When it comes to composition and mechanical properties, our Incoloy 800 Needle Valves are made from a nickel-iron-chromium alloy that contains about 30–35% nickel, 19–23% chromium, and the rest is iron, along with some aluminum and titanium. This unique blend provides the alloy with exceptional resistance to oxidation, carburization, and extended exposure to high temperatures. The material offers impressive tensile strength ranging from 520–690 MPa and maintains its integrity even in extreme thermal cycling conditions. At Paul Tube Fittings, we ensure that our valves are constructed with precision, featuring fine-threaded stems and durable seals for accurate flow control, making them a reliable choice for high-pressure and high-temperature fluid or gas systems.
