The Inconel forged fittings produced by Devang Fittings are made using nickel-chromium-based superalloys, primarily Inconel 600, 625, and 825. These alloys typically consist of about 58–72% nickel, 14–23% chromium, along with elements like molybdenum, iron, and niobium, which provide exceptional resistance to corrosion and oxidation. Their mechanical properties boast tensile strength reaching up to 827 MPa, yield strength around 414 MPa, and remarkable resistance to creep and fatigue. These features make the fittings perfect for high-temperature and high-stress applications, such as in chemical plants, nuclear reactors, and offshore platforms, where traditional materials might not hold up.
