As a trusted Hastelloy C276 Bar manufacturer in India, Sagar Prakash Alloys focuses on high-performance Hastelloy C276 round bars strictly following ASTM B574/ASME SB 574 specifications. This alloy has outstanding performance in highly aggressive chemical environments; Hastelloy C276 (UNS N10276) is the best nickel-molybdenum-chromium alloy designed for extreme conditions, particularly in the chemical processing, oil and gas, and waste treatment industries.
Unmatched Composition and Technical Specifications
Hastelloy C276, also known under the designation UNS N10276, has a composition of 14.5–16.5% chromium and 15.0–17.0% molybdenum, and the carbon content is limited to a maximum of 0.010%. Such a low-carbon grade inhibits the precipitation of carbides during welding and thus offers excellent resistance to intergranular corrosion. The high concentration of molybdenum in the alloy provides enhanced protection against localized corrosion, possibly pitting and crevice corrosion in environments rich in chlorides. With 4.0–7.0% iron and 4.0–4.5% tungsten, this alloy resists oxidizing acids like nitric, sulfuric, and hydrochloric acids while maintaining structural integrity.
Mechanical Strength and Durability
Hastelloy C276 round rods have a minimum tensile strength of 100,000 psi (690 MPa) and offset yield strength of 41,000 psi (283 MPa) at 0.2%. Even after long exposure to high-temperature environments up to 1900°F (1038°C), elongation of 40% in 2 inches indicates remarkable ductility. This unique combination of strength and flexibility makes C276 bar highly suitable for the construction of reactors, heat exchangers, and flue gas desulfurization systems where thermal stability coupled with mechanical reliability is critical.
Precision Manufacturing and Compliance
Our ASTM B574 UNS N10276 bars are made using hot or cold finishing techniques that are then controlled and followed by solution annealing for a uniform microstructure. The dimensional tolerances are stringent according to ASTM B574. For diameters between 7.94 and 19.05 mm, the permissible variation is ±0.30 mm, whereas for larger bars, i.e., diameters between 19.05 and 88.9 mm, it is ±0.25 mm. Out-of-roundness is limited to 0.61 mm for smaller diameters; this ensures standardization in roundness, which helps in further machining or assembly processes. Each bar is tested chemically and mechanically by ASTM E1473 and ASTM E8 standards, respectively.
Advantages of Hastelloy C276
Nickel Alloy C276 round bar performs better in environments poisoned by chlorides, sulfides, and acidic media than conventional alloys. Hastelloy C276 is broadly utilized in offshore platforms and the pulp/paper industry due to its resistance to stress-corrosion cracking in acidic chloride solutions. Another great feature of this alloy is its suitability for working with mixed acids, particularly HNO3/HCl mixtures, where other materials fail miserably. While providing the strength required for high-pressure applications, it makes for lightweight construction due to its 8.87 g/cm³ density.
