Taw qhia rau S460NH Hlau Yeeb Nkab
S460ndYog lub siab - lub zog, ua kom zoo ib txwm los yog siv cov khoom siv nplua zoo- nplej cov qauv hlau. Daim qauv tsim ua raws li European txheemEn 10210-1.
S: Sawv rau "qauv" hlau.
460: Qhia txog tusYam tsawg kawg nkaus teev tseg lub zog(Reh) ntawm thicknesses tsawg dua los yog sib npaug rau 16 hli yog460 MPa(lossis n / mmol). Nov yog tus cim tseem ceeb ntawm nws lub zog siab.
N: Qhia tias cov khoom siv tau muab rau hauvzoo li caslos yog coj los ua tus mob. Cov txheej txheem kev kho cua sov no txhim kho kev nruj thiab kho cov qauv zeb.
H: Txhais tau tias cov hlau tsim nyog rauHollow cov ntu(hlab, kav dej).
Cov kav dej no feem ntau siv nyob rau hauv load - Cov kabmob muaj zog thiab vaj txiv ntoo zoo yog qhov tseem ceeb, thiab lwm yam hnyav {} duty {duty duty duty siv khoom siv.
Cov khoom tseem ceeb thiab tshuaj lom neeg sib xyaw ua ke (raws li EN 10210-1)
1. Tshuaj lom neeg sib xyaw ua ke (kev txheeb xyuas teeb tsa -% los ntawm qhov hnyav max.)
Cov muaj pes tsawg leeg yog ua tib zoo tswj kom ua tiav cov khoom siv yam xav tau thiab weldability.

Nco tseg rau lwm cov ntsiab lus:
Lub alloy tej zaum yuav muaj micro -} Alloy} alloying ntsiab xws li niobium (v), lossis titanium (ti) kom ntxiv dag zog rau cov hlau.
Cov pa roj carbon sib npaug (CEV) yog qhov tseem ceeb rau Weldability. Rau s460NH, qhov siab tshaj plaws cev feem ntau txwv kom ntseeg tau tias kev siv vuam zoo. Cov mis yog:
Cua=C + mn / 6 + (cr + mo + v) / {} (ni + cu) / 15(Max. Tus nqi teev nyob rau hauv tus qauv).
2. Cov Khoom Siv Neeg Kho Tshuab
Cov lus hauv qab no qhia txog qhov xav tau yam tsawg kawg nkaus uas yuav tsum muaj cov khoom siv ntsuas kub ntawm chav tsev kub, raws li en 10210-1. Cov khoom tuaj yeem sib txawv me ntsis nrog phab ntsa tuab.
| Ntiag tug | Lub cim | Tus nqi rau nominal phab ntsa tuab (t) | Ib yam |
|---|---|---|---|
| Paib lub zog (min.) | Kub | t tsawg dua lossis sib npaug rau 16 hli: 460 MPa 16 hli MPa (N / MMOL) |
|
| Lub zog tensile | Rm | 550 - 720 mpa | MPa (N / MMOL) |
| Yam tsawg kawg nkaus elongation | A | Sib txawv nrog tuab (piv txwv li, ~ 17% rau t tsawg dua lossis sib npaug rau 40mm) | % |
| Cuam tshuam hluav taws xob (min.) | Kv | Ntau dua los yog sib luag rau 27 joulesntawm-50 degree | Tshav dav hlau |
Cov ntsiab lus tseem ceeb ntawm cov khoom siv neeg kho tshuab:
Lub zog siab:Lub 460 MPa yam tsawg kawg nkaus zog tso cai rau kev sib tw sib zog thiab ntau cov qauv kev tsim qauv rau cov qib qis xws li S355 lossis S275.
Zoo heev qis - kub nruj:Qhov yuav tsum tau ua rau tsawg kawg ntawm 27 Joules ntawm-50 degreeUa rau S460NH haum rau cov ntawv thov hauv cov huab cua txias uas tsis kam rau nkig bitaciture yog qhov tseem ceeb.
3. Cov neeg muaj feem ntev thiab kev ua siab ntev (raws li EN 10210-2)
S460NH Hollow cov ntu yog tsim kom yog ob qho tib sitsis ntsethiabweldedkav dej. Qhov loj me thiab kev ua kom muaj zog (piv txwv li, txheej uas cov taub, phab ntsa tuab, ncaj) yog tswj hwm los ntawm en 10210-2.
Cov Ntawv:Vacular (MS), Square (shs), thiab duab plaub (RHS) hollow seem.
Qauv:Cov txheej txheem tsim khoom ua raws cai rau ib pawg ntawm kev sib raug zoo European Cov Qauv:
En 10210-1:Kev xa khoom mob rau kub -} tiav hollow ntu.
En 10210-2:Taus lav, qhov loj me, thiab cov khoom sib tshooj.

Cov kev txiav txim tseem ceeb rau kev siv
Vuam:Thaum S460NH muaj qhov zoo weldability, nws lub zog muaj zog thiab kev ua haujlwm xav tau cov txheej txheem tsim nyog. Pre ...- cua sov thiab kev siv ntawm kev sib txuam vuam cov khoom siv (}} m
Machining & Txoj Kev:Nws muaj qhov txias txias - Txoj kev ua lub peev xwm.
Corrosion Kuj:S460nd yog ib tug carbon hlau thiab yogtsisStainless. Nws yuav tsum muaj kev tiv thaiv corrosion tsim nyog (piv txwv li, pleev xim, galvanizing tshaj plaws sab nraum zoov lossis kev txhoj puab ib puag ncig lossis kev ua pa.
Rau cov ntaub ntawv teev cov txheej txheem rau ib qhov project tshwj xeeb, nws yog qhov tseem ceeb los sab laj rau tus neeg ua haujlwm EN 10210 thiab daim ntawv pov thawj zeb los ntawm cov hlau tsim khoom.
