Crafted from Inconel alloys, primarily nickel-chromium-based, Inconel BSP and NPT fittings boast outstanding resistance to oxidation and corrosion. The typical material composition includes at least 72% nickel, 14–17% chromium, and 6–10% iron, along with small amounts of manganese, silicon, and carbon. These fittings showcase high tensile strength, excellent fatigue resistance, and stability at elevated temperatures, often surpassing 1000°F (540°C). Their mechanical properties feature yield strength between 30–45 ksi, ultimate tensile strength of 75–100 ksi, and superior creep and stress-rupture resistance, making them perfect for demanding industrial settings.
