Zoo siab - qhov kub thiab txias tsis kam (cov ntsiab lus zoo)
Lub ntsiab kom zoo dua ntawm ASTM A335 P1 nyob rau hauv nws nruab nrab siab - kub lub zog thiab creep kuj. Ua tsaug rau qhov sib ntxiv ntawm 0.5% molybdenum (Mo), P1 nthuav tawm qhov ua tau zoo tshaj qhov siab tshaj -kub creep rupture zog piv rau cov pa roj carbon zoo tib yam (xws li A106 Gr.B) nyob rau hauv qhov kub ntawm 350-500℃. Nyob rau hauv 450℃tej yam kev mob, qhov kev cia siab ntawm P1 yog kwv yees li 1.5 mus rau 2 npaug ntawm cov pa roj carbon steel, ua rau nws ua tau zoo tiv thaiv cov yas deformation qeeb (rub) ntawm cov ntaub ntawv nyob rau hauv qhov kub thiab txias, ua kom muaj kev ruaj ntseg thiab kev cia siab ntawm cov kav xa dej thaum lub sij hawm ntev - lub sij hawm siab - kub. Nws lub zog tensile yam tsawg kawg nkaus yog 415 MPa thiab qhov tsawg kawg nkaus tawm lub zog yog 205 MPa, uas yog cov qib kev ua tau zoo nyob rau hauv A335 series tab sis muaj cov txiaj ntsig tseem ceeb ntawm cov nqi-zoo.
Kev ua haujlwm vuam zoo heev thiab kev kho cua sov adaptability (differentiated kom zoo dua)
Kev ua haujlwm vuam ntawm ASTM A335 P1 yog qhov zoo dua li ntawm P11 thiab P22, uas yog ib qho tseem ceeb rau nws txoj kev xaiv raws li kev ua haujlwm tshwj xeeb. Ua tsaug rau nws cov ntsiab lus qis qis thiab cov pa roj carbon sib npaug (CE), P1 muaj qhov sib npaug me dua rau kev ua kom tawv tawv hauv vuam kub- thaj tsam cuam tshuam, yuav tsum tau ua kom qis qis dua ua ntej vuam (feem ntau 100-200 degree), ua rau nws siv ntau dua -tus phooj ywg rau ntawm - qhov chaw vuam ua haujlwm Tshwj xeeb tshaj yog nyob rau hauv nyias- cov ntawv thov cov yeeb nkab phab ntsa thiab cov xwm txheej uas tom qab-weld kev kho cua sov tsis tuaj yeem ua tiav tam sim ntawd, P1 nthuav tawm qhov ua tau zoo dua rau qhov txias tawg piv rau qib siab - alloy. Nws cov txheej txheem vuam zoo ib yam li cov pa roj carbon zoo tib yam, ua rau kev ua haujlwm qis dua rau cov welders, ua rau nws haum rau loj - nplai ntawm qhov chaw teeb tsa.
Zoo machinability thiab formability
Cov khoom ua haujlwm txias thiab kub ntawm ASTM A335 P1 zoo dua rau cov P11 thiab P22, tso cai rau ntau yam txheej txheem xws li kub dabtsi yog khoov, txias dabtsi yog khoov, thiab forging. Nws cov ntsiab lus qis qis txo qhov kev pheej hmoo ntawm kev tawg thaum lub caij txias khoov, ua rau nws tsim nyog rau kev tsim cov yeeb nkab fittings xws li lub luj tshib, tees, thiab reducers. Tsis tas li ntawd, nws cov machinability yog zoo dua li ntawm siab -alloy chromium-molybdenum steels, zoo txo nqi machining.
