1. Cov ntaub ntawv: 1.4903 steel (x8cronimovnb16-13)
Tus lej1.4903yog tus lej ntawm covDin (Lub koom haum German rau cov qauv)thiabEn (European qauv)Cov Qauv. Nws yog martensitic stainless hlau tsim feem ntau rau qhov siab-} kub kev pab.
Cov npe ntawm cov npe:Nws yog feem ntau raug xa mus los ntawm nws cov kev tsim qauv zoo ib yamX8cronimovnb16-13.
Cov yam ntxwv tseem ceeb:
Siab - kub lub zog:Nws thawj qhov txiaj ntsig yog nws muaj peev xwm tswj hwm cov kev siv tshuab zoo (lub zog nkag) nyob rau ntawm 650℃(1200℃f).
Corrosion Kuj:Muaj qhov zoo tsis kam mus rau oxidation thiab scaling ntawm qhov kub.
Microstructure:Nws yog martensitic steel, lub ntsiab lus nws tuaj yeem ua tau nyuaj los ntawm kev kho cua sov (quenching thiab tempering) kom ua tiav nws cov khoom uas koj xav tau.
2. Cov Khoom: Seamless Yeeb Nkab
"Seamless" txhais tau tias yog cov yeeb nkab yog tsim los ntawm cov khoom haum cylindrical cov hlau billet. Lub billet yog rhuab thiab chob los ntawm lub chaw kom tsim lub raj hollow tsis muaj nqaws lossis welds.
Qhov zoo ntawm cov kav dej seamless:
Ntau dua siab ncaj ncees:Qhov tsis muaj ntawm Weld Seam ua rau lawv muaj zog dua thiab txhim khu kev qha rau cov kev thov siab siab- qhov kev siv siab.
Cov ris tsho sib luag:Ntau txuas nrog phab ntsa tuab thiab lub zog nyob ib ncig ntawm tag nrho cov ncig.
Kev ntseeg tau:Tsawg pheej hmoo ntawm cov ntsiab lus tsis ua tiav, ua rau lawv zoo tshaj rau cov ntawv tseem ceeb.
3. Cov Ntawv Thov Tib Neeg
Vim nws cov khoom, 1.4903 Seamless Steel kav yog siv nyob rau hauv kev xav tau cov khoom lag luam, feem ntau:
Lub zog tiam:SuperHeater thiab Rabe rabes kab, thiab lwm qhov tseem ceeb kav dej hauv thee {{}} reced thiab biomass fais fab nroj tsuag.
Petrochemical Kev Lag Luam:Nyob rau hauv qhov cub, hloov kho dua tshiab, thiab lwmy - cov chav ua haujlwm kub.
Aerospace:Tej siab - kub cov khoom siv.
4. Cov Qauv Txheej Txheem thiab Cov Lus Qhia Tshwj Xeeb
Cov yeeb nkab no yog tsim raws li cov qauv hauv ntiaj teb uas txhais tau tias nws qhov ntev, kev ua kom muaj kuab lom, thiab cov khoom siv kho mob.
Qauv Qauv:EN 10216 {- 5 (Seamless Tubes Rau Siab Lub Hom Siab - Stainless Hlau Hlab)
Cov Qauv Dimension:
En / din:En 10216-5 feem ntau hais txog cov qauv nyob ruaj khov zoo liDIN 2448lossisEn ISO 1127rau sab nraud diameters thiab phab ntsa thicknesses.
ASME / ASTM:Hauv Asmeskas, ib qib zoo sib xws los yog sib luag yuav raug siv, xws li cov neeg hauv ANTM A213. Tsis muaj ib qho ncaj qha astm sib npaug, tab sis nws poob rau hauv qeb ntawm creep {{1}- ua rau cov hlau ferritic ferritic.
5. Cov yam ntxwv tseem ceeb (cov nuj nqis)
Tshuaj lom neeg tshuaj lom neeg (kwv yees li):
Cov pa roj carbon (c): ~ 0.08%
Chromium (CR): ~ 15.5-16.5%
Nickel (NI): ~ 12.5-13.5%
Cobalt (CO): ~ 2.5-3.5%
Molybdenum (mo), Niobium (NB), Vanadium (V) tseem yog cov ntsiab lus tseem ceeb.
Cov cuab yeej kho tshuab (ntawm chav sov, tom qab kev kho cua sov):
Tensile lub zog: ntau dua los yog sib npaug rau 700 MPa
Paib lub zog: ntau dua los yog sib npaug rau 450 MPa
Elongation: ntau dua los yog sib npaug rau 18%
Lub ntsiab
Hauv ntej, a1.4903 Seamless Steel Yeeb NkabYog lub siab - kev ua tau, weld - free raj ua los ntawm cov chromium dawb- nplua nuj steel. Nws yog engineered kom muaj kev tiv thaiv huab thiab siab kub (txog ~ 650 degree) ntev li cas, ua rau nws lub zog tseem ceeb ntawm cov khoom siv hluav taws xob ntau tshaj plaws thiab cov chaw ua haujlwm siv tshuaj lom neeg.
Thaum sourcing cov khoom no, nws yog qhov tseem ceeb los qhia cov qauv uas yuav tsum tau (piv txwv li (sab nraud ntawm kev siv cua sov
