Alloy seamless steel yeeb nkab yog cov khoom siv ua haujlwm siab dav siv hauv kev lag luam thiab kev tsim kho. Nws lub ntsiab feature yog los txhim kho cov khoom siv, corrosion kuj thiab kub tsis kam ntawm cov kav hlau steel los ntawm kev ntxiv cov ntsiab lus sib txawv, xws li chromium, molybdenum, npib tsib xee, thiab lwm yam. Cov hauv qab no yog qee cov neeg sawv cev ntawm cov yeeb nkab steel seamless steel:

ASTM A335 Cov Lus Qhia Tshwj XeebP series:

P5: P5 steel yeeb nkab muaj 5% chromium thiab 0.5% molybdenum, muaj oxidation zoo thiab kub lub zog, thiab feem ntau yog siv nyob rau hauv kub kub chav pipelines thiab petrochemical kev lag luam.
P9: P9 steel yeeb nkab muaj 9% chromium thiab 1% molybdenum, muaj ntau dua oxidation tsis kam thiab corrosion kuj tshaj P5, thiab yog haum rau kub thiab siab kub ib puag ncig.
P11: P11 steel yeeb nkab muaj 1.25% chromium thiab 0.5% molybdenum, muaj kev ua tau zoo tshaj plaws, thiab tau siv dav hauv cov kub kub boilers thiab kub exchangers.
P22: P22 steel yeeb nkab muaj 2.25% chromium thiab 1% molybdenum, muaj qhov kub thiab txias zog thiab oxidation tsis kam, thiab feem ntau yog siv rau hauv cov kav dej kub thiab kub siab hauv cov nroj tsuag hluav taws xob thiab kev lag luam petrochemical.
P91: P91 steel yeeb nkab yog lub siab chromium thiab siab molybdenum steel, muaj 9% chromium thiab 1% molybdenum, thiab muaj cov kab ntau ntawm vanadium thiab nitrogen. Nws muaj qhov kub tsis tshua muaj zog thiab lub zog creep thiab yog siv dav hauv cov nroj tsuag supercritical thiab ultra-supercritical fais fab nroj tsuag.
ASTM A 213T series:

T11: T11 steel yeeb nkab muaj 1.25% chromium thiab 0.5% molybdenum, zoo ib yam li P11, thiab feem ntau yog siv nyob rau hauv kub kub exchangers thiab boilers.
T22: T22 steel yeeb nkab muaj 2.25% chromium thiab 1% molybdenum, haum rau qhov kub thiab txias ib puag ncig, thiab yog dav siv nyob rau hauv fais fab nroj tsuag thiab petrochemical industries.
T91: T91 steel yeeb nkab yog tib yam li P91, muaj 9% chromium thiab 1% molybdenum, thiab muaj vanadium thiab nitrogen. Nws muaj lub zog kub kub zoo heev thiab nkag siab tsis kam thiab haum rau cov nroj tsuag supercritical thiab ultra-supercritical fais fab nroj tsuag.
TS EN 10216-2:
10CrMo9-10: Qhov no yog European txheem hlau alloy steel yeeb nkab uas muaj chromium thiab molybdenum, nrog zoo kub kub lub zog thiab corrosion kuj, feem ntau siv nyob rau hauv lub hwj chim nroj tsuag thiab petrochemical industries.
Alloy seamless steel kav zoo heev txhim kho kev ua tau zoo ntawm cov kav hlau los ntawm kev ntxiv cov ntsiab lus tshwj xeeb rau cov hlau, thiab tsim nyog rau ntau yam kev ua haujlwm hnyav. P series thiab T series siab chromium thiab siab molybdenum steel kav, xws li P91 thiab T91, sawv cev rau txoj kev loj hlob ntawm cov niaj hnub kub kub thiab siab siab cov ntaub ntawv thiab yog dav siv nyob rau hauv supercritical thiab ultra-supercritical fais fab nroj tsuag. Xaiv qhov tsim nyog alloy seamless steel yeeb nkab cov khoom siv tsis tau tsuas yog ua kom muaj kev nyab xeeb thiab ruaj khov kev ua haujlwm ntawm qhov project, tab sis kuj tseem txhim kho kev pab cuam lub neej thiab kev ua haujlwm ntawm cov khoom siv.
