Monel 400 thiab Monel 405 yog ob qho sib txuas nickel-tooj liab uas muaj cov khoom tiv taus xeb zoo sib xws. Txawm li cas los xij, kuj muaj qee qhov sib txawv ntawm lawv:
1. Cov khoom xyaw:
Monel 400 muaj li ntawm 67% nickel thiab 30% tooj liab, thiab muaj cov khoom me me xws li hlau, manganese thiab silicon. Ntawm qhov tod tes, Monel 405 muaj cov khoom sib xyaw me ntsis nrog rau qhov ntxiv me me (0.5-1.5%) ntawm txhuas. Qhov kev ntxiv no pab txhim kho cov khoom siv kho tshuab ntawm cov hlau thiab ua rau nws lub zog nce ntxiv. , thiab lwm yam.
2. Lub zog thiab qhov nyuaj:
Vim yog ntxiv cov txhuas, Monel 405 ua rau pom muaj zog thiab tawv dua li Monel 400. Qhov no ua rau Monel 405 tsim nyog rau cov ntawv thov uas xav tau lub zog tensile siab dua thiab tawv.
3. Kev vuam tau:
Piv nrog Monel 400, Monel 405 qhia tau tias muaj kev txhim kho weldability. Kev ntxiv txhuas pab txo qhov kev tsim ntawm intergranular carbides thaum lub sijhawm vuam, txhim kho qhov weldability ntawm cov hlau, thiab txo qhov kev pheej hmoo ntawm weld tawg.
4. Daim Ntawv Thov:
Vim nws txoj kev tiv thaiv xeb zoo heev, tshwj xeeb tshaj yog nyob rau hauv dej hiav txwv ib puag ncig, Monel 400 yog siv dav hauv ntau yam lag luam, suav nrog kev ua dej hiav txwv, kev ua tshuaj lom neeg, roj thiab roj av. Monel 405 muaj zog thiab weldability ntau dua thiab feem ntau siv rau hauv cov ntawv thov xws li cov twj tso kua mis, cov khoom siv fasteners thiab cov khoom siv valve.
5. Muab ib tus neeg tshwj xeeb rau koj:
Ua lub luag haujlwm rau kev teeb tsa thiab kev sib koom tes ntawm kev cob qhia tua hluav tawskom ntseeg tau tias qhov kev siv lub tshuab laum tau zoo.
Zuag qhia tag nrho, thaum Monel 400 thiab Monel 405 muaj kev tiv thaiv corrosion zoo heev, Monel 405 muaj zog thiab weldability ntau dua li Monel 400, ua rau nws yog qhov kev xaiv zoo dua rau qee qhov kev siv.
