1. Brief introduction:

   It’s A Ni-Fe-Cr alloy with additions of Mo and Cu.

   It combines the high strength of a precipitation-hardenable alloy with the excellent corrosion resistance of alloy 825.

   It has outstanding resistance to general corrosion, pitting, crevice corrosion and stress-corrosion cracking in many aqueous environment, including those containing sulfides and chlorides.

   It is widely used for surface and down-hole hardware in sour gas wells and for oil-production equipment.
