15-7PH ndi mpweya wa semi-austenitic woumitsa chitsulo chosapanga dzimbiri chokhala ndi mphamvu zambiri, kulimba kwambiri komanso kukana kwa dzimbiri.Kukana kwa dzimbiri pakutentha kwa TH 1050 ndi RH 950 ndikoyipa kwambiri kuposa zitsulo zosapanga dzimbiri zosapanga dzimbiri zamtundu wa 400 wa chromium-based 400, koma osati bwino ngati zitsulo zosapanga dzimbiri 304 za chromium-nickel.
PH15-7Mo (mtundu wa 632) muyeso wadziko lonse 0Cr15Ni7Mo2Al, Japan SUS632, ndi chitsulo chopangidwa posintha 2% ya chromium mu chitsulo cha 0Cr17Ni7Al ndi 2% molybdenum.Zofunikira zake ndizofanana ndi chitsulo cha 0Cr17Ni7Al, koma magwiridwe antchito onse ndiabwinoko.Mu boma austenite, akhoza kupirira zosiyanasiyana kuzizira kupanga ndi kuwotcherera njira, ndiyeno mphamvu apamwamba angapezeke pambuyo kutentha mankhwala;ili ndi mphamvu yabwino kwambiri yotentha kwambiri kuposa 550 ℃.Amagwiritsidwa ntchito popanga zida zomangira zozungulira, zotengera zosiyanasiyana, mipope, akasupe, nembanemba valavu, mitsinje ya sitima, ma disks a kompresa, mbali za riyakitala, zida zosiyanasiyana zamakina ndi zida zina zamapangidwe.
15-7PH Njira Yochizira Kutentha: A state, TH1050 State, RH950 State, CH900 State Three Heat Treatment Systems
State A: Pambuyo pa chithandizo chamankhwala pa 1050 ° C, kuziziritsa madzi kapena kuziziritsa mpweya.Mapangidwe a metallographic amadziwika ndi austenite.
TH1050 boma: Pambuyo pa chithandizo chamankhwala pa 1050 ° C, sungani pa 760 ° C ± 15 ° C kwa 90min, mpweya wozizira, wozizira mpaka 15 ° C kapena kutentha kwa chipinda mkati mwa 1h, sungani 30min, ndiye kutentha kwa 565 ° C ± 10. °C, sungani kwa 90min mumpweya, womwe umadziwikanso kuti 565 ° C kukalamba.Mapangidwe a metallographic amadziwika ndi mvula yowumitsa martensite.
RH950 boma: Pambuyo pa chithandizo chamankhwala pa 1050 ° C, sungani pa 955 ° C ± 15 ° C kwa mphindi 10, mpweya wozizira mpaka kutentha, ozizira mpaka -73 ° C ± 6 ° C mkati mwa maola 24, sungani maola 8, ndiye kutentha kwa 510 ° C ± 6 ° C, kusunga kwa mphindi 60 mu mpweya kuzirala, Amatchedwanso 510 ℃ ukalamba.Mapangidwe a metallographic amadziwika ndi mvula yowumitsa martensite.
CH900 state: Pambuyo pa chithandizo chamankhwala pa 1050 ° C, kuzizira kozizira ndi 60% mapindikidwe, kutentha kwa 490 ° C kwa 60min, kuziziritsa kwa mpweya mpaka kutentha.Mapangidwe a metallographic amadziwika ndi mvula yowumitsa martensite.
