industries for applications like high-temperature boilers, fittings, and steam lines.

Alloy Steel A182 Flanges

ASTM A182 F91 Flanges, also known as Grade 90, are made from high-strength, high-toughness alloy steel with a unique chemical composition of 9.00-10.50% nickel and 0.90-1.10% chromium. F91 flanges offer exceptional corrosion resistance, particularly in sour gas environments with hydrogen sulfide (H2S). These flanges find applications in the oil and gas industry, especially in offshore and subsea environments, where resistance to sulfide stress cracking (SSC) is critical.

All three grades of ASTM A182 Alloy Steel Flanges undergo a heat treatment process to enhance their mechanical properties. They are typically normalized and tempered to improve their strength and toughness, ensuring their reliability in demanding conditions.
