Yaman Steel stands out as a trusted manufacturer and supplier of Incoloy 800, 800H, and 800HT pipe fittings right in the heart of Mumbai, India. They specialize in providing high-temperature and corrosion-resistant alloy solutions that are crucial for various industrial applications. These alloys, which are based on nickel, iron, and chromium, are crafted to deliver exceptional strength and oxidation resistance even at elevated temperatures. Incoloy 800 is known for its solid general corrosion resistance, while the 800H and 800HT variants take it a step further with improved creep and rupture strength, thanks to their carefully controlled carbon content and grain size. These pipe fittings are designed to maintain their structural integrity and resist carburization, oxidation, and nitriding, even in the harshest operating conditions.
The Incoloy 800/800H/800HT pipe fittings from Yaman Steel boast a well-balanced chemical composition, featuring around 30–35% nickel and 19–23% chromium, along with iron and carefully managed additions of carbon and aluminum. The 800H and 800HT versions have higher carbon levels and undergo specific heat treatments to enhance their mechanical properties at high temperatures. Typically, their tensile strength ranges from 450 to 600 MPa, showcasing excellent yield strength and elongation. These characteristics ensure outstanding creep resistance, weldability, and long-lasting performance under continuous thermal and mechanical stress.
