Qhov sib txawv ntawm S355J0W steel thiab S355J0WP steel

Thaum xaiv siab -lub zog huab cua steel daim hlau, ob qho tib siS355J0W steel hlauthiab S355J0WP steel yog dav siv raws li EN 10025-5 tus qauv.

Cov qib no feem ntau hu ua Corten- hom hlau, tsim los tsim cov txheej tiv thaiv oxide (patina) uas tiv thaiv kev xeb ntxiv.

S355J0W steel hlau

Txawm li cas los xij, txawm tias zoo li corrosion kuj, lawv cov tshuaj muaj pes tsawg leeg, weldability, thiab thickness muaj peev xwm txawv heev. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau kev nyab xeeb ntawm cov qauv thiab kev ua haujlwm ntev ntev -.

Ntawm Gnee Steel, peb muab cov ntawv pov thawj S355J0W steel daim hlau thiab cov qib huab cua cuam tshuam rau lub ntiaj teb kev tsim kho vaj tsev, choj, thiab kev tsim vaj tsev.

S355J0W Steel Phaj (EN 10025-5)

Sib npaug rau Corten B-hom Weathering Steel
S355J0W ua hauj lwm raws li niaj hnub European metric sib npaug rau cov classic Corten B. Thaum nws qhia tib yam atmospheric corrosion kuj zoo li Corten A, nws cov tshuaj muaj pes tsawg leeg tau hloov kho tshwj xeeb (qis Phosphorus, siab dua Manganese) los txhim kho cov qauv hauv cov nplej. Qhov no ua rau nws "qib kev lag luam" ntawm weathering steels, muab qhov sib npaug txhim khu kev qha ntawm chemistry thiab mechanical zog.

Tsim los rau cov phaj tuab thiab cov khoom siv hnyav hnyav
Tsis zoo li lwm cov huab cua huab cua uas poob kev ncaj ncees thaum lawv tau tuab dua, S355J0W yog metallurgically optimized rau cov ntsuas hnyav (feem ntau ntawm 12mm mus rau ntau tshaj 200mm).

Nws tuav lub zog sib npaug ntawm 355 MPa txawm nyob rau hauv cov ntu loj. Qhov no yog qhov tseem ceeb rau kev tsim vaj tsev nyob qhov twg cov khoom siv yuav tsum txhawb nqa cov neeg tuag siab (qhov hnyav ntawm cov qauv nws tus kheej) thiab cov khoom nyob (tsheb los yog cua) ntev ntev.

Kev ua tau zoo heev hauv Welded Structures thiab Load-Bearing Components
Qhov zoo tshaj plaws ntawm S355J0W yog nwssuperior weldability. Los ntawm kev ua kom Phosphorus qis, cov hlau tsis txhob "kub tawg" thaum lub sij hawm vuam txheej txheem.

Qhov no tso cai rau cov engineers siv nws rau kev thauj khoom tseem ceeb- cov kabmob sib koom ua ke, xws li cov uas pom nyob rau hauv tus choj girders, railway wagons, thiab siab - nce ncej.

Nws yog tsim los daws "kev ntxhov siab qaug zog"- rov qab thauj khoom thiab tshem tawm cov voj voog ib txwm ntawm cov txheej txheem- yam tsis tau tsim cov qauv micro- tawg.

S355J0WP Steel Phaj (EN 10025-5)

Sib npaug rau Corten A-hom Weathering Steel
S355J0WP yog qhov ncaj qha European sib npaug rau Corten A, thawj huab cua hlau. Nws tau lees paub thoob ntiaj teb raws li tus qauv kub rau atmospheric tsis kam.

Nws raug xaiv tshwj xeeb thaum "ntev" ntawm qhov chaw thiab "ceev" ntawm patina tsim yog qhov tseem ceeb tshaj qhov tuab ntawm cov phaj steel.

