Hastelloy C276 round bar is a high-performance alloy rod made from a nickel-molybdenum-chromium blend with added iron and tungsten. Known for its outstanding resistance to strong oxidizers, chlorides, and reducing agents, it performs well in extreme environments. The bar derives its strength and durability from its unique composition, which includes elements such as nickel, molybdenum, chromium, iron, cobalt, and tungsten. It has exceptional mechanical qualities, including a high tensile strength of 1,15,000 psi and yield strength of 52,000 psi, as well as excellent elongation at 40%. Preston Pipes & Alloys is a trusted name in supplying top-quality Hastelloy C276 round bars to industries worldwide. We focus on consistent quality and on-time delivery backed by detailed material traceability and certifications.
The Hastelloy C276 bar is known for its exceptional corrosion resistance, particularly in acidic or high-temperature environments. It's a popular choice in chemical processing, power generation, marine, and pollution control sectors. Due to its resistance to pitting and stress corrosion cracking, it is frequently employed in reactors, heat exchangers and pressure vessels. The hastelloy C276 rod also works well in pulp and paper operations, where harsh bleaching agents are involved. Engineers and fabricators choose it for its long-lasting performance in challenging conditions without frequent replacements or failures.
These bars are available in sizes ranging from 3 mm to 600 mm and come in finishes such as bright, pickled, mirror, and hairline. The material's melting point is 1370 °C, making it suitable for high-temperature applications. To meet exact dimensional tolerances, production methods such as hot rolling, cold drawing and centerless grinding are used. Each hastelloy C276 flat bar or hex bar can be supplied with Mill Test Certificates as per EN 10204 3.1 or 3.2 standards. The versatility in shapes, square bar, hex bar, or round, gives users flexibility based on their application needs.
We follow strict quality control processes for every hastelloy C276 round bar. They are manufactured as per ASTM B574, DIN 17752, ISO 9723, ISO 9724, and DIN 17754 standards. We conduct a variety of testing, including mechanical, ultrasonic, PMI, and visual inspections. To prevent damage during shipment, our team ensures that all Hastelloy C276 bars are placed in waterproof wrapping, wooden boxes, or pallets. Proper labeling helps to ensure speedy and traceable deliveries. Get reliable performance with high-quality hastelloy C276 bars designed for your applications.
