Incoloy 825 Seamless Pipe (UNS N08825)
ASTM B423 Incoloy 825 pipe with copper addition for sulfuric acid resistance. Chemical processing, pickling, pollution control.
Material
Incoloy 825 (UNS N08825)
OD Range
3 – 168mm (1/8" – 6")
WT Range
0.5 – 25mm
Standard
ASTM B423 / B704 / B705
Overview
Incoloy 825 differs from Inconel 625 with its higher iron content and strategic copper addition (1.5-3%), providing outstanding resistance to sulfuric and phosphoric acids. This makes it the material of choice for chemical processing plants handling mixed acids, pickling operations, and pollution control scrubbers. Excellent chloride SCC resistance.
