Harsh Flanges stands out as a top-notch manufacturer and supplier of premium Alloy Steel Flanges right in the heart of Mumbai, India. They specialize in crafting flanges from a variety of alloy steels, including ASTM A182 F5, F9, F11, and F22. This makes them a go-to choice for industries that need components capable of handling high temperatures, intense pressures, and corrosive environments. These flanges play a crucial role in ensuring leak-proof connections for critical applications. Harsh Flanges boasts an extensive selection of alloy steel flanges, featuring slip-on, weld neck, blind, and threaded types, all produced to meet international standards.
Alloy Steel Flanges are made from carbon steel that’s enhanced with elements like chromium, molybdenum, manganese, and silicon to boost their mechanical properties. For example, ASTM A182 F5 typically contains about 0.05–0.15% carbon, 0.30–0.60% manganese, 4.00–6.00% chromium, and 0.44–0.65% molybdenum. This unique blend gives the flanges impressive tensile strength, usually around 485 MPa, a yield strength of 275 MPa, and an elongation of 20% over 2 inches. They also excel in resisting oxidation and corrosion at high temperatures, making them ideal for demanding industrial applications.
