Hastelloy C-276 Round Bar

Hastelloy-C-276 round bars stand as a testament to advanced alloy engineering, meticulously designed to conquer the most aggressive corrosive environments. Composed of a nickel-molybdenum-chromium matrix (with key additions of tungsten and cobalt), this superalloy forms a robust passive layer that resists pitting, crevice corrosion, and stress corrosion cracking in media like hydrochloric acid, sulfuric acid, and chloride solutions. Newstar Hardware’s Hastelloy-C-276 round bars adhere to ASTM B574 standards, delivering a minimum tensile strength of 730MPa and yield strength of 285MPa, with elongation exceeding 40% to balance durability and formability. The alloy’s unique microstructure ensures stability in both oxidizing and reducing conditions, making it indispensable for chemical reactors, flue gas desulfurization systems, and offshore oil equipment. Available in diameters from 12mm to 250mm, these bars feature precise dimensional control and a polished surface finish to minimize corrosion hotspots. Rigorous quality checks include intergranular corrosion testing (ASTM A262 Practice E) and ultrasonic inspection, guaranteeing reliability in pharmaceutical manufacturing, marine engineering, and waste treatment sectors. With excellent weldability and machinability, Hastelloy-C-276 round bars enable the fabrication of complex components while maintaining mechanical properties across extreme service conditions.
