Forged fittings of Incoloy 825 are manufactured using a nickel-iron-chromium alloy with the addition of molybdenum, copper, and titanium, which exhibit superior resistance to a wide variety of corrosive environments. These fittings are particularly resistant to reducing and oxidizing acids, such as sulfuric and phosphoric acid. Mechanically, they are very strong, have good impact strength, and excellent stability at high temperatures. Incoloy 825 is resistant to stress-corrosion cracking, pitting, and crevice corrosion, and remains ductile when welded and heat treated. Their strong mechanical and chemical properties render them ideal for high-stress applications under corrosive and thermally severe conditions.