Tus nqi - qhov kev pom zoo muaj txiaj ntsig zoo (tshwj xeeb los ntawm qhov chaw ntawm P11 / P22)
ASTM A335 P1 yog qib nrog cov ntsiab lus alloy qis tshaj plaws thiab tus nqi qis tshaj ntawm ib chav tsev qhov hnyav hauv chromium-molybdenum alloy steel series. Piv rau P11 (1.25Cr{14}}0.5Mo), P1 muaj cov ntsiab lus chromium tsuas yog 0.5% (kwv yees li 40% ntawm P11), uas ua rau txo cov nqi hlau alloy. Rau cov ntawv thov uas qhov ntsuas kub ua haujlwm tsawg dua lossis sib npaug li 450℃thiab tsis tas yuav muaj kev tiv thaiv oxidation ntau dua, P1 ua haujlwm zoo li -tus nqi hloov pauv rau P11 / P22, muab cov khoom siv nyiaj txuag nyiaj ntau thaum tuav lub zog kub.
Lub koom haum muaj kev ruaj ntseg zoo thiab ntev - kev cia siab rau kev pabcuam
ASTM A335 P1 pom zoo microstructural stability thaum lub sij hawm ntev - kev pab cuam ntawm kub txog li 500℃. Qhov sib ntxiv ntawm 0.5% Mo ua tau zoo txhim kho cov khoom siv siab -kub creep lub zog thaum inhibiting pearlite spheroidization thiab carbide coarsening, kom ntseeg tau tias tus nqi qis ntawm cov cuab yeej cuab tam degradation ntev ntev - kub kev pab cuam. Tom qab normalization ntxiv rau tempering (N + T) kev kho cua sov, P1 tau txais ib qho zoo thiab zoo ferrite + pearlite microstructure, lav microstructural stability thiab kev ntseeg siab nyob rau hauv siab - kub kev pab cuam tej yam kev mob.

Ntev -Lub sij hawm Thermal Stability thiab Microstructural Stability:
ASTM A335 P1 pom zoo microstructural stability thaum lub sij hawm ntev - kev pab cuam ntawm qhov kub thiab txias tsawg dua los yog sib npaug li 500℃. Qhov sib ntxiv ntawm 0.5% Mo zoo txhim kho siab -kub creep zog. Txawm li cas los xij, thaum siv rau lub sijhawm ntev tshaj 550 degree, nws qhov kev ruaj ntseg microstructural txo qis thiab creep zog poob qis; yog li, nws tsis pom zoo rau kev ua haujlwm ntev - lub sijhawm ua haujlwm siab tshaj 550℃. Rau qib siab dua, P11 lossis P22 raug qhia.
Kev kho cua sov
Qhov kev ua tau zoo kawg ntawm ASTM A335 P1 yog nyob ntawm kev kho cua sov, nrog rau cov lus qhia tshwj xeeb hauv qab no:
1. Kev Kho Mob (Normalizing):
Tshav kub rau 900-955 degree, tuav lub sijhawm txaus (kwv yees li 1 teev ib nti ntawm phab ntsa tuab), ces cua txias. Qhov no ua rau muaj kev sib txuam zoo ferrite + pearlite microstructure, npaj nws rau tom ntej tempering.
2. Tempering kho(Tempering):
Tshav kub rau 620-750 degree, tuav lub sijhawm txaus, ces cua txias. Qhov no tshem tawm kev ntxhov siab vim los ntawm normalizing, optimizes toughness thiab ductility, thiab ua tiav cov kev pab cuam zaum kawg.
3. Tag Nrho Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas:
Tshav kub rau 870-900 degree, tuav, tom qab ntawd rauv txias kom txog li 650 degree, tom qab ntawd cua txias rau chav tsev kub. Siv los tshem tawm kev ntxhov siab ua haujlwm txias lossis txhim kho kev ua haujlwm txias.
Nco ntsoov:
Post-weld heat treatment (PWHT) raug pom zoo tom qab vuam. Nws suav nrog cua sov mus rau 620-750 degree, tuav ntawm qhov kub thiab txias, thiab tom qab ntawd maj mam txias kom tshem tawm cov kev ntxhov siab uas seem thiab ua rau thaj chaw muaj kev kub ntxhov.
Kev kho cua sov kub thiab lub sij hawm yuav tsum tau tswj nruj me ntsis kom tsis txhob muaj cov nplej coarsening lossis kev ua haujlwm hloov pauv.
Rau nyias - cov raj phab ntsa lossis cov raj me me - txoj kab uas hla, lub sij hawm rwb thaiv tsev tuaj yeem ua kom luv luv.
