Alloy 52 muaj 52% Nickel thiab 48% hlau thiab yog siv dav hauv kev lag luam.Nws nrhiav tau ib daim ntawv thov hluav taws xob, tshwj xeeb tshaj yog rau cov iav ntim khoom siv hluav taws xob, tshwj xeeb tshaj yog rau cov iav ntsaws ruaj ruaj.
Alloy 52 yog ib qho ntawm lub khob rau hlau sealing alloys tsim los siv nrog ntau lub tsom iav muag. Lub npe paub rau ib coefficient ntawm thermal expansion uas yuav luag tas li mus txog 1050f (565 c).

Txoj kev sib sau: |
Lub alloy muaj kev du me me thiab tuaj yeem tsim los ntawm tus qauv txhais tau tias. |
Vuam: |
Vuam los ntawm cov txheej txheem pa hluav taws xob yog qhov tsim nyog rau cov alloy. |
Kev Kho Cua Sov: |
Alloy 52 yuav tsum tau qhia tawm ntawm 1500f ua raws li los ntawm huab cua txias. Qib Nruab Nrab Kev Sib Raug Zoo Yuav Ua Tau Thaum 1000f. |
Forging: |
Forging yuav tsum tau ua nyob rau ntawm ib tug kub ntawm 2150 F. |
Cov Haujlwm Txias: |
Lub alloy yog yooj yim txias ua haujlwm. Kev kos duab kom sib sib zog yuav tsum tau sau tseg rau qhov kev ua haujlwm thiab qib kawm rau kev tsim dav dav. |
