Max Tube Fittings stands out as a reliable manufacturer and supplier of Inconel 718 Needle Valves based in Delhi, India. We specialize in delivering high-precision solutions tailored for critical flow control applications. Our valves, made from Inconel 718—a nickel-chromium alloy known for its remarkable mechanical strength and resistance to corrosion—ensure leak-proof, dependable, and precise flow regulation, even in the most extreme pressures and temperatures. Perfectly designed for instrumentation and high-pressure systems, these valves find their place in industries like aerospace, oil & gas, chemical processing, petrochemical, nuclear, and marine, where durability, precision, and resilience against harsh environments are crucial for safe and efficient operations.
Inconel 718 Needle Valves are primarily made up of nickel (50–55%), chromium (17–21%), iron, niobium (4.75–5.5%), molybdenum (2.8–3.3%), and cobalt (≤1%), along with small amounts of titanium and aluminum for age-hardening. This unique blend gives them exceptional tensile strength (up to 1,270 MPa), yield strength (around 1,050 MPa), and impressive resistance to fatigue, creep, and stress corrosion. These valves maintain their mechanical stability and sealing integrity even under extreme temperatures (up to 700°C) and high-pressure conditions, making them perfect for critical industrial and aerospace applications.
