ASTM A588 qib b corten steel daim hlauyog dav siv nyob rau hauv kev tsim qauv zoo nkauj vim lawv qhov siab - Lub zog qauv, thiab muaj txiaj ntsig zoo nkauj patinetic. Hauv qab no yog ib qho ntxiv hauv - qhov kev piav qhia tob txhawb kev txhawb nqa los ntawm cov ntaub ntawv txheej txheem.
1. Cov qauv siv hauv kev siv toj roob hauv pes
A588 Gr.B steel provides reliable mechanical performance and can bear significant loads, making it ideal for landscape structures such as retaining walls, planters, benches, edging, and pedestrian bridges.
Cov qauv txheej txheem kev ua tau zoo
| Ntiag tug | Nruab Nrab Hlau Hlau (Q235) | A588 qib b |
|---|---|---|
| Paib lub zog | 235 MPa | 345 MPa |
| Lub zog tensile | 370-500 mpa | 485-620 mpa |
| Atmospheric corrosion | Qi | 3-5 × siab dua |
➡ Ua tsaug rau nws cov txiaj ntsig siab dua tawm lub zog (345 MPa), A588 Gr.B tuaj yeem txo cov phaj tuab los ntawm 10-20%, txo qis cov khoom siv thiab tsheb thauj mus los.
Txo cov kev xav tau kom muaj cov txheej txheej saum npoo ntxiv kuj tseem txo cov nqi zog los ntawm 70% hla lub neej dhau los.
2. Toj roob hauv pes paving
A588 gr.b steel feem ntau yog siv rau av paving panels, taug kev taug kev, stair cos, thiab façade Cladding.
Thaum raug rau cov cua, nws ua rau cov yeeb yaj kiab oxide ruaj khov li ntawm 6-24 2}} brown chocolate xim av - xim av.
Cov ntaub ntawv ua haujlwm saum npoo
| Lub sij hawm raug | Cov xim nto | Patina stability |
|---|---|---|
| 1-3 lub hlis | Lub teeb xeb (txiv kab ntxwv) | Tsis ruaj |
| 3-9 lub hlis | Nruab nrab xim av | Semi - nyob ruaj khov |
| 9-24 lub hlis | Sib sib zog nqus daj | Cov Txheej Txheem Ruaj Ntseg |
| 2+ xyoo | Tsaus xim av / purplish | Ua kom muaj kev ruaj khov |
➡ Cov khaub ncaws hnav thiab nthav sib txhuam ntawm paving qhov chaw thiab muab ntev {- Cov yam ntxwv swb.
➡ sib haum nrog cov khoom siv xws li ntoo, pob zeb, qhob, thiab iav, muab cov tsim tsim muaj kev yooj yim dua.
3. Toj roob hauv pes duab puab thiab kos duab sib xyaw
A588 Qib B yog dav xaiv rau kev pom zoo niaj hnub vim nws cov plasticity vim nws cov plasticity, weldability, thiab cov huab cua zoo nkauj.
Vim li cas A588 Gr.B yog qhov zoo rau cov duab puab
Cov hlau cov vinity tso cai rau kev sib tsoo txias, laser txiav, thiab kev ua yeeb yam.
Cov kev tswj hwm corrosion tsim tsim ib xeb, kev lag luam, vintage zoo nkauj.
Qhov sib sib zog nqus, matte nto tshem tawm cov iav ntsej muag, txhim kho qhov pom kev.
Ntev - Lub tob corrosion ntawm tsuas yog 10-25 μm / xyoo tom qab Sculptures tseem nyob ruaj khov.
4. Vim li cas A588 B yog li nrov tshaj plaws hauv kev tsim toj roob hauv pes
| Yam zoo | Nyiaj Pab |
|---|---|
| Siab atmospheric durability | Patina txo cov nqi corrosion los ntawm 60-80% |
| Tus nqi saib xyuas tsawg | Tsis muaj kev pleev xim yuav tsum → lub neej them nqi txo los ntawm 70-80% |
| Ncees actisce stability | Ntuj Kev Hloov Chaw Hloov Kho Kev Zoo Nkauj |
| Eco - tus phooj ywg | Pes Tsawg Voc emissions los ntawm cov xim |
| Lub Neej Muaj Kev Pab Ntev | 2-3 × ntev nyiaj txiag tiv thaiv cov hlau dog dig |
| Txheej Txheem Kev Nyab Xeeb | High paib lub zog zog ua kom muaj kev ruaj khov rau cov khoom siv toj roob hauv pes |
Nrog nws lub zog, durability, ntuj ntawm kev saib xyuas rustic, nws tsis muaj qhov xav tau ntawm cov ntawv uas nyiam tshaj plaws hauv kev tsim qauv niaj hnub hauv kev tsim khoom zoo nkauj niaj hnub no.
Lawv muab kev cia siab rau kev ua lag luam thiab cov yeeb yam zoo tshaj plaws rau cov chaw ua si sab nraum zoov, chaw ua si, kev ua lag luam plazas, thiab ua lag luam plazas, thiab ua lag luam plazas, thiab ua lag luam plazas
