Jade Alloys is a trusted source for Hastelloy C276 pipes and tubes engineered for the most aggressive service environments. Every Hastelloy C276 pipe and tube we supply is produced from traceable, high-purity nickel-alloy stock and inspected against international specifications before it leaves our facility.
Hastelloy C276 (UNS N10276) is a nickel-molybdenum-chromium alloy prized for its versatility across oxidising and reducing conditions. Its high molybdenum and tungsten content delivers exceptional resistance to pitting, crevice corrosion and chloride-induced stress-corrosion cracking, which is why an alloy C276 pipe is the default choice for wet chlorine, sulfuric and hydrochloric acid, sour gas and flue-gas desulfurisation duty. We hold ready stock across common schedules and can fabricate non-standard sizes to order, so buyers get both fast delivery on routine requirements and a single point of contact for special dimensions.
Whether you need a single Hastelloy C276 seamless pipe for a heat-exchanger repair or a bulk export lot of welded tube for a new process plant, Jade Alloys supplies the correct grade, documentation and packaging on time and to specification.

What Is Hastelloy C276 (UNS N10276)?
Hastelloy C276 is one of the most widely used nickel-base corrosion-resistant alloys in the world. A typical composition balances roughly 57% nickel with 15–17% molybdenum, 14.5–16.5% chromium, 4–7% iron and 3–4.5% tungsten, while carbon and silicon are deliberately held very low (0.010% C max). This low-carbon “L-grade” chemistry minimises grain-boundary carbide precipitation during welding, so a Hastelloy C276 pipe retains its corrosion resistance even in the as-welded condition, a major practical advantage for fabricators.
The result is an alloy that resists a broader range of chemicals than almost any other single material: strong oxidisers, reducing acids, chloride solutions and mixed-acid streams. Combined with good ductility, high tensile strength and excellent weldability, these properties make Hastelloy C276 tube and pipe a long-life, low-maintenance solution for chemical processing, oil and gas, marine and pollution-control systems.
