Q355 NHByog lub siab -lub zog qis- alloy weathering steel ua raws GB / T 4171-2008, muaj koob npe nrov rau nws qhov zoo tshaj plaws atmospheric corrosion resistance, robust mechanical zog thiab ntau yam txheej txheem. As a cost-effective engineering material, it forms a dense, stable protective rust layer after short-term outdoor exposure, enabling bare use without painting and slashing long-term maintenance costs by 40-60%. Nrog rau qhov tsawg kawg nkaus lub zog ntawm 355 MPa, tensile lub zog ntawm 470-630 MPa thiab 20℃cuam tshuam lub zog Ntau tshaj los yog sib npaug rau 47 J, nws sib npaug siab load-bearing muaj peev xwm thiab txhim khu kev qha toughness, outperforming zoo tib yam carbon steel thiab cov tsoos weathering hlau nyob rau hauv cov yam ntxwv stability.
Qhov zoo ntawm Q355NHB Weathering Steel
Zoo heev Atmospheric Corrosion Resistance
Piv nrog cov qauv carbon zoo tib yam, Q355NHB muaj:
- 2-8 npaug siab dua rau atmospheric corrosion
- Txo cov xeb nkag mus ntev - lub sij hawm raug
- Lub neej ua haujlwm ntev dua nyob rau hauv qhov chaw sab nraum zoov
Qhov no ua rau Q355NHB yog qhov kev xaiv zoo tshaj plaws rau cov qauv tsis muaj xim lossis cov xim me me.
Txhim khu kev qha cov cuab yeej cuab tam
Q355NHB muab qhov sib npaug zoo ntawm lub zog thiab tawv:
- Yield zog: Ntau dua los yog sib npaug rau 355 MPa
- Tensile zog: 470-630 MPa
- Zoo elongation thiab ductility
Cov khoom no ua kom muaj kev nyab xeeb ntawm cov qauv hauv qab static thiab dynamic loads.
Zoo Weldability thiab Fabrication Performance
Q355NHB weathering steel phaj ua tau zoo hauv:
- Welding (nrog rau cov huab cua sib piv cov khoom siv hlau)
- Nplaim taws, plasma, thiab laser txiav
- Txias khoov thiab sib sau
Qhov no tso cai rau cov fabrication npaum li cas yam tsis muaj complex processing.
Lub neej qis dua -Cycle Cost
Ua tsaug rau nws corrosion{0}}cov yam ntxwv tiv taus, Q355NHB:
- Txo lossis tshem tawm qhov xav tau rau kev pleev xim
- Txo cov nqi kho thiab rov ua dua
- Txhim kho tag nrho qhov project economic efficiency
Nws yog tus nqi -kev daws teeb meem zoo rau lub sijhawm ntev - cov phiaj xwm kev tsim kho vaj tse.
