Hastelloy C22 round bar is a strong nickel-chromium-molybdenum alloy known for its high corrosion resistance. Its chemical composition includes about 56% nickel, 22% chromium, and 13% molybdenum, with added iron, tungsten and cobalt. Parag Metal supplies Hastelloy C22 bars with solid mechanical strength and stable physical properties that meet demanding industrial standards, making it ideal for tough environments. Also known as Hastelloy UNS N06022 Round Bars, this alloy keeps its strength and shape across a wide range of temperatures.
This alloy offers excellent resistance to rust, acids and pitting, especially in chemical-heavy or halide-rich areas. These round bar is used in chemical plants, pollution control systems, paper processing, and flue gas cleaning. Its high molybdenum, chromium, and tungsten content allows it to stand up to aggressive chemicals like chlorine, hot acids and seawater. C22 alloy bar is a top choice when you need strength, safety, and long-lasting use.
