Alloy 330 weld neck flanges are specifically designed for high temperature furnace applications such as vacuum furnaces, heat treating and brazing applications. The most prized trait of alloy 330 is its ability perform under cyclic conditions of temperature extremes from heating and cooling; as well as in alternate carburizing and oxidizing atmospheres. An austenitic nickel-chromium-iron-silicon alloy, 330 weld neck flanges also offer industry a low coefficient of expansion, excellent ductility, and high strength.
