Hastelloy C276 Welded Pipe
Steel Pipe & Tubes has been a leading supplier of Inconel alloy piping solutions.
Hastelloy C276 Welded Pipe
Hastelloy C276 Welded Pipe is a tubular product manufactured by forming and welding high-quality plate or strip, designed for robust performance in a vast range of severe corrosive environments. Made from the nickel-molybdenum-chromium superalloy UNS N10276, this pipe is one of the most versatile corrosion-resistant alloys available. Manufactured to the ASTM B619 standard, modern welding techniques ensure the weld seam possesses mechanical and corrosion-resistant properties equivalent to the base metal, offering a reliable and cost-effective solution for large-diameter or standard piping systems.
The alloy’s high Molybdenum content provides exceptional resistance to localized corrosion such as pitting and crevice corrosion. The low carbon content minimizes carbide precipitation during welding, maintaining corrosion resistance in the as-welded condition. This makes Hastelloy C276 Welded Pipe the workhorse alloy for chemical processing, pollution control, pulp and paper, and industrial waste treatment industries, where it reliably handles aggressive media like sulfuric acid, hydrochloric acid, and sour gas.

Frequently Asked Questions (FAQs)
The main manufacturing standard for Hastelloy C276 welded pipe is ASTM B619 (Specification for Welded Nickel and Nickel-Cobalt Alloy Pipe).
No. With modern welding technologies and quality control, the weld seam is metallurgically sound and provides corrosion resistance and mechanical strength equivalent to the base metal. All pipes undergo testing to ensure weld integrity.
Welded pipe is often a more economical choice, especially for diameters above 2 inches. It is suitable for most industrial applications. Seamless is typically specified for extremely high-pressure systems or when zero risk of weld-related issues is permissible.
Yes, one of the key benefits of C276 is its low carbon content, which minimizes carbide precipitation during welding. This allows it to be used in the as-welded condition without loss of corrosion resistance.
ERW (Electric Resistance Welding) and EFW (Electric Fusion Welding) are two different methods for creating the longitudinal seam. The choice depends on the pipe's diameter, wall thickness, and specific application requirements, but both produce a high-integrity pipe under ASTM B619.
