Zoo siab - qhov kub thiab txias tsis kam (cov ntsiab lus zoo)
Lub ntsiab kom zoo dua ntawm ASTM A335 P11 nyob rau hauv nws zoo heev high - kub lub zog thiab creep kuj. Ua tsaug rau qhov sib ntxiv ntawm 0.5% molybdenum (Mo), P11 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 450-550℃. Nyob rau hauv 500℃tej yam kev mob, qhov kev cia siab ntawm P11 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 (ntub) ntawm cov ntaub ntawv nyob rau hauv qhov kub thiab txias, ua kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm cov kav dej hauv lub sijhawm ntev - lub sij hawm siab - qhov kub thiab txias. Nrog rau qhov tsawg kawg nkaus tensile lub zog ntawm 415 MPa thiab qhov tsawg kawg nkaus yield zog ntawm 205 MPa, nws ntog nyob rau hauv tus txheej txheem kev ua tau zoo theem ntawm A335 series thiab muaj qhov zoo tseem ceeb ntawm cov nqi-zoo.
Zoo heev vuam kev ua tau zoo thiab kev kho cua sov adaptability
ASTM A335 P11 nthuav tawm kev ua haujlwm vuam zoo, uas yog qhov laj thawj tseem ceeb rau nws txoj kev siv dav hauv kev lag luam hluav taws xob thiab petrochemical. Ua tsaug rau nws cov ntsiab lus nruab nrab ntawm cov alloy thiab cov pa sib npaug (CE), P11 muaj qhov qis dua rau kev ua kom tawv nqaij hauv tshav kub- cuam tshuam thaj chaw (HAZ) ntawm welds. Nws yuav tsum tau ua kom sov me ntsis ua ntej vuam (feem ntau yog 150-250 degree), ua rau nws siv tau-tus phooj ywg rau ntawm- qhov chaw vuam ua haujlwm. Nws cov txheej txheem vuam tau zoo-tsim, nrog cov vuam pom tias nws nyuaj me ntsis, haum rau loj- nplai ntawm - qhov chaw teeb tsa. Tom qab-weld heat treatment (PWHT) yog yuav tsum tau tom qab vuam, uas muaj cua sov mus rau 690-760 degree, tuav ntawm qhov kub thiab txias, thiab maj mam txias kom tshem tawm cov seem welding stresses thiab soften lub tshav kub-cuam tshuam cheeb tsam.
Zoo machinability thiab formability
ASTM A335 P11 nthuav tawm cov khoom txias thiab kub ua haujlwm zoo, tso cai rau ntau yam txheej txheem xws li kub dabtsi yog khoov, txias dabtsi yog khoov, thiab forging. Nws cov ntsiab lus me ntsis alloy muab kev tsim tau zoo thaum lub caij txias txias, ua rau nws tsim nyog rau kev tsim cov yeeb nkab fittings xws li lub luj tshib, tees, thiab reducers. Nws machinability yog piv rau ntawm P1, ua rau kev ua los ntawm cov pa machining txoj kev.
Tus nqi zoo heev -kev ua tau zoo piv thiab sib npaug tag nrho kev ua tau zoo (tsim los ntawm qhov chaw ntawm P1/P22)
ASTM A335 P11 yog qib sib npaug tshaj plaws hauv chromium-molybdenum alloy steel series. Piv rau P1 (0.5Cr{10}}0.5Mo), P11 muaj cov ntsiab lus chromium ntau dua (1.25% vs 0.5%), muab cov oxidation zoo dua thiab siab -kub lub zog. Hauv kev sib piv rau P22 (2.25Cr-1Mo), P11 muaj cov ntsiab lus qis dua, ua rau muaj kev sib txuas zoo dua thiab tus nqi qis dua. Rau cov ntawv thov nrog kev ua haujlwm kub tsawg dua lossis sib npaug li 550 degree, P11 yog tus nqi tshaj plaws - qib chromium-molybdenum steel zoo thiab feem ntau siv chromium-molybdenum steel yeeb nkab hauv cov chaw tsim hluav taws xob thiab kev lag luam refining thoob ntiaj teb.
Lub koom haum zoo ruaj khov thiab ntev - kev cia siab rau kev pabcuam
ASTM A335 P11 qhia txog kev ruaj ntseg zoo thaum nyob ntev - kev pabcuam ntawm qhov kub thiab txias tsawg dua lossis sib npaug li 550℃. Nws 1.25% Cr-0.5% Mo muaj pes tsawg leeg tsim tau zoo txhim kho cov khoom siv siab -kub creep zog thiab oxidation kuj thaum inhibiting pearlite spheroidization thiab carbide coarsening thiab aggregation, kom ntseeg tau tias tus nqi qis ntawm cov cuab yeej degradation thaum lub sij hawm ntev siab {{13.}} kub Tom qab normalization ntxiv rau tempering (N + T) kev kho cua sov, P11 tau txais ib qho zoo thiab zoo ferrite + pearlite microstructure, lav lub koom haum stability thiab kev ntseeg siab nyob rau hauv high-temperature kev pab cuam.

ASTM A335 P11 pom zoo microstructural stability thaum lub sij hawm ntev - kev pab cuam ntawm kub tsawg dua los yog sib npaug rau 550℃. Qhov sib ntxiv ntawm 1.25% Cr-0.5% Mo zoo txhim kho siab - kub lub zog thiab oxidation tsis kam. Txawm li cas los xij, microstructural stability txo thiab creep zog poob qis thaum siv rau ntev -lub sij hawm kev pab cuam saum toj no 580℃; Yog li, nws tsis pom zoo rau kev pabcuam ntev tshaj 580 degree. Rau qib siab dua, P22 lossis P91 raug pom zoo.
Kev kho cua sov
Qhov kev ua tau zoo kawg ntawm ASTM A335 P11 yog nyob ntawm kev kho cua sov, nrog rau cov lus qhia tshwj xeeb raws li 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)
Kub rau 690-760 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
Tshav kub rau 840-890 degree, tuav, tom qab ntawd lub qhov cub 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.
Ceeb toom: Post-weld heat treatment (PWHT) yuav tsum tau ua tom qab vuam. Nws suav nrog cua sov rau690-760 degree , tuav ntawm qhov kub thiab txias, thiab tom qab ntawd maj mam txias kom tshem tawm cov kev ntxhov siab ntawm cov welding residual thiab soften lub tshav kub- thaj tsam cuam tshuam.
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.
