Vim li cas thiaj xaiv S355J0W Steel lossis Corten B Steel?
1. Advanced Welding Performance thiab Versatility
Lub S355 weathering series yog engineered nrog qis carbon sib npaug (CEV), uas yog lub hauv paus ntawm nws cov weldability zoo heev. Cov qib no tau ua tiav nrog txhua tus txheej txheem kev lag luam vuam, suav nrog MIG / MAG (GMAW), TIG (GTAW), thiab Submerged Arc Vuam (SAW).
Vim hais tias cov hlau yog ib qho zoo -qib cov qauv ua tau zoo, nws ua kom muaj kev sib koom ua ke siab tsis muaj kev pheej hmoo ntawm kev ua kom tawv nqaij ntau dhau hauv Heat Afected Zone (HAZ).
Cov kws tshaj lij Precision: Txhawm rau kom cov qauv ua tiav tseem nyob ruaj khov -dawb, cov kws tshaj lij vuam siv cov khoom siv sib xyaw ua ke (muaj 1% Nickel thiab 0.5% Copper). Qhov no ua kom ntseeg tau tias cov hlau vuam tsim muaj kev tiv thaiv patina ntawm tib tus nqi thiab xim raws li lub hauv paus phaj, tiv thaiv "xim los ntshav" lossis hauv zos corrosion.
Kev Tswj Thermal: Rau cov phaj siab tshaj 20mm hauv thickness, preheating (feem ntau ntawm 100℃mus rau 150 degree) yog pom zoo los tswj hydrogen diffusion thiab tshem tawm cov kev pheej hmoo ntawm txias cracking, kom ntseeg tau ib tug txhim khu kev qha, siab - lub zog daim ntawv cog lus uas ua tau raws li cov txheej txheem nruj tshaj plaws.
2. Siab -Precision Txiav thiab Ntug Zoo
Txawm hais tias qhov project xav tau cov qauv zoo nkauj zoo nkauj lossis cov qauv tsim loj heev, S355J / K2W series teb tau zoo heev rau kev txiav thermal. Cov khoom siv cov qauv zoo ib yam tso cai rau kev huv, ntsug npoo nrog tsawg slag adhesion.
Laser & Plasma Txiav: Rau cov ntawv nyias siv hauv cov vaj tsev façades (feem ntau J0W), fiber ntau laser txiav muaj rab chais - ntse precision nrog rau qhov nruj li ± 0.1mm. Rau cov phaj tuab tuab, siab- txhais cov ntshav txiav muab qhov sib npaug zoo meej ntawm kev ceev thiab ntug zoo, tswj xyuas cov khoom siv hlau ntawm cov hlau mus txog rau txoj kab txiav.
Nplaim taws (Oxy- Roj) Txiav: Rau qhov hnyav- cov phaj ua haujlwm feem ntau cuam tshuam nrog qib S355K2W (siv hauv cov khoom siv choj loj), nplaim taws txiav tau zoo heev. Cov ntsiab lus ntawm cov hlau tsis cuam tshuam cov txheej txheem oxidation thaum txiav, uas ua rau kev ua tiav zoo uas yuav tsum tau ua kom tsawg kawg nkaus - txiav kev sib tsoo ua ntej sib dhos.
3. Superior Forming thiab Structure Fabrication
Txawm hais tias nws lub zog muaj zog ntawm 355 MPa, cov tsev neeg hlau no nthuav tawm cov ductility zoo kawg thiab txias - tsim cov yam ntxwv. Nws yog qhov tsim nyog rau kev lag luam dabtsi yog khoov, dov, thiab folding, tso cai rau kev tsim cov txheej txheem kev nkhaus lossis cov txheej txheem nruj.
Cold Bending Logic: Vim nws lub zog siab - rau- qhov hnyav piv, S355 weathering steel yuav tsum muaj zog me ntsis thiab qhov loj me ntsis khoov vojvoog piv rau cov qauv carbon steel los tiv thaiv "caij nplooj ntoos hlav" thiab nto nro tawg.
Fabrication Reliability: Thaum tsim, cov hlau tuav nws qhov kev ruaj ntseg zoo heev. Qhov no ua rau nws nyiam cov khoom siv rau siab -load fabrication qhov twg geometric precision tseem ceeb heev-xws li nyob rau hauv kev tsim kho ntawm lub thawv ntim, railway wagons, thiab loj -scale pej xeem kos duab.
Kev sib xyaw ua ke ntawm nws qhov "J2" lossis "K2" toughness ntsuam xyuas kom ntseeg tau tias txawm tias tom qab kev ntxhov siab ntawm kev tsim, cov khoom tseem muaj zog tiv thaiv kev cuam tshuam thiab qaug zog hauv qhov chaw xav tau tshaj plaws.
