Hastelloy C276 Pipes are produced according to international standards such as ASTM B619, ASTM B622 and ASTM B626 UNS N10276. These pipes are produced in seamless, welded and ERW varieties in sizes from 1/8″ NB to 12″ NB (custom sizes on request). The pipes are strong, have precise dimensions, and withstand corrosion, making them ideal for harsh environments.
Hastelloy C276 is commonly employed in industries that operate in corrosive environments, including chemical processing, marine engineering, oil and gas, power generation, pollution control and pharmaceutical manufacturing. With excellent resistance to oxidizing and reducing environments, pitting and crevice corrosion, it is used in heat exchangers, scrubbers, evaporators, pressure vessels, and more. Hastelloy C276 is a highly corrosion resistant alloy, even in the most extreme conditions, when compared to stainless steel, Inconel and Monel alloys.
What is Hastelloy C276 Pipe?
The Hastelloy C276 Pipe (or Hastelloy C276 Tube) is made from Hastelloy C276, a nickel-molybdenum-chromium alloy containing tungsten. The Hastelloy C276 Pipe and Tube is a high-quality material, providing a high resistance to oxidizing and reducing environments. ASTM standard B622 covers Hastelloy C276 seamless pipe whereas ASTM standard B619 covers the welded form of the pipe. This feature enables it to be used in a wide range of aggressive environments.
The Alloy C276 Pipe (UNS N10276 / DIN 2.4819) with a low carbon content prevents carbide precipitation and ensures high corrosion resistance in the as-welded condition. It has excellent resistance to pitting and crevice corrosion and is widely used in chemical processing, pollution control, marine applications and heat exchanger equipment. The Hastelloy C276 tube has good resistance to reducing and oxidising environments and can be supplied in round, square or rectangular shapes in bright annealed, seamless and welded forms.

Frequently Asked Questions: Hastelloy C276 Pipe (ASTM B622 / UNS N10276)
What is the difference between ASTM B622 and ASTM B619 for Hastelloy C276 pipe?
ASTM B622 covers seamless pipes and tubes of nickel and nickel alloys including Hastelloy C276 (UNS N10276). ASTM B619 covers welded pipes of the same alloy family. Both standards are commonly specified for the same applications; the choice depends on whether seamless or welded construction is required. Seamless pipes under ASTM B622 are generally preferred for high-pressure and high-temperature services, while welded pipes under ASTM B619 are widely used where cost efficiency is a priority. Kalpataru Piping supplies both ASTM B622 seamless and ASTM B619 welded Hastelloy C276 pipes with full mill test certificates.
How does Hastelloy C276 pipe compare to SS 316L pipe in corrosive environments?
Hastelloy C276 (UNS N10276) significantly outperforms SS 316L in highly corrosive environments. C276 contains approximately 16% molybdenum and 15% chromium, giving it exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich, acidic, and reducing media where 316L would fail. C276 also resists wet chlorine, hypochlorite, and chlorine dioxide, making it the preferred choice for chemical processing, flue gas desulfurization, and marine applications. While 316L is suitable for mild corrosion environments, C276 pipe is the industry standard wherever aggressive chemical exposure is expected.
What is the price per kg of Hastelloy C276 seamless pipe in India?
The price of Hastelloy C276 seamless pipe per kg in India varies based on size, schedule, quantity, and current nickel and molybdenum market prices. As a specialty nickel alloy, C276 pipe is priced considerably higher than stainless steel. For an accurate and competitive price per kg based on your specific size and schedule requirements, please contact Kalpataru Piping directly with your inquiry. We offer competitive pricing with full ASTM B622 certification and mill test reports.
What schedules are available for Hastelloy C276 seamless pipe?
Hastelloy C276 seamless pipe is available in a wide range of wall thicknesses including Schedule 5S, 10S, 40, 80, 160, and XXS. The pipe schedule weight chart on this page lists the approximate weight per metre for common nominal bore sizes from 1/2 inch to 12 inch. Custom wall thicknesses can also be manufactured to project specifications. Kalpataru Piping maintains ready stock of the most common schedules for quick delivery.
In which industries is Hastelloy C276 pipe most commonly used?
Hastelloy C276 pipe (UNS N10276, ASTM B622) is widely used in chemical processing, pharmaceutical manufacturing, oil and gas production and refining, flue gas desulfurization, pollution control, marine engineering, pulp and paper production, and heat exchanger systems. Its exceptional resistance to oxidizing and reducing acids, chlorides, and wet process phosphoric acid makes it the alloy of choice wherever standard stainless steels, Inconel, and Monel alloys are insufficient. It is also approved and used in ARAMCO, PED-regulated, and offshore applications.
