Hastelloy C276 Round Bar is a nickel-molybdenum-chromium superalloy known for its outstanding corrosion resistance in aggressive chemical environments. The alloy is designated as UNS N10276 and is one of the most widely used corrosion-resistant materials in chemical processing industries. It provides excellent resistance against oxidizing chemicals, reducing agents, chlorides, wet chlorine gas, sulfuric acid, hydrochloric acid and seawater environments.
The unique chemical composition of Hastelloy C276 includes significant amounts of molybdenum and chromium, which provide superior resistance to localized corrosion such as pitting and crevice attack. Unlike conventional stainless steels, Hastelloy C276 maintains its integrity even in highly corrosive environments where exposure to acidic chemicals is continuous.
Hastelloy C276 Round Bars are extensively used in industries where safety, durability and long service life are critical requirements. Their excellent mechanical properties, weldability and corrosion resistance make them a preferred material for manufacturing pumps, valves, shafts, fasteners, reactors, pressure vessels and marine equipment.

The manufacturing of Hastelloy C276 Round Bars begins with the careful selection of premium quality raw materials. Nickel, molybdenum, chromium and other alloying elements are melted under controlled conditions to achieve precise chemical composition. Advanced refining techniques are employed to remove impurities and ensure metallurgical consistency.
After melting, the alloy is cast into billets and subjected to hot forging and hot rolling processes. These operations improve grain structure and mechanical properties while ensuring dimensional accuracy. The bars are then heat treated under controlled temperatures to optimize strength, ductility and corrosion resistance.
Depending on customer requirements, Hastelloy C276 Round Bars may undergo additional processes such as centerless grinding, polishing, machining and straightening. Each batch is subjected to chemical analysis, mechanical testing, ultrasonic inspection and dimensional verification before dispatch.
