Hastelloy C-22 Pipe Description

The main elements of Hastelloy C22 pipe include cobalt, chromium, tungsten, molybdenum and small amounts of aluminum, titanium and nitrogen. Cobalt element improves the strength and hardness of the alloy, chromium element has an important impact on the corrosion resistance of the alloy, tungsten and molybdenum can increase the high-temperature strength of the alloy. Moreover, the addition of aluminum and titanium elements can refine the grains and improve the toughness of the alloy, while the addition of nitrogen can improve the strength and corrosion resistance of the alloy. Besides, it has good plasticity and toughness and can work with both cold and hot processing. Hastelloy C22 pipe also features excellent oxidation resistance and creep resistance at high temperatures. Hastelloy C22 pipes are commonly used in aerospace, chemical industry, petroleum and other fields because of its excellent corrosion resistance and high temperature strength.
