Max Tube Fittings is a reputable manufacturer and supplier of Incoloy 800 Tube Fittings based in Delhi, India. They provide top-notch solutions for creating reliable, leak-proof connections in critical piping systems. Crafted from Incoloy 800, a nickel-iron-chromium alloy, these tube fittings boast remarkable resistance to oxidation, carburization, and stress corrosion cracking, even at high temperatures. Built for durability and precision, they deliver excellent mechanical strength, stability, and corrosion resistance in tough environments. Incoloy 800 Tube Fittings find extensive use in chemical processing, power generation, oil & gas, heat treatment equipment, and marine industries, ensuring long-lasting performance in demanding applications.
Incoloy 800 Tube Fittings are made up of nickel (30–35%), chromium (19–23%), and iron (the balance), with carefully controlled amounts of carbon, aluminum, and titanium to boost strength. This alloy is known for its exceptional resistance to oxidation, carburization, and chloride stress corrosion cracking. On the mechanical side, these fittings offer a tensile strength of around 520 MPa and a yield strength of about 205 MPa, all while maintaining toughness across a broad temperature range. Their impressive creep and rupture strength at elevated temperatures guarantee reliable, leak-proof connections, making them ideal for aggressive and high-temperature service conditions across various industrial sectors.
