Incoloy 825 plate specifications

Incoloy 825 (UNS N08825, W.Nr 2.4858): plate, sheet and strip ASTM B424 / ASME SB424, bar ASTM B425, seamless pipe and tube ASTM B423, welded pipe B705 and welded tube B704, fittings ASTM B366 (WPNICMC).

Stabilised by titanium: 825 contains titanium to tie up carbon, so it resists intergranular attack after welding. That is why it is trusted for welded liners and patch plates that cannot be heat treated on site.

Pipe, tube and flanges: sizes confirmed per enquiry, from Mumbai stock.

Equivalents: W.Nr 2.4858, NiCr21Mo. Forgings and flanges to ASTM B564 / ASME SB564.

Typical chemistry: Ni 38–46%, Cr 19.5–23.5%, Mo 2.5–3.5%, Cu 1.5–3.0%, Ti 0.6–1.2%, iron balance. Density about 8.14 g/cm³.

Minimum properties, ASTM B424 annealed plate: tensile 586 MPa, yield 241 MPa, elongation 30%.

Welding note: 825 plate is commonly welded with ERNiCrMo-3 filler, which over-matches the base metal in corrosion resistance at the weld, a sensible choice for acid-wetted patches.
