INCOLOY® alloy 925 (UNS N09925)
The properties of INCONEL alloy 718
INCOLOY alloy 925 is used in various
applications requiring a combination of high strength
and corrosion resistance. Because of the alloy’s
resistance to sulfide stress cracking and stress-corrosion
cracking in “sour” (H2S containing) crude oil and
natural gas, it is used for down-holevalves,
hangers, landing nipples, tool joints and packers
