Incoloy hlau 925 (UNS N09925) nrog ntxiv ntawm molybdenum, tooj liab, titanium, thiab txhuas yog lub hnub nyoog hardenable nickel-hlau-chromium alloy, muab kev sib xyaw ua ke ntawm lub zog siab thiab zoo heev corrosion kuj. Cov ntsiab lus npib tsib xee txaus muab kev tiv thaiv chloride-ion kev nyuaj siab-corrosion cracking whilst nyob rau hauv conjuncton nrog ntxiv molybdenum thiab tooj liab, tiv thaiv kom txhob muaj tshuaj lom neeg. Molybdenum kuj tseem pab tiv thaiv pitting thiab crevice corrosion, thaum chromium muaj kev tiv thaiv rau oxidizing ib puag ncig. Thaum kho cov cua sov, cov tshuaj tiv thaiv muaj zog yog tshwm sim los ntawm kev sib ntxiv ntawm titanium thiab txhuas.

Cov ntawv thov uas xav tau kev sib xyaw ua ke ntawm lub zog siab thiab kev tiv thaiv corrosion kuj yuav xav txog Incoloy alloy 925. Resistance to sulfide stress cracking and stress-corrosion cracking in "qauv" crude oil and natural gas environments txhais tau hais tias nws yog siv rau down-qhov thiab nto gas-well Cheebtsam raws li zoo raws li nrhiav kev siv nyob rau hauv marine thiab twj tso kua mis shafts los yog high-lub zog piping systems.
