Hastelloy C-22 Bar Description

The main elements of Hastelloy C22 bar include cobalt, chromium, tungsten, molybdenum and small amounts of aluminum, titanium and nitrogen. Among them, cobalt element can improve the strength and hardness of the alloy, chromium element has an important impact on the corrosion resistance of the alloy, tungsten and molybdenum can improve the high-temperature strength of the alloy. In addition, aluminum and titanium elements can help 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. What is more, it has good plasticity and toughness and can be used for cold and hot processing. Hastelloy C22 bar also exhibits excellent oxidation resistance and creep resistance at high temperatures, making it a popular choice in aerospace, chemical industry, petroleum fields.
