Max Tube Fittings stands out as a top manufacturer and supplier of Inconel 718 Ball Valves in Delhi, India, delivering top-notch solutions for high-pressure and corrosive service applications. Crafted from Inconel 718, a robust nickel-chromium alloy, these ball valves ensure leak-proof performance, outstanding durability, and dependable flow control, even in the harshest conditions. Perfectly suited for critical instrumentation and industrial systems, Inconel 718 Ball Valves find their place in aerospace, nuclear, petrochemical, chemical processing, oil & gas, and marine sectors, where precision, corrosion resistance, and high-temperature performance are vital for safety and efficiency.
Inconel 718 Ball Valves are primarily made up of nickel (50–55%), chromium (17–21%), iron, niobium (4.75–5.5%), molybdenum (2.8–3.3%), cobalt (≤1%), along with small amounts of titanium and aluminum. This unique blend gives them remarkable tensile strength of up to 1,270 MPa, yield strength around 1,050 MPa, and excellent resistance to fatigue, creep, and stress corrosion. These valves maintain their mechanical stability, dimensional integrity, and sealing performance even under high pressure, extreme temperatures (up to 700°C), and corrosive environments, making them perfect for critical flow control in industrial, chemical, and aerospace applications.
