Home > Alloy 20 Check Valve
Max Tube Fittings stands out as a top manufacturer and supplier of Alloy 20 Check Valves in Delhi, India. We specialize in providing durable and reliable flow control solutions tailored for industries that face aggressive chemical environments. Our valves are designed to facilitate one-way fluid flow while effectively preventing backflow. Crafted from Alloy 20—a nickel-iron-chromium austenitic alloy renowned for its remarkable resistance to sulfuric acid and chloride-induced corrosion—these valves boast robust construction, a leak-proof design, and compliance with international quality standards. At Max Tube Fittings, we ensure that our Alloy 20 Check Valves deliver safety, efficiency, and a long service life across various industrial applications.
Alloy 20 Check Valves are crafted from a nickel-iron-chromium alloy that contains 20–35% nickel, 19–21% chromium, 3–4% copper, along with some molybdenum. This unique composition grants them outstanding resistance to sulfuric acid, chlorides, and stress corrosion cracking. With a tensile strength of approximately 620 MPa and a yield strength around 300 MPa, Alloy 20 is built to withstand demanding conditions. Additionally, the alloy showcases high ductility, toughness, and excellent weldability. These mechanical and chemical properties make Alloy 20 Check Valves a dependable choice for corrosive environments, ensuring consistent and long-lasting performance.
