Q355Gnh Weathering hlau, tseem hu ua atmospheric corrosion {{1} {{{2} {} Cov hlau tsis txaus ntseeg uas zaum ntawm cov nqe lus ntawm kev sib xyaw thiab kev ua tau zoo.
Q355gnh hlau yog ua los ntawm kev ntxiv cov nyiaj me me ntawm corrosion - Cov khoom lag luam loj xws li tooj liab thiab npib tsib xee rau cov carbon hlau.
Q sawv cev muaj zog.
355 qhia tias qhov qis qis cov txiaj ntsig hluav taws xob tsis muaj zog ntawm cov hlau hauv N / MM².
GNH sawv rau cov atmospheric corrosionance.
Tus qauv rau Q355 huab cua huab cua - Cov hlau tiv taus yog GB / T 4171 {{2008. Q355Gnh Weathering hlau tuaj yeem muab rau hauv ntau hom ntawv, suav nrog kub- rolled, tswj-dov, lossis ib txwm muaj.

Cov Khoom Siv
Q355GNH Weather Resistant Steel has excellent rust resistance, high corrosion resistance, and benefits such as thinning, reduced consumption, labor savings, and energy efficiency.
Nws corrosion kev txhim kho yog cuam tshuam ntau dua los ntawm kev ntxiv cov tooj liab me me thiab npib tsib xee, ua rau nws zoo tshaj plaws rau ntev-}}}}}}}}}}}}}} lub sij hawm raug rau atmospheric.
Q355Gnh Weathering Steel yog dav siv hauv kev lag luam ntau yam, suav nrog:
RAILWAY: Rau cov ciav hlau ciav hlau, txuas hniav, thiab cov tunnels, qhov twg ruaj khov. Tus hlau lub tensile lub zog (ntau dua los yog sib npaug ntawm 355 MPa) thiab elongation (ntau dua los yog sib npaug ntawm 20%) kom nws tuaj yeem ua kom hnyav thiab muaj kev ntxhov siab.
Cov tsheb: siv rau ntawm cov hlau seem rau kev thauj mus los zoo li tsheb, thiab cov tsheb thauj khoom, qhov chaw siab ntawm kev saib xyuas yog qhov tseem ceeb.
Txuas hniav: ib txwm muaj nyob rau hauv Choj kev tsim kho, Q355gnh tuaj yeem tiv thaiv cov mob hnyav vim tias nws lub siab tiv taus cov atmospheric corrosion. Cov hlau yog cuam tshuam -} TUAB AT -20 DEGREE, kom ntseeg tau yooj yim txawm tias huab cua txias.
Yees: Hauv kev sib txuas lus cov ntawv, hluav taws xob kis cov kab, Q355Pegnh cov nqi zog thiab cov khoom kho tsis zoo rau cov qauv txheej txheem nthuav tawm.
Cov qauv hlau: siv nyob rau hauv cov tsev hlau, vov tsev, thiab facades, mus txog 490 MPa tsis xav tau rau kev xav tau rau cov txheej txheej lossis kev kho mob.
Ntim rau hydrogen corrosive media: vim nws corrosion tsis kam, Q35gnhgh yog siv nyob rau hauv kev tsim khoom ntawm cov thawv ntim thiab ntim cov tshuaj rau cov khoom siv hydrogenive rau lwm cov ntaub ntawv.
Tus qauv rau Q355ngnh yog GB / T 4171-}}} xyoo 2008, ua kom lawv ua tau zoo rau huab cua kom ua haujlwm rau huab cua-ua tau zoo thiab cov qauv kev cai.