Cov ntsiab lus phosphorus siab dua (Cov Tiv Thaiv Catalyst)
Cov yam ntxwv ntawm cov qib no yog nws qib Phosphorus siab dua (txog 0.15%). Metallurgically, Phosphorus reacts nrog tooj liab thiab Chromium los tsim ib tug ntom, "impenetrable" oxide txheej (patina) sai dua li cov qauv hlau.

Cov txheej no ua raws li cov ntaub thaiv npog subterranean, sealing lub hauv paus hlau tiv thaiv ya raws thiab oxygen, zoo nres cov txheej txheem corrosion hauv nws cov lem.

Zoo dua rau cov ntawv nyias nyias thiab daim ntaub ntawv façade
Vim tias S355J0WP tsim cov txheej txheem nruj thiab zoo nkauj zoo nkauj, nws yog qhov kev xaiv zoo dua rau nyias - ntsuas cov ntaub ntawv (feem ntau yog 1mm txog 10mm). Nyob rau hauv architectural façades, nws muab ib tug niaj hnub, sib sib zog nqus -xim av velvet zoo nkauj.

Nws kuj tseem yooj yim dua rau laser- txiav rau hauv cov qauv zoo nkauj rau cov ntxaij vab tshaus zoo nkauj, kos npe, thiab kos duab pej xeem yam tsis muaj warping lossis poob nws cov kev tiv thaiv zoo ntawm qhov txiav.

Kev siv txwv tsis pub siv Hnyav Welding Structures
Thaum S355J0WP tiv taus xeb heev, nws cov ntsiab lus Phosphorus siab ua rau nws "kub luv"- txhais tau tias nws tuaj yeem ua rau qhov kub thiab txias uas yuav tsum tau ua rau hnyav - lub luag haujlwm vuam. Yog tias siv rau hauv tuab, ntau- hla cov pob qij txha welded, muaj kev pheej hmoo siab dua ntawm cov vuam tsis ua haujlwm lossis tawg.

Yog li ntawd, nws feem ntau txwv rau kev siv kho kom zoo nkauj, lub teeb thav duab thav duab, lossis bolted sib dhos es tsis yog qhov tseem ceeb, siab -kev nyuaj siab welded infrastructure.

Lub ntsiab kev sib txawv ntawm S355J0W thiab S355J0WP steel daim hlau nyob hauv phosphorus (P), carbon (C), thiab silicon (Si), uas ncaj qha cuam tshuam rau weldability thiab thickness kev ua tau zoo.

Cov ntsiab lus P siab dua hauv S355J0WP steel → zoo dua atmospheric xeb tsos tab sis tsis muaj zog weldability

Cov ntsiab lus P qis hauv S355J0W steel → zoo dua cov qauv kev nyab xeeb thiab kev ua haujlwm zoo

✔ S355J0W Steel - Superior Weldability

Lub hauv paus yog vim li cas engineers qhia S355J0W dhau qib "P" yog nws cov tshuaj ua kom zoo dua qub, tshwj xeeb txog Phosphorus qib.

Lub Metallurgy ntawm Weldability: S355J0W muaj phosphorus qis dua S355J0WP. Phosphorus siab tuaj yeem ua rau "kub luv," qhov twg cov hlau ua nkig ntawm qhov kub thiab txias, ua rau micro- tawg hauv pas dej ua ke. Los ntawm kev ua kom Phosphorus qis, S355J0W ua kom lub tshav kub raug cuam tshuam (HAZ) nyob twj ywm thiab muaj zog.

Zoo tagnrho rau Choj Vuam Structures: Loj - nplai txuas txuas yuav tsum loj, ntau- hla welds. S355J0W tso cai rau kev sib sib zog nqus welds uas tuaj yeem tiv taus cov thermal stresses ntawm cov txheej txheem vuam yam tsis muaj kev cuam tshuam rau lub hauv paus hlau txoj kev ncaj ncees.

