Hastelloy C22 Pipes

What is Hastelloy C22 Pipes ?

Hastelloy C22 pipe, also called Alloy C22 or UNS N06022 pipe, is made from a nickel-chromium-molybdenum-tungsten alloy. It offers strong resistance to corrosion in both oxidizing and reducing environments. This makes it useful in harsh industrial settings. Parag Metals is a trusted source for quality alloy C22 seamless pipe, known for reliable supply and fair pricing. The material has a density of 8.69 g/cm³, melts at 1399°C, and has high tensile strength (690 MPa) with good elongation (45%), giving it both toughness and flexibility.

These pipes are strong, easy to weld, and stand up well to high heat and pressure, which makes them a solid ideal choice for various industrial uses. We offer pipes in seamless, welded, ERW, and fabricated types that meet ASTM B622, ASTM B619, and ASME SB626 standards. Sizes range from 15″NB to 150″NB with an outer diameter span of 30mm to 150mm, and wall thickness ranges from 2.5mm to 25mm. You can choose from schedules like SCH10 to XXS and it comes in single, double random, or cut lengths.
