SPA-H weathering steel phajyog cov khoom siv hlau uas paub txog nws qhov zoo heev atmospheric corrosion kuj thiab yog dav siv nyob rau hauv fabrication ntawm lub tsev, txuas hniav, tsheb, thiab lwm yam load{0}} bearing lug.
Cov hauv qab no qhia txog kev ua lag luam tiam sis thiab kev loj hlob yav tom ntej ntawm SPA-H weathering steel daim hlau.
Kev Lag Luam Loj Loj
Tsav los ntawm kev loj hlob thoob ntiaj teb kev lag luam thiab kev nthuav dav ntxiv ntawm cov phiaj xwm kev tsim vaj tsev, kev thov rau huab cua steel daim hlau txuas ntxiv nce tsis tu ncua.
Ua tsaug rau nws cov kev tiv thaiv corrosion zoo tshaj thiab ntev - lub sij hawm durability, SPA-H weathering steel ho txo cov nqi tu thiab kev siv lub neej thaum txuas ntxiv kev pab cuam lub neej.
Yog li ntawd, nws tau dhau los ua cov khoom siv ntau dua hauv kev tsim kho, kev thauj mus los, thiab kev siv engineering hnyav.
Kev Txhim Kho Kev Lag Luam Tsis Muaj
Kev lag luam steel tau dhau los ua cov thev naus laus zis txuas ntxiv txhawm rau txhawm rau txhim kho cov khoom siv tau zoo thiab cov khoom lag luam zoo. SPA-H weathering steel daim hlau tau ua kom zoo dua ntxiv kom tau raws li qhov xav tau ntawm engineering xav tau ntau dua.
Los ntawm kev txhim kho alloy tsim, tswj dov, thiab cov txheej txheem ua tiav, ob qho tib si lub zog thiab huab cua tiv thaiv tuaj yeem txhim kho ntxiv, nthuav dav ntawm daim ntawv thov.
Kev sib koom ua ke nrog cov hom phiaj kev loj hlob ruaj khov
Nrog nce thoob ntiaj teb kev paub txog kev tiv thaiv ib puag ncig, kev tsim kho kom ruaj khov tau dhau los ua qhov tseem ceeb hauv kev tsim kho thiab engineering.
SPA-H weathering steel daim hlau muab lub neej ua haujlwm ntev, txo qhov xav tau ntawm cov txheej txheem saum npoo, thiab rov ua dua zoo dua, ua rau lawv ua tau zoo nrog cov tswv yim ntsuab lub tsev.
Yog li ntawd, qhov kev thov rau SPA-H steel yuav tsum tau loj hlob ntxiv hauv ib puag ncig kev paub txog kev tsim vaj tsev thiab kev tsim vaj tsev.
Cov yam ntxwv ua lag luam hauv cheeb tsam
Txoj kev loj hlob ntawm SPA-H weathering steel lag luam txawv raws cheeb tsam, cuam tshuam los ntawm kev lag luam, huab cua, thiab ib puag ncig raug.
Cov cheeb tsam uas muaj huab cua hnyav, cov av noo siab, muaj kuab paug hauv kev lag luam, lossis ib puag ncig hauv hiav txwv zoo li yuav ua rau muaj kev xav tau ntau dua rau corrosion-cov hlau tsis muaj zog.
Cov kev sib txawv hauv cheeb tsam no yuav txuas ntxiv ua kom muaj kev lag luam zoo thiab muaj peev xwm loj hlob ntawm SPA-H weathering steel phaj thoob ntiaj teb.
Zuag qhia tag nrho Market Outlook
Zuag qhia tag nrho, SPA-H weathering steel daim hlau qhia tau hais tias muaj zog ntev - lub sij hawm ua lag luam muaj peev xwm. Kev txhawb nqa los ntawm kev nce kev nqis peev hauv vaj tse, kev ruaj khov - tsav xaiv cov khoom siv, thiab kev siv thev naus laus zis txuas ntxiv mus, lawv daim ntawv thov hauv kev tsim kho thiab kev tsim vaj tsev yuav tsum nthuav dav ntxiv rau xyoo tom ntej.
Spa H khoom yog dab tsi?
Raws li Spa-h steel coil cov khoom yog cov huab cua huab cua, nws tsim cov patina tiv thaiv ntawm qhov chaw uas ua rau nws zoo li rustic. Cov tshuaj muaj pes tsawg leeg ntawm JIS g3125 spa-h strip muaj xws li carbon, silicon, manganese, phosphorus, sulfur, tooj liab, chromium thiab nickel.
Spa-h steel sib npaug yog dab tsi?
Kev sib npaug thoob ntiaj teb ntawm qib SPA-H (Nyiv: JIS ) Hla cov lus siv rau Steel SPA-H (JIS ) thiab nws qhov sib npaug European S355J0WP (1.8945)
Cov tshuaj muaj pes tsawg leeg ntawm SPA-H Steel yog dab tsi?
Cov ntsiab lus tseem ceeb suav nrog carbon (C), manganese (Mn), silicon (Si), chromium (Cr), thiab tooj liab (Cu). Lawv cov ntsiab lus yog tswj nruj me ntsis kom ntseeg tau tias cov khoom siv kho tshuab thiab huab cua tsis kam.
Yuav ua li cas tswj SPA-H Steel?
SPA-H steel yuav tsum tau saib xyuas tsawg kawg nkaus. Ib txheej xeb ruaj khov tiv thaiv cov hlau. Kev tu tsis tu ncua kom tshem tawm cov plua plav lossis cov khib nyiab thiab zam kom tsis txhob raug dej ntev yog txaus.
SPA-H hlau tuaj yeem welded?
Yog lawm. Tsawg-hydrogen arc vuam lossis roj tiv thaiv vuam raug pom zoo. Preheating thiab qeeb txias tom qab vuam pab tiv thaiv kev tawg.
