1. Taw qhia
CCS Qib Ayog ahlau me medav siv nyob rau hauv shipbuilding, pom zoo los ntawm lubTuam Tshoj Classification Society (CCS). Nws ua hauj lwm raws li ib tuggeneral - hom phiaj steelrau cov hulls, decks, thiab tsis yog - cov khoom tseem ceeb uas lub zog siab tsis yog qhov tseem ceeb.
2. Mechanical Properties
Yield zog: Ntau dua lossis sib npaug li 235 MPa
Tensile zogUa haujlwm siab: 400-520 MPa
Elongation (%): Ntau dua lossis sib npaug rau 22 (L=5d)
Impact Zog: Ntau dua lossis sib npaug rau 27J ntawm 0℃(tus qauv)
Piv rauDH32/DH36, Qib Amuajqis zogtab sissuperior ductility, ua rau nws zoo tagnrho raucov txheej txheem thib obqhov twgweldability thiab formabilityyog qhov tseem ceeb.
3. Tshuaj muaj pes tsawg leeg
Cov pa roj carbon (C): Tsawg dua lossis sib npaug li 0.21%
Manganese (Mn): 0.60-1.60%
Silicon (Si): Tsawg dua lossis sib npaug li 0.35%
Phosphorus (P) thiab Sulfur (S): Tsawg dua lossis sib npaug li 0.035% txhua
Nwscov pa roj carbon tsawgua komzoo heev weldability, txo qhov kev pheej hmoo ntawm hydrogen -induced cracking.
4. Cov ntawv thov
Tsis yog- ntu tseem ceeb ntawm lub cev(piv txwv li, ballast tanks, bulkheads)
Deck plating(hauv qhov tsis yog-load-cov kabmob)
Offshore platforms thiab cov nkoj hauv av
5. Kev lag luam Standards & Certifications
CCS Cov Cai rau Cov Nkoj Hlau
GB/T 712-2011 (Suav teb chaws Standard)
ABS, DNV, LR (lwm daim ntawv pov thawj muaj)
6. Qhov zoo thiab qhov txwv
Pros:
Tus nqi- zoopiv rau siab -lub zog steels
Yooj yim fabrication(txiav, khoov, vuam)
Cons:
Tsis haum rau siab - qhov chaw muaj kev ntxhov siab(eg, hneev, stern)
Tsawg corrosion kuj(yuav tsum tau coatings tiv thaiv)
Xaus
CCS Qib Ayog antau yam, kev lag luam steelzoo tagnrho rautsis yog- cov qauv nkoj tseem ceeb. Thaum nws tsis muaj zog ntawmDH32/DH36,nwssuperior ductility thiab weldabilityua nws indispensable nyob rau hauvtus nqi -sensitive maritime tej yaam num. Tsim nyogkev tiv thaiv corrosionUa kom nws lub neej ntev nyob rau hauv ib puag ncig marine.
