ASTM B619 UNS N10276 Hastelloy C276 Nickel Alloy Welded Pipe For Petrochemical Industry
ASTM B619 UNS N10276 Hastelloy C276 Nickel Alloy Welded Pipe For Petrochemical Industry
ASTM B619 UNS N10276 welded nickel alloy pipes are manufactured from UNS N10276, commonly known as Hastelloy C276. This specification covers welded, cold-worked, or solution-annealed pipes intended for general corrosion-resistant applications. Hastelloy C276 is a nickel-molybdenum-chromium superalloy with the addition of tungsten, renowned for its exceptional resistance to a wide range of aggressive chemicals, pitting, stress-corrosion cracking, and oxidizing atmospheres. It is widely used in chemical processing, petrochemical industry, oil & gas plant, pollution control, power generation, and marine applications owing to its immunity to stress corrosion cracking and pitting.
