1. Dab tsi yog s355j {2}} w?
S355J {0} w yog huab cua hlau phaj, uas yog rau European tus qauv qib thiab txoj kev siv cov qauv yog en {2}}: 2004. Nws ntxiv ib qho me me ntawm corrosion-resistant eleptant xws li tooj liab thiab npib tsib xee thiab muaj kev ua tau zoo hauv ntau yam.
2. Dab tsi yog qhov ua yeeb yam ntawm s355j {2}} w?
Atmospheric corrosion: Nws tuaj yeem tsim cov yeeb yaj kiab tuab ntawm cov npoo hlau kom tiv thaiv corrosion yam xws li ya raws, oxygen thiab kuab kuab nyob rau hauv cov huab cua. Cov atmospheric corrosion yog 2-8 lub sij hawm uas ntawm cov carbon hlau, thiab muaj kev pab cuam lub neej ntev.
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab: Nws muaj cov yam ntxwv ntawm cov hlau zoo xws li muaj zog, muaj kuab, kev puas tsuaj, kub ua rau muaj kev kub ntxhov. Cov txiaj ntsig lub zog yog saum 355mpa, lub zog tensile yog siab dua 580MPA, thiab lub elongation tom qab loj dua los yog sib npaug rau 20%.
Vuam kev ua haujlwm: Nws tuaj yeem txuas los ntawm ntau txoj kev vuam txoj kev xws li arc vuam, roj vuam, thiab kev tawm tsam vuam.
Kev cuam tshuam tawv: Thaum qhov kev cuam tshuam kub yog 0 degree, qhov cuam tshuam loj dua los yog sib npaug ntawm 31J, uas tuaj yeem tiv thaiv cov qauv kev ruaj khov thiab kev nyab xeeb
3.Yog cov khoom tuaj yeem hloov nws?
Q355Nth, kuj muaj cov huab cua hlau, muaj cov tshuaj lom neeg thiab cov khoom siv neeg kho mob uas yuav luag sib npaug rau S355J {2}} w.
4.as huab cua-tiv thaiv cov yeeb nkab, yog muaj cov kav dej seamless?
Feem ntau, ob lub ntiaj teb cov hlau yog nyob rau hauv daim ntawv ntawm cov phaj hlau, yog li lawv feem ntau welded kav dej.
5.Aplation scenarios ntawm huab cua hluav taws xob kav hlau
Weathering steel muaj cov atmospheric zoo heev, cov khoom siv zoo, ua tau zoo heev thiab kev cuam tshuam zoo heev. Nws yog dav siv hauv cov qauv steel uas tau tshwm sim rau cov cua ntev, xws li kev tsheb nqaj hlau, cov tsheb nqaj hlau, photovoltacs, thiab high-ceev cov haujlwm.
