Xav txog tias koj tab tom yuav muab qhov kev txiav txim tseem ceeb rau S355J2W Corten Steel. Koj tau tham txog tus nqi thiab lub sijhawm ua haujlwm, tab sis ib lo lus nug tseem ceeb tshaj:Yuav ua li cas koj thiaj paub tseeb tias cov khoom xa tuaj yuav phim cov kev ua tau zoo tau cog lus tseg?Kev cia siab rau tus neeg muag khoom cov lus tsuas yog muaj kev pheej hmoo. Tus yuam sij rau kev ntseeg siab yog nyob rau hauv ib qho yooj yim, tsis yog - cov ntaub ntawv sib tham: tusDaim Ntawv Pov Thawj Mill Test (MTC).
Kab lus no qhia meej meej, kauj ruam -los ntawm- cov txheej txheem pov thawj kom paub tseeb tias Corten Steel koj tau txais yog tiag tiag ua raws thiab haum rau koj qhov project.
Txoj Cai Golden: Xav tau 3.1 MTC
Rau cov khoom siv xws li S355J2W, koj yuav tsum qhia thiab tau txais aHom 3.1 MTC (EN 10204 / ISO 10474). Qhov no tsis yog ib qho yooj yim coj mus muag ntaub ntawv los ntawm distributor. Nws yog daim ntawv pov thawj kev cai lij choj muab ncaj qha los ntawm steel manufacturing mill, muab cov ntaub ntawv pov thawj los ntawm cov khoom siv tiag tiag.
Kev lees txais "daim ntawv pov thawj ntawm kev ua raws" lossis 2.2 MTC tsis txaus. Hais rau daim ntawv pov thawj 3.1-nws yog koj thawj qhov kev lees paub zoo.
Koj daim ntawv txheeb xyuas 4-kauj ruam
Thaum koj tau txais 3.1 MTC, siv daim ntawv tshuaj ntsuam no los xyuas qhov ua tau raws li EN 10025-5 tus qauv rau huab cua steels.
| Kauj ruam pov thawj | Yuav Tshawb Xyuas Dab Tsi ntawm 3.1 MTC | Vim li cas Nws Tseem Ceeb rau S355J2W |
|---|---|---|
| 1. Tshuaj muaj pes tsawg leeg | Pom tseeb feem pua ntawmCu, Cr, Ni, P. Cov no yuav tsum poob rau hauv cov kev txwv nruj ntawm EN 10025-5. | Cov ntsiab lus alloying no yogqhov tseem ceebrau txoj kev tiv thaiv huab cua patina. Kev sib xyaw tsis raug txhais tau hais tias cov hlau yuav tsis huab cua zoo. |
| 2. Mechanical Properties | Txheeb xyuasYield Strength (ReH Ntau dua lossis sib npaug li 355 MPa), Tensile Strength (470-630 MPa), thiab Elongationtus nqi. | Qhov no lees paub qhovstructural kev ncaj ncees. Cov hlau yuav tsum ua kom tau raws li qhov tsawg kawg nkaus lub zog qhov pib ua kom muaj kev nyab xeeb hauv kev thauj khoom. |
| 3. cuam tshuam toughness | Nrhiav qhovCharpy V-Qhov kev ntsuam xyuas cuam tshuam ntawm -20℃(KV-20). Lub "J2" nyob rau hauv S355J2W mandates ib yam tsawg kawg nkaus lub zog nqus. | Qhov no tau lees paub cov hlautiv thaiv brittle puasnyob rau hauv huab cua txias, ib qho tseem ceeb ntawm kev nyab xeeb khoom. |
| 4. Khoom cim npe | Sib phimkub tooj/batch numberntawm daim ntawv pov thawj rau cov cim lub cev ntawm cov hlau phaj lossis ntu. | Qhov notaug cov khoomrov qab mus rau qhov kev xeem ntawv pov thawj, xyuas kom cov ntaub ntawv sib raug rau cov khoom xa tuaj. |
Tom ntej no tsab xov xwm: Kev Ua Haujlwm Zoo Tshaj Plaws
Qhia ntxov: Hauv koj qhov kev thov rau kev hais lus (RFQ) thiab kev yuav khoom (PO), qhia meej meej: "* Cov khoom yuav tsum yog S355J2W (+N) raws li EN 10025-5, muab nrog EN 10204 Hom 3.1 Mill Test Certificate.*"
Tshawb xyuas ua ntej xa khoom xa tuaj: Thov ib daim qauv ntawm MTC los tshuaj xyuasua ntej cov khoom xa tuaj. Qhov no tso cai rau koj los daws qhov tsis sib xws yam tsis muaj qhov project ncua.
Xav txog qhov thib peb -Part Testing: Rau cov phiaj xwm tseem ceeb lossis cov neeg xa khoom tshiab, koj tuaj yeem ntiav ib lub tuam txhab tshuaj xyuas ywj pheej los ua pov thawj los yog ua qhov kev ntsuam xyuas qhov tseeb ntawm cov qauv.
Kev txheeb xyuas S355J2W kev ua raws cai yog kev ncaj ncees tab sis kev qhuab qhia tseem ceeb. Los ntawm kev tswj cov ntaub ntawv kom raug thiab paub yuav ua li cas nyeem nws, koj txav los ntawm kev cia siab rau qhov zooua kom nws. Qhov no tiv thaiv koj qhov project los ntawm kev ua haujlwm tsis ua haujlwm, teeb meem kev nyab xeeb, thiab kev ua haujlwm raug nqi kho mob, kom ntseeg tau tias koj cov qauv Corten Steel yog qhov ruaj khov hauv qhov tseeb raws li nws nyob hauv ntawv.
