Yog tias koj tab tom xav txogS355J2W Corten Steelrau koj qhov project, nkag siab txog nws txoj kev ua raws li cov qauv kev cai yog qhov tseem ceeb rau kev ua haujlwm, kev nyab xeeb, thiab kev pom zoo tshwj xeeb. Cov lus teb luv luv thiab meej yog:
Yog lawm, S355J2W yog qib tseem ceeb uas tau teev tseg thiab tswj hwm los ntawm EN 10025-5 European tus qauv rau huab cua-resistant structural steels.
Kab lus no yuav qhia meej tias tus qauv no txhais li cas, vim li cas qhov kev ua raws cai no tseem ceeb rau koj qhov project, thiab yuav ua li cas qhia cov khoom kom raug.
Kev nkag siab EN 10025-5: Tus Qauv Ntsuas rau Huab Cua Huab Cua
EN 10025-5 yog ib feem ntawm cov txheej txheem dav dav ntawm European cov qauv rau cov khoom siv hlau kub-dov. Part 5 yog tshwj xeeb rau"Wathering Steels."
Nws lub hom phiaj tseem ceeb yog txhawm rau txheeb xyuas qhov yuav tsum tau ua ntawm cov txheej txheem steel uas ua kom muaj kev tiv thaiv corrosion ntawm atmospheric los ntawm kev tsim cov patina tiv thaiv. Kev ua raws cai lav peb qhov tseem ceeb:
Tshuaj muaj pes tsawg leeg: Nws qhia meej meej meej rau cov ntsiab lus alloying xws li Phosphorus, Copper, Chromium, thiab Nickel, uas yog qhov tseem ceeb rau kev tsim cov khoom ruaj khov, tus kheej - tiv thaiv xeb txheej.
Mechanical Properties: Nws teem caij tsawg kawg nkaus rau kev tawm dag zog, lub zog tensile, thiab elongation, ua kom muaj kev ncaj ncees. Rau S355J2W, qhov no txhais tau hais tias qhov tsawg kawg nkaus yield zog ntawm 355 MPa (rau thicknesses tsawg dua los yog sib npaug rau 16 hli).
Technical Delivery Conditions: Nws qhia txog qhov yuav tsum tau ua rau kev tsim khoom, kuaj, tshuaj xyuas, thiab cov ntaub ntawv.
Daim ntawv ceev tab sis tseem ceeb:Lub npe raug yogS355J2W. Lub "355" qhia txog nws qhov tsawg kawg nkaus tawm lub zog hauv MPa. Lub "J2" qhia nws qhov kev cuam tshuam qhov hnyav ntawm -20 degree, thiab "W" sawv cev rau "Weathering."
Tus nqi tsim nyog ntawm kev ua raws li koj qhov project
Kev qhiaS355J2W rau EN 10025-5tsis yog ib qho kev ua haujlwm nkaus xwb; nws muab cov txiaj ntsig zoo ntawm qhov project:
Guaranteed Performance & Kev nyab xeeb: Nws muab lub hauv paus txhim khu kev qha, tus qauv tsim rau cov kws tsim qauv ua haujlwm ua haujlwm suav nrog thiab tsim qauv nrog kev ntseeg siab. Koj paub tseeb tias nws muaj peev xwm tiv taus huab cua thiab nws lub zog muaj zog.
Streamlined Procurement & Quality Assurance: Thaum koj tso qhov kev txiav txim xa mus rau "S355J2W raws li EN 10025-5," nws tshem tawm qhov tsis meej pem. Cov ntawv pov thawj zeb xeem (MTCs) los ntawm cov neeg tsim khoom muaj koob npe yuav txheeb xyuas kev ua raws li txhua qhov yuav tsum tau ua ntawm tus qauv, ua kom muaj kev kuaj xyuas zoo.
Kev lees paub thoob ntiaj teb & Kev lees txais: Tus qauv EN tau lees paub dav thiab lees paub hauv kev tsim kho thoob ntiaj teb thiab kev tsim kho vaj tse, ua kom yooj yim cov txheej txheem pom zoo nrog cov tswj hwm thiab cov neeg siv khoom.
Yuav ua li cas kom ntseeg tau tias koj tau txais cov khoom raws cai
Txhawm rau kom ua tiav qhov kev ua raws li kev coj ua, ua raws li cov kauj ruam no:
Qhia Precisely: Hauv koj cov ntaub ntawv kev sib tw lossis kev yuav khoom, ib txwm hais tag nrho cov npe:S355J2W (+ N) raws li EN 10025-5.Qhov "+N" qhia txog kev ua haujlwm zoo li qub, uas yog tus qauv xa khoom.
Thov Mill Certificate: Ib txwm xav tau tus nomEN 10204 Hom 3.1 Mill Test Certificatelos ntawm koj tus neeg muag khoom. Qhov no yog cov ntaub ntawv kev cai lij choj uas ua pov thawj cov ntaub ntawv ua raws li tus qauv, uas qhia cov tshuaj ntsuam xyuas thiab cov khoom siv tshuab los ntawm kev tsim cov zeb.
Nkag siab lub npe lag luam: "Corten B" yog ib lub npe lag luam rau cov hlau uas ua tau raws li S355J2W specification. Thaum feem ntau siv sib hloov, rau kev cog lus kom pom tseeb, tus qauv tsim (S355J2W) yog ib txwm nyiam thiab tsis meej pem.
Hauv cov ntsiab lus,S355J2W yog ua raws li EN 10025-5, raws li nws yog cov khoom tseem ceeb ntawm tus qauv heev. Qhov kev ua raws cai no yog koj qhov kev lees paub ntawm cov khoom siv uas muaj kev ntseeg siab ua ke nrog cov qauv siv zog nrog kev ruaj khov, tsis tshua muaj -cov yam ntxwv ntawm kev saib xyuas huab cua. Rau qhov project ua tiav, ib txwm hais rau tus qauv no hauv koj qhov kev qhia tshwj xeeb thiab txheeb xyuas nws nrog daim ntawv pov thawj zeb nrog.
