Q355NHB puas tuaj yeem siv nyob rau hauv ib puag ncig marine?

Feb 27, 2026 Tso lus

1. Cov khoom siv yooj yim tso

Q355NHB yog ahigh-strength atmospheric weathering hlau, tsim tshwj xeeb rau cov neeg nyob deb nroog, nroog, thiab kev lag luam dav dav. Nws yogtsis yog ib qho tshwj xeeb marine-qib corrosion-resistant steelthiab muaj cov kev txwv tseeb hauv ib puag ncig uas muaj cov tshuaj chloride siab, tshuaj tsuag ntsev, thiab dej hiav txwv.

2. Cov xwm txheej raws li Q355NHB tuaj yeem siv rau hauv thaj chaw marine

Nws tuaj yeem siv rau hauvme me ntug dej hiav txwv atmospheric aavuas nyob deb txaus los ntawm ntug dej hiav txwv, nrog tsawg ntsev tsuag concentration thiab tsis muaj kev sib cuag ncaj qha nrog dej hiav txwv.

Hauv cov cheeb tsam no, Q355NHB tsim kev tiv thaiv patina thiab ua haujlwmzoo dua li cov pa roj carbon zoo tib yamzoo q355b.

Nws tuaj yeem siv raucov vaj tse nyob hauv ntug dej hiav txwv, cov chaw nres nkoj pabcuam, thiab cov khoom tsis muaj kev thauj khoomuas tsis raug cua ntsev hnyav los yog dej hiav txwv txaws.

Yog siv nrogxim, txheej, los yog kev tiv thaiv saum npoo, nws cov kev pab cuam lub neej nyob rau hauv ib puag ncig me me ntug dej hiav txwv tuaj yeem txuas ntxiv mus.

3. Marine ib puag ncig uas Q355NHB tsis haum

Splash tsam: Cov cheeb tsam feem ntau cuam tshuam los ntawm seawater nthwv dej thiab txaws, qhov twg chloride ions ua rau pitting corrosion sai.

Tidal cheeb tsam: Alternating ntub thiab qhuav raug dej hiav txwv rhuav tshem lub ruaj khov patina thiab accelerates cov khoom degradation.

Submerged tsam: Kev sib cuag ncaj qha thiab mus sij hawm ntev nrog dej hiav txwv yuav ua rau muaj kev xeb sai thiab hnyav heev.

Heavy marine cua: Cov chaw ntug dej hiav txwv uas muaj cua muaj zog, muaj ntsev ntau, thiab cov av noo siab, feem ntau ntawm cov chaw nres nkoj, cov chaw nres nkoj, thiab cov vaj tse sab nrauv.

Hauv cov cheeb tsam hnyav no, Q355NHB tsis tuaj yeem tsim cov txheej txheem tiv thaiv zoo thiab yuav raug kev txom nyem los ntawmaccelerated structural deterioration.

4. Sib piv nrog cov ntaub ntawv qib marine tiag tiag

Dedicated marine weathering steels thiab seawater-resistant alloy steels muaj ntau dua cov ntsiab lus ntawm chromium, npib tsib xee, tooj liab, thiab lwm yam, muab ntau zog tiv thaiv chloride corrosion.

Q355NHB tsis muaj cov alloy muaj pes tsawg leeg uas yuav tsum tau tiv thaiv cov dej ntsev thiab dej hiav txwv ntev, yog li nws tsis tuaj yeem hloov cov qib kev ua haujlwm marine.
