A335P92 alloy seamless steel yeeb nkab, kev sib tham tshwj xeeb 48.34 hli, nws tus qauv siv hluav taws xob tuab as335m. Cov hauv qab no yog cov ncauj lus kom ntxaws tshuaj xyuas ntawm cov yeeb nkab steel:
I. Cov txheej txheem yooj yim ntawm cov hlau boiles leeg
A335P92 alloy Seamless steel yeeb nkab yog ib hom zoo siab kub thiab kev kub siab ib puag ncig ntawm cov raj xa hluav taws xob thiab kev rov ua kom sov raj ntawm thipeline ntawm thermal fais fab nroj tsuag. Nws cov khoom siv yog P92, teej tug rau Tebchaws Asmeskas Steel tooj Astm A335 P92 Martensitic Tshav Kub Kub-Resistant Steel.
Thib Ob, Tshuaj Muaj Zog Ntawm Hlau Boiler Hlis
A335P92 alloy seamless steel yeeb nkab tshuaj lom, moladium, chromergen, npib, niobium, tungsten thiab boron thiab boron thiab lwm yam. Cov ntsiab lus tshwj xeeb yog raws li hauv qab no:
Cov pa roj carbon (c): 0.07 ~ 0.13%
Manganese (MN): 0.30-0.60%
Phosphorus (p): ≤0.020%
Sulphur (s): ≤0.010%
Silicon (si): ≤0.50%
Chromium (CR): 8.5 ~ 9.50%
Molybdenum (mo): 0.30 ~ 0.30 ~ 0.50% (tab sis nws yog tsim nyog sau cov ntsiab lus ntawm mo lub ntsiab lus, thiab txhim kho kev ua tau zoo ntawm cov khoom los ntawm kev ntxiv ib qho nyiaj ntawm w)
Vanadium (V): 0.15 ~ 0.25%
Nitrogen (n): 0.03 ~ 0.07%
Nickel (NI): ≤0.40%
Aluminium (al): ≤0.04%
Niobium (NB): ≤0.040 ~ 0.09%
Tungsten (w): 1.5 ~ 2.0%
Boron (b): 0.001 ~ 0.006%
Cov tshuaj tsim nyog ntawm cov ntsiab lus no ua rau A335P92 alloy Seamless steel yeeb nkab tsis kam, ntsuas lub zog kub thiab cov khoom siv kub.
3. Cov khoom siv kho tshuab ntawm cov hlau boiler
A335P92 alloy Seamless steel yeeb nkab muaj cov tshuab zoo dua, uas tau qhia raws li hauv qab no:
Lub zog tensile: ≥620mpa
Peple Zog: ≥440MP
Cov khoom siv no ua kom muaj kev nyab xeeb thiab kev ntseeg tau ntawm cov hlau hlua hauv ib puag ncig kub thiab siab siab.
4. Kev thov teb ntawm hlau boiler leeg
A335P92 alloy seamless steel yeeb nkab vim nws cov yam ntxwv ua tau zoo, yog siv dav hauv cov teb hauv qab no:
Thermal fais fab nroj tshuag: Raws li cov khoom tseem ceeb rau cov raj kav dej loj thiab rov qab ua kom muaj kev nyab xeeb thiab muaj kev nyab xeeb ntawm cov nroj tsuag hluav taws xob.
Petrochemical: Nyob rau hauv tus txheej txheem ntawm cov roj av ua kom zoo nkauj thiab tshuaj lom neeg, nws yog siv rau cov khoom siv hluav taws xob thiab kev kis kom sov thiab lub siab thiab corrosion tsis kam.
Kev lag luam hluav taws xob nuclear lub zog: hauv cov nroj tsuag hluav taws xob nuclear, siv los tsim cov khoom siv tshuab hluav taws xob thiab cov xov xwm ntsig txog kev nyab xeeb thiab ruaj khov ntawm nuclear zog tiam.
5. Kev siv cov qauv thiab xaj cov lus qhia ntawm cov yas boiles steel boiles
A335P92 alloy seamless steel yeeb nkab ua ke nrog ASTM A335 / A335M thawj coj. Thaum xaj, cov ntaub ntawv hauv qab no yuav tsum muaj tseeb:
Kom muaj nuj nqis (piv txwv li hauv ko taw, meters, lossis keeb kwm)
Cov Khoom Siv Npe (Seamless Alloy Steel nomges Yeeb Nkab)
Chav Kawm (P92)
Kev tsim qauv (KUB TOULDED LOS SIS TXAWV)
Cov lus qhia tshwj xeeb (piv txwv li sab nraud ntawm txoj kab uas hla, phab ntsa thickness, thiab lwm yam)
Ntev (muab faib loj thiab loj dua qhov loj)
Kawg Machining
Kev Xaiv Kev Xaiv (EG dej siab thiab pub qhov hnyav sib txawv)
Xav Tau Daim Ntawv Qhia Xav Tau
Tus Qauv Qauv
Cov Kev Xaiv Tshwj Xeeb lossis Ib Yam Yuav Tsum Tau Ntxiv
Hauv cov ntsiab lus, A335P92 alloy Seamless steel yeeb nkab yog lub siab zoo alloy Seamless steel yeeb nkab nrog nws cov cwj pwm zoo heev. Thaum xaj thiab siv, nws yog qhov tsim nyog kom ua raws li cov qauv uas muaj feem xyuam thiab cov tseev kom nws muaj kev nyab xeeb thiab kev ntseeg tau.
