Hastelloy C276 Pipes offered by Nascent Pipe & Tubes are among the most trusted and high-performance nickel alloy pipes in the global industrial market. These pipes are manufactured using a corrosion-resistant nickel-molybdenum-chromium alloy with added tungsten for enhanced stability in aggressive chemical environments. With superior mechanical properties and outstanding resistance to a wide range of chemical media, Hastelloy C276 Pipes serve as the go-to solution for demanding industrial applications across chemical processing, pulp and paper, pollution control, waste treatment, and offshore industries.

One of the key highlights of Hastelloy C276 Pipes is their exceptional resistance to localized corrosion, including pitting and stress corrosion cracking. This makes them ideal for use in environments containing strong oxidizers, such as ferric and cupric chlorides, hot contaminated mineral acids, chlorine gas, formic and acetic acids, acetic anhydride, seawater, and brine solutions. The chemical composition of these pipes—rich in molybdenum (15–17%) and chromium (14.5–16.5%)—ensures excellent resilience against harsh conditions that would typically degrade lesser materials.
