A588 yog cov huab cua qib hauv qab Astm tus qauv.Weathering hlau hais txog hom qes-alloy uas tau txais cov tshuab hluav taws xob tsawg tsis kam los ntawm kev sib ntxiv ntawm cov khoom siv me me. Nws yog dav siv thoob ntiaj teb.
✅ 1. Tshuaj lom neeg sib xyaw (hauv qhov hnyav%)
| Lub ntsiab | A588 Qib A | A588 qib b | Sau ntawv |
|---|---|---|---|
| Carbon (c) | Tsawg dua los yog sib npaug rau 0.19 | Tsawg dua los yog sib npaug rau 0.20 | |
| Manganese (mn) | 0.80–1.25 | 0.75–1.35 | |
| Phosphorus (p) | Tsawg dua los yog sib npaug rau 0.04 | Tsawg dua los yog sib npaug rau 0.04 | |
| Sulphur (s) | Tsawg dua los yog sib npaug rau 0.05 | Tsawg dua los yog sib npaug rau 0.05 | |
| Tooj Liab (Cu) | Ntau dua los yog sib npaug rau 0.20 | Ntau dua los yog sib npaug rau 0.20 | Qhov tseem ceeb rau huab cua |
| Chromium (cr) | 0.40–0.65 | 0.40–0.70 | |
| Npib tsib caug (ni) | Tsawg dua los yog sib npaug rau 0.40 | Tsawg dua los yog sib npaug rau 0.40 | |
| Silicon (si) | 0.15–0.50 | 0.15–0.50 |
NCO TSEG: Qhov tseem ceeb yuav sib txawv me ntsis nyob ntawm phaj tuab thiab cov chaw tsim khoom.
Los ntawm kev ntxiv cov ntsiab xws liTooj liab, chromium, thiab npib tsib xeeRau qhov dog dig-alloy steel, lub corrosion kuj yog txhim kho. Cov khoom siv hluav taws xob tiv thaiv hluav taws xob tiv thaiv hlau2 txog 8 zaugtias ntawm tib neeg cov pa hlau, thiab ntev dua nws nthuav tawm rau cov huab cua, ua tau zoo dua kev tiv thaiv Patina tiav.
✅ 2. Cov Khoom Siv Neeg Kho Tshuab
| Ntiag tug | Qhov toob kas |
|---|---|
| Paib lub zog | Ntau dua los yog sib npaug rau 50 ksi (345 MPa) - rau tsawg dua lossis sib npaug nrog 100 mm tuab |
| Lub zog tensile | Ntau dua los yog sib npaug rau 70 ksi (485 MPa) - rau tsawg dua lossis sib npaug nrog 100 mm tuab |
| Elongation (hauv 200 hli) | Ntau dua los yog sib npaug rau 18% |
| Elongation (hauv 50 hli) | Ntau dua los yog sib npaug rau 21% |
✅ 3. Cov yam ntxwv tseem ceeb
- Cov atmospheric zoo heev corrosity tsis kam (4-8x zoo dua li cov roj carbon)
- Ua cov txheej xeb xeb uas txo kev txij nkawm
- Feem ntau siv nyob rau hauv cov choj, cov tuam tsev, yees, thiab cov tsheb ciav hlau tau raug rau cov chaw sab nraud
✅ 4Cov. Cov ntawv thov ntawm A588 Steel Phaj:
Cov qib xws liA588Gra, A588GRB, thiab A588GRCmuaj feem ntau siv nyob rau hauvwelded, bolted, thiab riveted txheej txheem kev thov, tshwj xeeb tshaj yog qhov hnyav txo lossis txuas ntxiv lub neej yog qhov xav tau - xws li hauvTxuas hniav thiab vaj tse.
Cov hlau no muaj ntau cov atmospheric corrosion tsis kam dua li cov hlau txheem nrog lossis tsis muaj tooj liab, tshwj xeeb thaum lub sijhawm qhib cua. Nws yog qhov haum rau kev siv hauvliab qab (unpainted) tej yamHauv ntau cov xwm txheej, suav nrog:
- Tsuas thiab Siv Machineryxws li hnyiab, hluav taws xob shovels, pob tseg truck, mining truck, excavators, loaders, tsoo lub tsheb loj, thiab cranes
- Coaline Mine EquipmentZoo li kev txhawb nqa hydraulic
- Lwm cov txheej txheem txheej txheemRaug rau cov chaw hnyav
- Cov chaw ua hauj lwmZoo li sab nraum zoov tos
- Welded Steel qauvsiv nyob rau hauv huab cua hnyav
Nrog nws cov huab cua zoo heev, lub zog muaj zog, thiab lub sijhawm ntev,ASTM A588 Weathering Hlauyog qhov kev xaiv zoo tshaj plaws rau kev siv sab nraum zoov raug rau cov chaw hnyav. Seb koj lub tsev txuas hniav, kev lag luam machinery, lossis kev xaiv cov khoom zoo yog qhov tseem ceeb rau kev ua tau zoo thiab thiav.
