Max Tube Fittings is a well-respected manufacturer and supplier of Hastelloy Tube Fittings based in Delhi, India. They specialize in providing precision-engineered solutions designed for highly corrosive and demanding environments. Made from Hastelloy, a nickel-molybdenum-chromium alloy, these tube fittings offer remarkable resistance to pitting, stress corrosion cracking, and both strong oxidizing and reducing agents. They guarantee leak-tight, secure connections in high-pressure and high-temperature applications. Thanks to their exceptional mechanical strength and durability, Hastelloy Tube Fittings are widely utilized in industries like chemical processing, marine, petrochemical, power generation, and environmental sectors, where traditional materials often fall short against aggressive media and extreme conditions.
Hastelloy Tube Fittings are primarily made up of nickel (about 58–70%), molybdenum (15–30%), and chromium (12–23%), along with small amounts of elements like cobalt, tungsten, and iron. This unique alloy composition gives them outstanding resistance to hydrochloric acid, sulfuric acid, and seawater. On the mechanical side, these fittings boast a tensile strength of around ~690 MPa and a yield strength close to ~310 MPa, along with excellent toughness, ductility, and fatigue resistance. They maintain their structural integrity in both cryogenic and high-temperature settings, ensuring a long service life. Their robust performance makes them perfect for handling aggressive industrial fluids.