Railway Cheebtsam & Hnyav Fabrication: Hauv kev tsim cov tsheb thauj khoom thiab cov khoom hnyav, vuam yog thawj txoj kev koom ua ke. S355J0W muab kev txhim khu kev qha, tawg - tiv taus qhov chaw uas tau sib xws nrog cov qauv siab - lub zog vuam khoom siv.

✔ S355J0W Steel - Thickness Flexibility

Thaum S355J0WP tau txais txiaj ntsig zoo rau cov ntsuas nyias (feem ntau hauv qab 12 hli) vim nws cov chemistry, S355J0W tau tsim kho los tswj nws cov khoom siv tshuab thoob plaws ntau qhov tuab.

Txhawb Ultra-Thick Phaj (100mm+): Ntau qhov siab -load tej yaam num yuav tsum tau phaj siab tshaj 50mm, 80mm, los yog txawm 100mm nyob rau hauv thickness. S355J0W yog tsim los kom nyob twj ywm "homogeneous"- txhais tau tias lub zog ntawm lub hauv paus ntawm cov phaj tuab yog ze li zoo ib yam rau lub zog ntawm qhov chaw.

Tsim nyog rau Loj -Ib qho chaw tsim khoom: Hauv tej yaam num xws li kev loj overpasses los yog maritime qauv, nyias nyias tsis tuaj yeem muab lub sij hawm tsim nyog ntawm inertia lossis load- muaj peev xwm. S355J0W tso cai rau cov engineers los ntsuas qhov "ntau" ntawm cov qauv thaum khaws cov huab cua tiv thaiv.

High-Load Engineering Ib puag ncig: Los ntawm lub tsev ntau pob ru tsev mus rau hnyav- lub luag haujlwm muaj silos, muaj peev xwm siv tuab -section weathering steel tso cai rau kev tsim kho ntawm "tus kheej- tiv thaiv" cov qauv uas tsis tas yuav muaj kev cuam tshuam ntawm cov txheej txheem cuam tshuam nrog thinner, ntau qib nkig.

✔ S355J0W Steel - Cov qauv kev ntseeg tau

Kev ntseeg tau ntawm cov qauv tsis yog tsuas yog tuav qhov hnyav xwb; nws yog hais txog yuav ua li cas cov khoom coj tus cwj pwm nyob rau hauv kev ntxhov siab, kev co, thiab kub hloov ntau xyoo lawm.

Ntau txoj hauv kev koom nrog: S355J0W tshwj xeeb yog tsim los ua raws li ntau yam kev sib dhos, suav nrog vuam, siab - nro bolting, thiab riveting. Nws cov qauv hauv cov nplej yog qhov muaj zog txaus los tswj cov "clamping quab yuam" hauv zos ntawm bolts yam tsis muaj kev ntxhov siab -corrosion cracking.

Siab Fatigue Resistance Nyob rau hauv Dynamic Loads: Tsis zoo li cov tsev zoo li qub, cov qauv zoo li cov choj thiab cov kab tsheb ciav hlau yuav raug "cov khoom hnyav"- tsis tu ncua kev co thiab qhov hnyav hloov. S355J0W muaj lub zog qaug zog siab, txhais tau tias nws tuaj yeem tiv taus ntau lab ntawm "kev nyuaj siab" yam tsis muaj hlau ua "nkig" lossis ua rau tsis ua haujlwm sai.

Impact Toughness (J0 Rating): Qhov "J0" hauv nws lub npe qhia tias cov hlau tau raug sim los tiv thaiv qhov cuam tshuam tsawg kawg nkaus ntawm 27 Joules ntawm 0 degree.

Qhov no ua kom ntseeg tau tias txawm tias nyob rau lub caij ntuj no txias, cov hlau tseem "nruj" es tsis yog "nkim," tiv thaiv kev puas tsuaj puas tsuaj nyob rau hauv kev cuam tshuam tam sim lossis kev thauj khoom hnyav.
