Kev ruaj ntseg cov khoom tsim nyog rau koj qhov project mus dhau qhov kev txiav txim. Thaum muab S235J2W Corten steel los ntawm cov neeg muag khoom nyob sab Europe, xyuas nws txoj kev ua raws cai yog ib qho yooj yim tab sis cov txheej txheem tseem ceeb nyob rau ntawm ib daim ntawv tseem ceeb. Nov yog yuav ua li cas kom ntseeg tau tias koj tau txais raws nraim li koj tau hais tseg.
Txoj Cai Golden: Thov Daim Ntawv Pov Thawj Zeb Xeem (MTC)
CovMill Test Certificate (MTC), tseem hu ua Daim Ntawv Pov Thawj Ua Raws Cai, yog koj li kev cai lij choj thiab cov ntaub ntawv pov thawj ntawm kev ua raws cai. Rau cov hlau uas tswj hwm los ntawm European tus qauv EN 10025-5, MTC (feem ntau hom 3.1) tsis tuaj yeem sib tham. Nws yog muab los ntawm steel mills thiab muab cov ntaub ntawv pov thawj kev xeem rau cov khoom tshwj xeeb uas koj tau txais.
Tsis txhob lees txais daim ntawv xa nyiaj ua lag luam lossis cov lus qhia dav dav ntawm kev ua raws li kev hloov pauv.Nco ntsoov qhia qhov yuav tsum tau ua rau MTC siv tau hauv koj daim ntawv xaj khoom.
Yuav Ua Li Cas Nyeem MTC: Koj Daim Ntawv Pov Thawj Pov Thawj
Thaum koj tau txais MTC, xyuas cov ntaub ntawv tseem ceeb no tiv thaiv EN 10025-5 tus qauv rau S235J2W:
1. Mechanical Properties: Cov Core Strengths
Yield zog (ReH): Yuav tsum yogNtau dua lossis sib npaug li 235 MPa. Nco ntsoov tias rau cov phaj tuab, qhov tsawg kawg nkaus uas yuav tsum tau muaj zog tuaj yeem txo qis me ntsis ntawm tus qauv cov ntxhuav.
Tensile zog (Rm): Yuav tsum poob hauv qhov ntau ntawm360 - 510 MPa.
Elongation (A): Qhov no qhia ductility thiab yuav tsum tau raws li qhov tsawg kawg nkaus feem pua tau teev nyob rau hauv tus qauv (raws li thickness).
2. Qhov Tseem Ceeb "J2" Impact Toughness
Qhov no yog qhov txawv S235J2W los ntawm S235J0W. Koj yuav tsum paub meej tias:
Kev ntsuas kub: Daim ntawv pov thawj yuav tsum tau hais txog qhov kev sim cuam tshuam tau ua ntawm-20 degree.
Impact Zog (KV): Tus nqi ntsuas rau peb cov qauv yuav tsum tau ua kom tau raws li lossis tshaj27 jul(qhov tsawg kawg nkaus yuav tsum tau nruab nrab).
3. Chemical Composition: Daim ntawv qhia rau kev ua tau zoo
Xyuas kom tseeb tias cov feem pua ntawm cov ntsiab lus alloying xws li Phosphorus (P), Copper (Cu), Chromium (Cr), thiab Nickel (Ni) poob rau hauv cov kev txwv los ntawm EN 10025-5. Cov ntsiab lus no yog lub luag haujlwm rau cov hlau huab cua tiv thaiv.
Cov kauj ruam ua tau zoo rau koj txoj kev yuav khoom
Txhawm rau txhim kho kev ua raws cai, sib koom ua ke cov haujlwm no rau hauv koj qhov kev ua haujlwm:
Qhia meej meej hauv koj RFQ / xaj: Xeev: * "Cov ntaub ntawv yuav tsum yog S235J2W raws li EN 10025-5, muab nrog rau hom 3.1 Mill Test Certificate."*
Hla -Xaim thaum xa khoom: Sib phim tus lej xov tooj cua sov lossis batch naj npawb ntawm cov khoom cim npe nrog rau ib qho teev nyob rau hauv MTC. Qhov no txuas lub cev steel rau nws daim ntawv pov thawj.
Xyuas thiab ua ntaub ntawv: Txheeb xyuas MTC tiv thaiv cov ntsiab lus saum toj no. Khaws cia rau hauv cov ntaub ntawv rau lub neej ntawm qhov project- nws yog ib qho tseem ceeb rau kev soj ntsuam zoo thiab kev soj ntsuam tsis ua hauj lwm yav tom ntej.
Xav txog kev txheeb xyuas ywj pheej (Rau cov phiaj xwm tseem ceeb): Rau kev nyab xeeb- cov qauv tseem ceeb (piv txwv li, txuas hniav, cov vaj tse pej xeem), koj tuaj yeem ntiav ib tus thib peb- tog neeg soj ntsuam lub chaw kuaj xyuas cov ntaub ntawv pov thawj lossis ua cov kev kuaj xyuas ywj pheej ntawm cov qauv.
Daim Ntawv Teev Kev Ua Raws Cai Yooj Yim
| Yam khoom kom paub tseeb | Yuav Ua Li Cas Saib Rau ntawm MTC | Kev Cai Txuj Ci (EN 10025-5) |

Los ntawm kev ua Mill Test Certificate lub hauv paus ntawm koj cov txheej txheem kev yuav khoom thiab paub yuav ua li cas txheeb xyuas nws, koj hloov kev ua raws li qhov kev xav rau hauv qhov tseeb. Qhov kev mob siab no ua kom muaj kev ncaj ncees, kev nyab xeeb, thiab ntev -lub sij hawm huab cua kev ua tau zoo ntawm koj daim ntawv thov S235J2W Corten steel.
