L605 cobalt-based superalloy Haynes 25 puag ncig pas nrig tuaj yeem kho tau
L605, tseem hu ua HAYNES25, yog cobalt-based alloy nrog zoo formability thiab high-temperature zog. Nyob rau hauv high-temperature thiab high-zog puag ncig, cov khoom yuav tiv taus oxidation, carbonization, thiab tsis yooj yim rau tawg. L605 HAYNES® 25, UNS R30605, AMS5759F, AMS5537, ASTM F90, AMS 5796
L6{{10}}5 yog cobalt-based alloy nrog zoo formability thiab zoo heev kub kub. Ntawm 1800 degree F, L605 muaj 7000psi, 100-teev kev ntxhov siab tawg lub zog. Ntawm 1900 degree F, L605 tseem tiv taus oxidation thiab carburization Muaj peev xwm. Kev xa tawm ntawm kev kho cua sov kho L605 feem ntau yog nyob rau hauv lub xeev cov tshuaj uas muaj kev ua tau zoo heev. Cov khoom siv qhov ntsuas kub yog 2150-2250 degree F, thiab tom qab ntawd cua txias los yog dej quenched. Cov ntawv nyias nyias nrog lub thickness tsawg dua 0.025 "Kev daws qhov kub thiab txias yog 2150 ° F, tom qab ntawd cua txias los yog dej quenching; daim ntawv thickness 0.026" thiab saum toj no yog qhov kub thiab txias 2200 ° F, ces cua txias los yog dej quenching; Cov phaj tuab tov kub yog 2200 degree F, ces dej quenching; cov khoom kub ntawm lub bar yog 2250 degree F, thiab ces dej quenched. Kev ua haujlwm txias thiab kev laus txhim kho kev ua haujlwm ntawm cov khoom ntawm chav tsev kub thiab cua sov ib puag ncig. Kev ua haujlwm txias kom zoo thiab kev laus kho mob tuaj yeem muab lub zog tensile ntawm cov khoom ntawm chav tsev kub thiab cua sov ib puag ncig. Lub zog. Kev ua haujlwm txias txias tuaj yeem ua rau lub zog nkag mus rau 1800 degree F thiab kev ntxhov siab tawg lub zog mus rau 1500 degree F. Kev laus kub ntau li ntawm 700-1100 degree F. Kev laus tsis tshua muaj txiaj ntsig, tab sis Txhim kho creep thiab tawg lub zog ntawm cov ntaub ntawv hauv qab 1300 degree F.
Kev ua tau zoo
Haynes 25 tuaj yeem ua tiav los ntawm cov txheej txheem ib txwm ua. Nws raug nquahu kom siv cobalt-muaj cov hlau kub ceev lossis hlau hlau txiav cov cuab yeej. Piv nrog austenitic stainless hlau (xws li 304, 321, 347 stainless hlau), Haynes 25 yog qhov nyuaj rau kev ua haujlwm. Lub siab txias ua hauj lwm hardening npaum li cas thiab qhov loj ntawm cov cua sov generated thaum lub sij hawm ua ua hauj lwm nyuaj heev. Nws raug nquahu kom siv cov khoom noj me me thiab ceev ceev.
Vuam
L605 tuaj yeem welded los ntawm shielded hlau arc vuam, roj tungsten arc vuam, thiab roj hlau arc vuam. Submerged arc vuam tsis pom zoo.
Ua ntej vuam, vuam nto yuav tsum tau ntxuav kom huv si, so tawm cov stains thiab qhuav qhov chaw.
Daim ntawv thov
L605 feem ntau yog siv rau hauv kev tsim cov khoom siv dav hlau dav hlau, suav nrog cov cav ntoo, cov khoom siv hluav taws xob, cov khoom siv rov ua dua tshiab, thiab cov turbine rings. L605 kuj tseem siv rau hauv kev lag luam furnaces, nrog rau cov nplaim taws teeb meem thiab cov hauv ob sab phlu hauv qhov tseem ceeb ntawm cov cua kub kub.
Corrosion Resistance
L605 tau pom tias muaj kev tiv thaiv zoo rau kev kub siab corrosive gases hauv kev siv dav hlau dav hlau. oxidation tsis kam ntawm kev ua haujlwm tsis sib xws ntawm 1600 degree F thiab kev ua haujlwm tas mus li ntawm 2000 degree kuj zoo heev. Thaum lub sij hawm cua sov txheej txheem, L605 yog heev resistant rau oxidation thiab tsis muaj cov khoom yuav tshwm sim. Peeling. Nyob rau tib lub sijhawm, cov khoom siv tiv taus ntau yam tshuaj oxidants, tshwj xeeb tshaj yog hydrochloric acid thiab nitric acid ntawm qee qhov concentration thiab kub. Nws muaj kev tiv thaiv zoo rau ntsev tsuag corrosion.
