Hauj lwm lawm
Hlau alloy 725 (UNS N07725)yog nickel-chromium-molybdenum-niobium alloy uas tiv taus corrosion thiab muaj hnub nyoog hardenable rau lub zog siab heev. Nws muaj qhov tseem ceeb tib yam corrosion kuj zoo li INCONEL alloy 625, uas yog dav siv nyob rau hauv ib tug ntau yam ntawm corrosive ib puag ncig. Lub zog ntawm lub hnub nyoog-hardened INCONEL alloy 725 yog ntawm qhov kev txiav txim ntawm ob zaug ntawm annealed alloy 625. Vim hais tias lub zog ntawm alloy 725 yog tsim los ntawm kev kho cua sov, tsis yog los ntawm kev ua hauj lwm txias, ductility thiab toughness nyob twj ywm siab. Tsis tas li ntawd, lub zog tuaj yeem muab faib mus rau qhov loj lossis tsis sib xws uas tsis tuaj yeem ntxiv dag zog los ntawm kev ua haujlwm txias.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm INCONEL alloy 725 yog muab rau hauv Table 1. Cov qib siab ntawm nickel thiab chromium muab kev tiv thaiv corrosion hauv kev txo thiab oxidizing ib puag ncig. Cov ntsiab lus molybdenum tseem ceeb txhim khu kev tiv thaiv kom tsis txhob muaj kev tshaj tawm thiab muab kev tiv thaiv siab rau pitting thiab crevice corrosion. Tsis tas li ntawd, kev sib xyaw ua ke ntawm cov ntsiab lus ua rau cov hlau tiv taus hydrogen embrittlement thiab kev ntxhov siab-corrosion tawg.
Cov khoom ntawm INCONEL alloy 725 muaj txiaj ntsig zoo rau ntau yam kev siv uas yuav tsum tau muaj kev tiv thaiv corrosion zoo nrog rau lub zog siab. Lub alloy yog siv rau hangers, tsaws lub txiv mis, sab hnab tshos mandrels thiab polished bore receptacles nyob rau hauv qaub roj kev pab cuam, qhov twg nws resists cov teebmeem ntawm hydrogen sulfide, chlorides thiab carbon dioxide. Cov hlau kuj tseem zoo nkauj rau lub zog siab fasteners nyob rau hauv marine daim ntaub ntawv, qhov twg nws resists corrosion, pitting thiab crevice nres nyob rau hauv seawater.
