1. Cov Khoom Siv Txheej Txheem
ASTM A588 Huab Cua Hlau Beams yog siab- Lub zog, qis}}}}}}} {{{) thaum raug rau cov atmospheric. Qhov no tus kheej - Tiv thaiv cov yam ntxwv ntawm cov hlau ua kom zoo dua piv rau cov roj carbon monoxial), 2-4x kev txhim kho kom muaj kev pab cuam lub neej.
2. Cov ntsiab lus tseem ceeb
Atmospheric corrosion: Cov ntawv ib qho kev ua kom xeb uas muaj xeb ntxiv corrosion
Lub zog siab - rau - qhov hnyav} qhov hnyav. Piv: 50 Ksi (345 MPa) Yam tsawg kawg nkaus kom muaj zog
Txheej Txheem Kev Ntseeg: Tswj cov khoom siv tshuab hluav taws xob hauv qhov ntsuas kub hnyav (-20℃f to +150℃f)
Kev daws kev daws teeb meem: Tshem tawm yuav tsum muaj cov tshuaj tiv thaiv kev tiv thaiv / pleev xim rau hauv feem ntau cov chaw ib puag ncig
3. Tshuaj lom neeg cov khoom siv tshuaj xyaw
| Lub ntsiab | Kev Sib Tw | Cov nyhuv huab cua |
|---|---|---|
| CU | 0.20-0.40% | Txhim kho corrosion tsis kam |
| Cr | 0.40-0.65% | Txhab kev tiv thaiv Patina |
| Ni | 0.25-0.40% | Txhim Kho Kev Muaj tawv |
| P | 0.04% Max | Pab rau PATINA tsim |
4. Cov Khoom Siv Neeg Kho Tshuab
Peple Zog: 50 Ksi (345 MPa) min
Lub zog tensile: 70 ksi (483 mpa) min
Elongation: 21% min hauv 8 "
Charpy V - nech cuam tshuam: 20 ft - lb ntawm -10℃f
5. Txheem Khoom Specifications
Qho tseem ceeb: W4 × 13 rau W36 × 300 (txheem dov ntu)
Ntev: Txog li 60 '(kev cai ntev muaj)
Nplaim: Zeb teev ua tiav (tsis them), txhaj tshuaj tiv thaiv, lossis ua ntej {- huab cua kev xaiv
