iSteel India manufactures and supplies Alloy Steel ASTM A182 F5 Flanges from Mumbai for piping systems that combine high temperature with corrosive service conditions. F5 flanges connect pipe sections and equipment through a bolted, gasketed joint designed to seal reliably as the line heats and cools through repeated cycles. The grade is a 5% chromium, 0.5% molybdenum alloy steel, developed for elevated-temperature applications where standard low-alloy grades start to oxidize or lose strength. That chromium content forms a stable oxide scale on the metal surface, slowing further oxidation even under continuous exposure to hot process gases. F5 holds mechanical strength across a wider temperature band than F1 or F11, which is why it appears in the hottest sections of a plant.
We produce F5 flanges as weld neck, slip-on, blind, socket weld, threaded, and lap joint types, forged to ASTM A182 and ASME SA182 and dimensioned to ASME B16.5. Pressure classes run from 150# through 2500#, with raised face, ring type joint, and flat face options covering the gasket and bolting arrangements used across different plant standards. F5's chromium content resists oxidation and scaling at temperatures where plain carbon steel would degrade within months of continuous service, and its corrosion resistance extends service life in flue gas and sulphur-bearing environments. Mechanical strength stays consistent through repeated thermal cycling, which matters in equipment that heats and cools regularly rather than running at one constant temperature. Typical applications include furnace piping, heat exchanger connections, refinery process units, petrochemical plants, power plant steam systems, and boiler piping where hot, corrosive gases would shorten the life of a lower alloy flange. iSteel India supplies F5 flanges domestically and exports them to project sites and stockists overseas.
