Hastelloy C-22 Coil Description

The main elements of Hastelloy C22 coil 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,  the addition of 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. Besides,  it has good plasticity and toughness and can be used for cold and hot  processing. Hastelloy C22 coil also exhibits excellent oxidation  resistance and creep resistance at high temperatures. Hastelloy C22 coil  is widely used in aerospace, chemical industry, petroleum and other  fields because of its excellent corrosion resistance and high  temperature strength.
