Stainless Steel 347H Welding Neck Flanges are meticulously engineered to ensure superior performance and
reliability in high-temperature and high-pressure environments. As an austenitic stainless steel, 347H
features a higher carbon content, enhancing its creep resistance and making it ideal for applications that
involve prolonged exposure to elevated temperatures.
These welding neck flanges are designed to offer exceptional resistance to oxidation and corrosion,
maintaining their structural integrity even at temperatures up to 1500°F (816°C). This makes them
particularly suitable for high-temperature chemical processing, power generation, and industrial furnaces.
The long tapered hub of the welding neck flange ensures a smooth transition from the flange to the pipe,
reducing stress concentrations and providing a robust and leak-proof connection.
A standout feature of Stainless Steel 347H is its stabilization with niobium, which prevents chromium
carbide precipitation at grain boundaries. This crucial stabilization ensures that the material retains
its corrosion resistance in as-welded conditions, preventing weld decay and significantly enhancing the
lifespan of the flanges. This property is particularly beneficial for applications involving frequent
welding, ensuring long-lasting reliability and structural integrity.
