s355j2w+n phaj yog dab tsi? nws siv qhov twg?

S355J2W + N yog ib qho tshwj xeeb huab cua qib steel nrog ib qho ntxiv ntawm npib tsib xee (N) hauv nws cov tshuaj muaj pes tsawg leeg. EN 10025 5 s355j2w n phaj qhia tau hais tias huab cua zoo dua qub piv rau tus qauv S355J2W.

Yog li, nws yog qhov zoo dua rau cov qauv sab nraum zoov uas raug mob hnyav ib puag ncig.

S355J2W + N phaj tsim muaj kev tiv thaiv patina ntawm nws qhov chaw uas txo qhov kev xav tau ntawm kev saib xyuas thiab pleev xim.

Weathering steel S355J2W + N phaj tuaj yeem siv rau hauv txuas hniav, facades, ntim, tsheb ciav hlau thiab cov khoom siv. Lawv cov khoom zoo li huab cua tsis kam thiab lub zog siab txhim kho lawv lub neej ntev thiab kev ua haujlwm.

 

Dab tsi yog qhov sib npaug ntawm cov khoom siv S355J2?

Qhov sib npaug ntawm S355J2 EN 10025-2 yogASTM A572 Qib 50, DIN ST52-3, JIS SM490YA, thiab GB Q355D, nrog lub zog zoo sib xws thiab qis -kub toughness rau kev siv cov qauv. GNEE steel lub siab - cov phaj zoo ua kom ua raws li koj cov haujlwm. Yog xav paub ntxiv, tshawb xyuas peb cov ntaub ntawv qhia qib BS EN 10025-2.

 

S355j2w+n VS S355j2+n

S355J2W + N strips cov ntaub ntawv yog huab cua qib steel nrog txhim kho atmospheric corrosion kuj vim qhov sib ntxiv ntawm Ni. Nws yog tshwj xeeb yog siv rau sab nraum zoov daim ntaub ntawv uas raug rau huab cua hnyav.
S355J2+N yog cov khoom siv hlau tsis yog hlau siv rau cov qauv siv dav dav. Nws muaj qis dua ntawm kev tiv thaiv corrosion piv rau S355J2W + N coils.

 

Puas yog S355J2W tib yam li Corten B steel?

Yog, xyaum hais lus.Corten Byog ib tug zoo-paub lub npe lag luam, thaumS355J2Wyog tus qauv European official (TS EN 10025-5) rau structural weathering steel.
Ob qib sib koom yuav luag zoo tib yam tshuaj muaj pes tsawg leeg (nplua nuj nyob rau hauv tooj liab, Chromium, thiab Nickel) thiab muab tib yam 355 MPa yam tsawg kawg nkaus yield zog thiab zoo heev atmospheric corrosion kuj. Yog tias koj cov duab kos duab kos duab qhia Corten B, koj tuaj yeem ntseeg siab siv peb S355J2W raws li daim ntawv pov thawj tag nrho, kev lees paub thoob ntiaj teb sib npaug.

 

Vim li cas lub phaj zoo li dub / grey es tsis txhob xeb? Nws siv sijhawm ntev npaum li cas los tsim cov txiv kab ntxwv / xim av patina?

Los ntawm lub neej ntawd, peb daim hlau S355J2W tau xa hauv'raws li -rolled' mob, txhais tau tias lawv muaj qhov tsaus grey zeb nplai ntawm qhov chaw, ib yam li cov hlau qub. Kev tiv thaiv, xeb-zoo li patina ib txwm ua dhau los6 mus rau 18 lub hlisthaum raug hloov pauv huab cua ntub thiab qhuav sab nraum zoov.
Tus nqi-Kev Pabcuam Ntxiv: Yog tias koj qhov project architectural xav tau qhov zoo nkauj tam sim ntawd 'rusty' saib, peb kuj muabua ntej -kev kho qhov chaw xeb (ua kom huab cua nrawm)hauv peb qhov chaw ua haujlwm ua ntej ua zaub mov xa tuaj.

 

Peb puas tuaj yeem vuam S355J2W siv tus qauv me me hlau vuam electrodes?

Thaum S355J2W yog welding heev, pebtawm tswv yim tawm tsamsiv tus qauv me me steel consumables.
Txhawm rau kom ntseeg tau tias lub vuam seam muaj tib lub cua sov tiv thaiv corrosion thiab nws thiaj li phim cov xim ntawm cov phaj huab cua, koj yuav tsum siv.weathering-qib vuam consumables(xws li ER80S-G los yog sib npaug xov hlau uas muaj Cu thiab Ni). Kev siv cov xov hlau txheem yuav ua rau cov pob qij txha txuas rau corrode sai dua li lub phaj nws tus kheej, cuam tshuam cov qauv kev nyab xeeb. Peb tuaj yeem muab qhov sib txuam vuam hlau nrog rau koj qhov kev txiav txim steel phaj.

 

Kuv qhov project yog nyob rau thaj tsam txias. Koj ua li cas lav qhov qis -kub toughness ntawm S355J2W?

Lub npe 'J2' qhia meej meej lav qhov ua tau zoo tshaj plaws hauv sub-zero ib puag ncig. Thaum lub sij hawm ntau lawm, peb nruj me ntsis ua tusCharpy V-Kev ntsuas qhov cuam tshuam ntawm -20℃(ua kom zoo dua lossis sib npaug rau 27 Joules). Tsis tas li ntawd, kev ua tib zoo tswj qhov sib ntxiv ntawm Nickel (Ni) hauv peb cov S355J2W chemistry ua rau nws muaj zog tiv thaiv kev tawg hauv cov huab cua txias. Tag nrho cov txiaj ntsig kev xeem tau sau tiav hauv cov ntawvEN 10204 3.1 MTC.

 

Lub sij hawm ua rau cov dov tshiab S355J2W ntev dhau lawm rau peb lub sijhawm ua haujlwm. Koj puas muaj tus nqi nrawm dua lossis ntau dua - lwm txoj haujlwm zoo?

Yog, kiag li. Yog tias koj qhov project ncua sij hawm nruj thiab pab pawg engineering pom zoo cov qauv sib npaug, peb xav kom Suav qib sib npaug:Q355 NHD(NH sawv cev rau Huab cua, D sawv cev rau -20℃cuam tshuam kev xeem).
Q355NHD muab covraws nraim tib yam yield zog, qis-kub toughness, thiab huab cua tsis kam Performance indexyog S355J2W. Qhov tseem ceeb tshaj, peb khaws cov khoom npaj loj ntawm Q355NHD hauv Suav ports, cia peb thauj koj cov khoom thauj hauv7-10 hnubntawm tus nqi sib tw heev piv rau European zeb cov sijhawm.
