If you're looking for nickel-based alloy N6 stainless steel seamless pipe, Gnee offers a large inventory, factory-direct pricing, and fast global shipping. We supply nickel alloy N6 seamless pipe to over 60 countries with competitive wholesale pricing, certified quality, and fast global shipping.
Nickel-based alloy N6 seamless stainless steel pipe is a high-purity nickel tube (nickel content exceeds 99%). The "N6" designation indicates it is a pure nickel alloy. These seamless pipes offer enhanced strength and reliability, making them suitable for demanding industrial applications such as the chemical, petroleum, and petrochemical industries.
GNEE provides alloy N6 seamless stainless steel pipes, manufactured from a nickel-based superalloy composition (72.0-76.0% nickel, 14.0-17.0% chromium) with precise dimensional tolerances (outer diameter ±0.05mm, wall thickness ±0.03mm). The pipes are available in outer diameters of 6.0-114.3mm (1/4"-4.5") and wall thicknesses of 0.5-6.0mm (0.020"-0.236"), conforming to ASTM B163/B516 standards.
