Monel K500 (UNS N05500)
Cov alloy Monel K5{{1}0 yog tsim los ntawm npib tsib xee thiab tooj liab thiab muaj titanium alloy cov khoom ntawm 0.35 feem pua thiab 0.85 feem pua thiab 2.3 feem pua -3.15 feem pua ntawm txhuas. Ib qho me me ntawm Al thiab Ti cov ntsiab lus tuaj yeem ntxiv rau nag lossis daus Ni3 (Al, Ti) theem, uas ua rau lub zog siab thiab zoo corrosion kuj ntawm Monel 400 alloy ua tsaug rau nag lossis daus. Monel K500 muaj zog sib piv thiab hardness rau npib tsib xee-chromium alloys thiab nag lossis daus-hardening low-alloy steels nyob rau hauv chav tsev kub thiab pom zoo corrosion kuj nyob rau hauv hydrochloric acid, sulfuric acid, alkaline ib puag ncig, seawater, thiab lwm yam ib puag ncig. Nws kuj tseem tiv taus dej hiav txwv corrosion dua li tooj liab-based alloys. Tsis tshua muaj hlau nplaum permeability, tsis yog hlau nplaum hauv qab -101 degree, tsis tshua muaj plasticity txawm nyob rau ntawm -25 degree K, thiab lub peev xwm los tuav lub zog ntawm qhov kub siab tshaj 920 degree K yog txhua yam ntawm Monel K500.
Zoo corrosion kuj yog nthuav tawm los ntawm Monel K500 alloy nyob rau hauv ntau qhov chaw, nrog rau cov dej ntshiab, inorganic acids, ntsev, thiab alkalis. Chloride-ion kev nyuaj siab corrosion tawg yog tshwj xeeb resistant rau Monel K500. Thaum qhov kev ntxhov siab nyob ze heev rau lub zog tawm los, cov hlau alloy yog qhov yooj yim tshaj plaws rau kev ntxhov siab corrosion tawg hauv hydrofluoric acid vapor hauv lub xeev laus. Txawm li cas los xij, pitting corrosion yuav tshwm sim hauv cov dej hiav txwv uas ntsiag to lossis txav mus qeeb. Monel K500 muaj kev tiv thaiv zoo heev hauv cov dej hiav txwv ceev ceev thiab dej hiav txwv. Nyob rau hauv qaub roj, Monel K500 kuj qhia tau hais tias zoo corrosion kuj.
Hais txog kev ua haujlwm txias, Monel K500 alloy muaj qhov zoo ntawm qhov kub thiab txias, yog li yuav tsis muaj teeb meem. Txawm li cas los xij, thaum nws los txog rau kev ua haujlwm kub, lub alloy qhov kub thiab txias yog 871-1149 degree, thiab nws cov alloy tov annealing kub yog 793-971 degree, uas tuaj yeem ua rau kev ua tau zoo tag nrho. Cov khoom uas kub ua tiav yuav tsum tau muab tso rau hauv qhov kub ntawm 982 degree, hos cov khoom uas txias ua tiav yuav tsum tau muab tso rau hauv qhov kub ntawm 1038 degrees.
