Essential details
Sufficient nickel content in Incoloy Alloy 925 provides protection against chloride-ion stress-corrosion cracking whilst in conjunction with the added molybdenum and copper resistance to reducing chemicals is enjoyed. Molybdenum additionally aids resistance to pitting and crevice corrosion whilst Chromium offers resistance to oxidizing environments. During heat treatment a strengthening reaction is caused by the addition of titanium and aluminium.
Applications:
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-hole and surface gaswell components including tubular products, valves, hangers, landing nipples, tool joints and packers. The alloy is also useful for fasteners, marine and pump shafting and high-strength piping systems.
