Our Nickel Alloy 825 and Incoloy® 825 piping offer enhanced corrosion resistance for industries and applications that operate in extremely harsh environments. Featuring nickel-iron-chromium content, this alloy pipe also includes small amounts of molybdenum, copper, and titanium. Similar to most of the alloys in the Incoloy® family, Nickel Alloy 825 pipe is made from a unique chemical composition of 38-46% Ni, a minimum of 22% Fe, 19-23.5% Cr, 2.5-3.5% Mo, 1.5-3% Cu, maximum of 1% Mn, and 0.6-1.2% Ti. Nickel Alloy 825 is used in an array of industries and applications where superior corrosion resistance is vital to plant operations.

Alloy 825 Pipe is available in Seamless or Welded from Size ranges 1/8" up to 26". Listed below are common sizes. Please contact for sizes not listed.
