15-7PH Khoom Khoom
15-7PH yog semi-austenitic nag lossis daus hardening stainless hlau nrog lub zog siab, siab hardness thiab zoo corrosion kuj.Tag nrho cov corrosion kuj nyob rau hauv tshav kub kho TH 1050 thiab RH 950 tej yam kev mob yog phem tshaj li cov qauv hardenable stainless hlau ntawm chromium-based 400 series, tab sis tsis zoo li cov chromium-nickel-based 304 stainless hlau.
PH15-7Mo (hom 632) lub teb chaws tus qauv 0Cr15Ni7Mo2Al, Nyiv SUS632, yog cov hlau tsim los ntawm kev hloov 2% ntawm chromium hauv 0Cr17Ni7Al steel nrog 2% molybdenum.Nws cov khoom tseem ceeb zoo ib yam li 0Cr17Ni7Al steel, tab sis tag nrho cov kev ua tau zoo dua li nws.Nyob rau hauv lub xeev austenite, nws tuaj yeem tiv taus ntau yam txheej txheem txias thiab vuam, thiab tom qab ntawd lub zog siab tshaj plaws tuaj yeem tau txais tom qab kev kho cua sov;nws muaj qhov kub thiab txias zog hauv qab 550 ℃.Nws yog siv nyob rau hauv kev tsim cov aviation nyias-walled structural qhov chaw, ntau lub thawv, kav, springs, valve membranes, nkoj shafts, compressor discs, reactor qhov chaw, thiab ntau yam khoom siv tshuaj thiab lwm yam structural qhov chaw.
15-7PH Kev kho cua sov: Ib lub xeev, TH1050 Lub Xeev, RH950 Lub Xeev, CH900 Lub Xeev Peb Cov Kev Kho Mob Kub Kub
Lub xeev A: Tom qab kev daws teeb meem ntawm 1050 ° C, dej txias lossis cua txias.Cov qauv metallographic yog tus cwj pwm los ntawm austenite.
TH1050 lub xeev: Tom qab kev kho mob ntawm 1050 ° C, khaws cia ntawm 760 ° C ± 15 ° C rau 90min, cua-txias, txias rau 15 ° C lossis chav kub hauv 1h, khaws cia rau 30min, tom qab ntawd kub rau 565 ° C ± 10 °C, khaws cia rau 90min hauv huab cua, tseem hu ua 565 ° C laus.Cov qauv metallographic yog tus cwj pwm los ntawm nag lossis daus hardening martensite.
RH950 lub xeev: Tom qab kev kho mob ntawm 1050 ° C, khaws cia ntawm 955 ° C ± 15 ° C rau 10 feeb, cua txias rau chav sov, txias rau -73 ° C ± 6 ° C hauv 24 teev, khaws cia rau 8 teev, Tom qab ntawd kub rau 510 ° C ± 6 ° C, khaws cia rau 60 feeb hauv huab cua txias, Kuj hu ua 510 ℃ laus.Cov qauv metallographic yog tus cwj pwm los ntawm nag lossis daus hardening martensite.
CH900 xeev: Tom qab kev daws teeb meem ntawm 1050 ° C, txias dov nrog 60% deformation, cua sov rau 490 ° C rau 60min, cua txias rau chav tsev kub.Cov qauv metallographic yog tus cwj pwm los ntawm nag lossis daus hardening martensite.
