Max Tube Fittings is a reliable manufacturer and supplier of Hastelloy Hydraulic Fittings based in Delhi, India. They specialize in providing high-performance solutions tailored for demanding fluid handling systems. Crafted from Hastelloy, a superalloy made of nickel, molybdenum, and chromium, these fittings boast exceptional resistance to pitting, stress corrosion cracking, and harsh environments, whether oxidizing or reducing. Engineered for leak-proof and dependable connections, Hastelloy Hydraulic Fittings deliver outstanding durability and performance even under high-pressure conditions. With their superior mechanical strength and corrosion resistance, they find extensive use in industries like chemical processing, marine, offshore, petrochemical, and power generation, where traditional materials often fall short against aggressive chemicals and tough operating conditions.
Hastelloy Hydraulic Fittings are mainly made up of nickel, with notable amounts of molybdenum and chromium, along with small quantities of elements like tungsten, cobalt, and iron. This unique composition grants them impressive resistance to hydrochloric acid, sulfuric acid, and other corrosive substances. On the mechanical side, these fittings offer a tensile strength of around 690 MPa and a yield strength of about 310 MPa, showcasing excellent toughness and fatigue resistance. They remain stable even under extreme temperatures and pressures, ensuring a long service life. Their capability to function effectively in both oxidizing and reducing environments makes them a trusted choice for highly corrosive hydraulic applications.
