P92 khoom yog dab tsi
Feb 06, 2026
A335 P92 alloy steel yeeb nkabyog ib hom martensitic cua sov-resistant steel dav siv nyob rau hauv siab- kub thiab siab - ib puag ncig siab. Vim nws cov khoom zoo heev, cov khoom siv no ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam.
A335P92 yog ib qho hloov kho 9Cr-1Mo-V-Nb steel, belongs rau martensitic tshav kub-resistant steel qeb. Nws ntxiv optimizes tshuaj muaj pes tsawg leeg ntawm tsoos P91 steel los ntawm kev ntxiv cov ntsiab lus xws li tungsten thiab boron, ho txhim kho cov khoom kub-kub kuj thiab creep zog.
Nyob rau hauv siab - qhov kub thiab txias ib puag ncig, P92 steel muaj oxidation zoo heev thiab corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv kev khiav hauj lwm tej yam kev mob saum toj no 600 degree, qhov twg nws cov kev ua tau zoo yog txawm ntau pronounced. Cov khoom no kuj muaj lub zog tensile siab thiab lub zog tawm los, ua rau nws tiv taus qhov tseem ceeb hauv siab, ua rau nws haum rau siab - cov kav dej siab.
GNEE Group yog cov chaw tsim khoom hauv cov yeeb nkab steel hauv Suav teb, muab cov yeeb nkab kev sib tham thiab kev ua haujlwm.Tag nrho QC cov ntaub ntawv muab: spectral tsom xam + mechanical cuab yeej qhia -txhua batch traceable rau cub tawg tooj.

- Chromium (Cr) 8.5-9.5%: Tsim cov oxide zaj duab xis ntom ntom, txhim kho oxidation tsis kam.
- Tungsten (W) 1.5-2.0%: Hloov qee qhov molybdenum (Mo), ua kom cov molybdenum sib npaug (Mo+0.5W) los ntawm 1% hauv P91 steel mus rau 1.5%, ua kom muaj zog kub kub.
- Boron (B) 0.001-0.006%: Cov kab sib txuas ntxiv ua kom cov kab lis kev cai thiab inhibits qhov kub thiab txias.
- Vanadium (V) 0.15-0.25%, Niobium (Nb) 0.04-0.09%: Cov ntaub ntawv carbide precipitates, ntxiv dag zog rau cov qauv nplej.
- Los ntawm kev sib xyaw ua kom zoo, P92 steel nthuav tawm 20% nce hauv creep zog ntawm 600-650℃piv rau P91, thiab kwv yees li 15% nce hauv kev ntxhov siab, tso cai rau 10-15% txo hauv boiler raj phab ntsa thickness, txo cov khoom hnyav thiab cov nqi tsim khoom.

Smelting thiab Refining:
Lub tshuab hluav taws xob arc rauv + LF refining + VD lub tshuab nqus tsev degassing txheej txheem yog siv los tswj cov sulfur (S) cov ntsiab lus kom tsawg dua lossis sib npaug li 0.010% thiab phosphorus (P) cov ntsiab lus tsawg dua lossis sib npaug li 0.020%, kom ntseeg tau cov khoom siv purity.
Ib lub tuam txhab tshwj xeeb steel hauv tsev tau txo qis kev suav nrog rau ASTM A tus qauv los ntawm kev siv tshuab electroslag remelting, txhim kho cov khoom toughness.
Kub ua hauj lwm thiab kev kho cua sov:
Kub Nruam Rolling Online Quenching: Yas deformation tiav nyob rau hauv qhov kub ntawm 1200-850 degree. Ua ke nrog cov tshuab quenching online, cov nplej loj nce mus txog qib 8 lossis siab dua, kev txhim kho qib 1-2 piv rau cov txheej txheem ib txwm muaj.
Normalizing + Tempering: Cov txheej txheem zoo li qub ntawm 1040-1080℃+ tempering ntawm 760-780 degree, nrog kev tswj qhov kub thiab txias ntawm ± 5 degree. Ib lub tuam txhab tau qhia txog kev txawj ntse kub tswj qhov system, txhim kho kev kho cua sov kom ruaj khov rau 98.5%, thiab ua tiav thoob ntiaj teb qib siab kub nkag lub neej rau nws cov khoom.
Kev kho qhov chaw thiab tshuaj xyuas:
Sandblasting thiab galvanizing txheej txheem yog siv los txhim kho corrosion kuj, thiab 100% cov txheej txheem tshuaj xyuas, nrog rau kev kuaj ultrasonic thiab hydrostatic kuaj, yog ua los xyuas kom meej tias txhua cov yeeb nkab steel tsis muaj teeb meem -dawb.
Daim ntawv thov ntawm A335 P92 Seamless Yeeb Nkab
Vim nws zoo heev - kub lub zog, corrosion kuj, thiab oxidation kuj, A335P92 steel yog dav siv nyob rau hauv cov nram qab no teb:
1.
