Uses of Hastelloy Alloy Tubes
Hastelloy C276 tubes are used in industries that face extreme chemical and environmental challenges. They are essential in pollution control systems, marine engineering and heat exchanger units due to their durability and dependability. They are referred to as Nickel Alloy C276 Bourdon Tubes in instrumentation, ASTM B619 N10276 Capillary Tubes in analytical equipment, and DIN 2.4819 Furnace Tubes in high-temperature applications. Alloy C276 Gas Tubes are used for chemical transfer, C276 Hastelloy Condenser Tubes for cooling systems, and Nicrofer® 5716 Hydraulic Tubing in critical hydraulic controls.

Hastelloy C276 vs C22 Tubes
Hastelloy C276 Tubes offer better resistance to a wide range of strong oxidizers and wet chlorine compared to Hastelloy C22 Tubes. Alloy C276 withstand chemical environments due to its tungsten content, making it more versatile. C22 has better formability and is preferred for applications with moderate corrosion demands, while C276 is the go-to for highly aggressive chemical exposures.
