Q35Sgnh Weathering Hlau Ncej Ua

Q355gnh yog lub siab - Kev Ua Haujlwm Weather Hlau Qib Siab Yuav tsum tau siv hauv cov qauv corrosion tsis kam thiab kev thov kom zoo nkauj. Cov "GNH" nyob rau hauv nws cov qauv sawv ntsug rau "atmospheric corrosion {}} Cov qauv resistant xws li cov ntawv sau ua vaj tse kws ua lag luam, txuas hniav, thiab kev lag luam cov chaw. Hauv qab no yog cov lus qhia ntxaws ntxaws los ua Q355 Wights Wightold hlau thav ntawv, npog cov yam ntxwv, kev kho kom zoo, thiab kev tswj hwm zoo, thiab kev tswj hwm kom zoo, thiab cov kev xaiv zoo.

1. Cov khoom siv ntawm Q355Gnhgh

Tshuaj Muaj Tshuaj:
Muaj cov khoom siv alloy (CU, P, CR, NI) uas txhawb kev tsim cov tuab, ua kom muaj xeb txheej (lub moo plaub) Nyob rau saum npoo, uas inhibits ntxiv corrosion.

Cov khoom siv raug (%): C Tsawg dua lossis sib npaug ntawm 0.12, si 0.25-0.7-0.5- Cu 0.25, Ni tsawg dua lossis sib npaug nrog 0.65.

Cov Khoom Siv Neeg Kho Tshuab:

Tos lub zog ntau dua lossis sib npaug ntawm 355 MPa, tensile lub zog 490-630 MPa, elongation ntau dua los yog sib npaug rau 22%.

Ductility siab thiab cuam tshuam tsis kam, haum rau load - cov kabmob qauv.

Corrosion Kuj:

4-8 zaug ntau corrosion - tiv taus ntau dua li cov pa roj carbon hlau hauv ib puag ncig.

Ua tau zoo nyob rau hauv kev muaj kuab paug, ntug dej hiav txwv (ntsev rau siab), thiab huab cua huab cua huab cua.

2. Cov txheej txheem tseem ceeb rau cov thav ntawv steel

2.1 Txiav

Txojkev:

Laser txiav: Ua tau zoo ± 0.1 mm) thiab cov npoo du, zoo tagnrho rau intricate qauv lossis}} me dua lossis sib npaug rau 20 mm).

Ntshav txiav: Tsim nyog rau cov paib tuab (20-100 mm), sai dua tab sis nrog me ntsis ntxhib sawv. Yuav tsum tau tshaj tawm - kev (sib tsoo) kom tshem tawm slag.

Oxyfuel Txiav: Less common due to potential heat-affected zone (HAZ) oxidation, but usable for thick plates (>50 hli) nyob rau hauv tsis -} tseem ceeb siv.
