CF8M cam khwb cia stainless hlau qhib impeller rau centrifugal twj los ntawm peev casting,CNC machiningthiab dynamic balancing.
CF8M yog cov cam khwb cia austenitic stainless hlau uas them los ntawm ASTM A351, ASTM A743 thiab ASTM A744 tus qauv. CF8M sib npaug rau SS 316 / F 316 thiab Suav Standard 0Cr17Ni12Mo2. CF8M yog molybdenum bearing hloov kho ntawm CF8 alloy thiab yog cov cam khwb cia sib npaug ntawm wrought AISI 316 Stainless hlau. Lub xub ntiag ntawm molybdenum tsub kom qhov dav dav corrosion tsis kam thiab tsis kam rau pitting los ntawm chlorides. Lub alloy yog siv nyob rau hauv me ntsis acidic thiab alkaline tej yam kev mob thiab tuav citric, oxalic thiab phosphoric acids. Stainless hlau CF8M feem ntau yog tib yam li SS 316, F 316 thiab TP 316. Tab sis lawv tau txhais nyob rau hauv cov qauv sib txawv, thiab lawv cov tshuaj thiab cov cuab yeej cuab tam kuj txawv me ntsis thiab. CF8M tau txhais hauv ASMT A351, ASMT A743 thiab ASTM A744, uas yog rau lub hom phiaj casting nkaus xwb. SS 316 yog txhais nyob rau hauv ASTM A240 thiab ASTM A276, nws yog rau phaj, ntawv, sawb lossis stainless hlau tuav. Lwm qib yog lub npe hu ua F316, uas yog los ntawm ASTM A182 rau forged qhov chaw nkaus xwb. TP316 yuav pom hauv ATSTM A376 rau cov yeeb nkab nkaus xwb. Cov ntawv thov tseem ceeb ntawm CF8M cam khwb cia stainless hlau npog: impellers, propellers, twj tso kua mis, valve lub cev thiab xovxwm daim hlau. Kev kho cua sov li niaj zaus rau CF8M yog cov tshuaj daws teeb meem los ntawm cua sov rau ntau tshaj 1900 ° F (1040 ° C), tuav lub sijhawm txaus thiab tom qab ntawd quenching hauv dej los yog txias txias los ntawm lwm txoj kev.

Vim li cas lawv thiaj hu ua CF8M?
Raws li kev tsim, thawj tsab ntawv C txhais tau hais tias qhov kev pabcuam nws yog npaj los siv rau hauv kev pabcuam corrosion resistant, tab sis qee zaum nws txhais tau tias siv CASTING vim koj yuav pom F 316 hauv ASTM A 350 (F = FORGE). Tsab ntawv thib ob F qhia qhov kwv yees qhov chaw ntawm cov hlau ntawm cov hlau-chromium-nickel (FeCrNi) ternary daim duab. Rau cov neeg siv paub txog daim duab, tsab ntawv thib ob muab qhov qhia txog cov ntsiab lus hlau, npib tsib xee, thiab chromium, tab sis feem ntau cov neeg yuav tsum tau txais cov ntaub ntawv alloying los ntawm cov khoom siv tshwj xeeb. Cov tsiaj ntawv thib peb thiab thib plaub 8M sawv cev rau qhov siab tshaj plaws tso cai cov ntsiab lus ntawm 0.01% (piv txwv li, CF8M muaj qhov siab tshaj plaws ntawm 0.08%)
