ASTM B163 UNS N08825 / DIN 2.4858 / Incoloy 825 Seamless Nickel Alloy Heat Exchanger Tube

ASTM B163 Incoloy 825 seamless tube represents a high-performance, corrosion-resistant product designed and manufactured to exacting standards for critical service in heat exchangers, condensers, and demanding process environments where reliability under pressure and corrosion is paramount. Its seamless construction and the proven properties of Incoloy 825 make it a cornerstone material for challenging industrial applications.

Sizes: Typically covers a wide range of OD and wall thickness combinations common for heat exchanger tubing (e.g., OD from ~1/4" to 3"+, WT as per schedule or BWG).

Temper: Usually supplied in the solution annealed condition (as required by ASTM B163 for corrosion resistance).
