Tshuaj muaj pes tsawg leeg
| Hom | Cov ntsiab lus tseem ceeb (mass %) | Piv txwv Qib |
| Carbon hlau | C: 0.1–0.45%, Mn: 0.35–1.6%, Si: Tsawg dua lossis sib npaug rau 0.37% | 10#, 20#, 45#, Q345B |
| Hlau alloy | Ntxiv Cr, Mo, V; Piv txwv li, Cr: 0.8-1.1% | 40Cr, 35CrMo |
| Stainless hlau | Cr: Ntau dua lossis sib npaug rau 15%, Ni: Ntau dua lossis sib npaug rau 8%, C: Tsawg dua lossis sib npaug rau 0.08% | 304 (18/8), 316 (16% Cr, 10% Ni, 2–3% Mo) |
| Duplex Stainless hlau | Cr: 20-35%, Ni: 1-15%, N: 0.15-0.4% | Tshwj xeeb rau kev pab cuam offshore thiab qaub |
Mechanical Properties
Lub zog tensile: 450-750 MPa(carbon/low-alloy), mus txog 900+ MPa rau siab- qib zog.
Tawm Zog: 245-690 MPa, nyob ntawm qib thiab kev ua haujlwm.
elongation: Ntau dua los yog sib npaug li 20%, kom ntseeg tau zoo ductility.
Impact Toughness : Qhov tseem ceeb rau qis - kev pabcuam kub; Piv txwv li, Q345D yuav tsum muaj kev ntsuam xyuas ntawm -20℃.
Hardness: Tswj kom tsis txhob tawg; Piv txwv li, HRC Tsawg dua lossis sib npaug li 22 rau qhov chaw pabcuam qaub.
Cov ntawv thov
1.Oil & Gas: Laum kav, casing, tubing, pipelines (tshwj xeeb tshaj yog qaub kev pab cuam nrog H₂S kuj).
2. Fais fab nroj tsuag: High- siab boiler raj, superheater kav.
3.Chemical Industry: Cov hlab ntsha reactor, cov khoom siv hluav taws xob.
4.Mechanical Engineering: Hydraulic cylinders, automotive shafts, bearing vaj tse.
5 .Construction & Infrastructure : Cov qauv kev txhawb nqa, piling.
6.Shipbuilding & Offshore Platforms : Kev thauj khoom tseem ceeb -cov kabmob thiab cov kua dej thauj tshuab.
Vim li cas thiaj xaiv Seamless Yeeb Nkab Chaw tsim tshuaj paus hauv Suav teb?
| Qhov zoo | Kev piav qhia |
| Nqi Efficiency | Tus nqi feem ntau yog 20-30% qis dua li Western cov neeg sib tw, zoo tagnrho rau kev loj - nplai kev yuav khoom. |
| Production Flexibility | Muaj peev xwm ua tau cov khoom me me lossis kev txiav txim loj nrog kev hloov pauv sai (qee qhov muab 36-teev xwm txheej ceev). |
| Technical Maturity | Kev paub txog kub dov, kos duab txias, PQF dov, thiab kev daws teeb meem ua kom muaj kev ntseeg siab thiab kev ntseeg siab. |
| International Ua raws cai | Cov tuam txhab ua lag luam muab Mill Test Reports (MTRs), hydrostatic test , thiab NDT cov ntaub ntawv (UT / ECT), ntsib API, ASTM, thiab GB qauv. |
| Export Npaj | Muaj zog logistics network ntawm cov chaw nres nkoj xws li Qingdao thiab Shanghai ua kom muaj txiaj ntsig zoo thoob ntiaj teb kev xa khoom, tshwj xeeb tshaj yog raws "Belt and Road" txoj kev. |
