ABS AH40 yog lub zog siab shipbuilding steel phaj, thiab ntawm no yog qhov sib txawv ntawm nws thiab lwm qib ntawm shipbuilding steel phaj:

 

Qib muaj zog:

Piv nrog rau lub zog dav dav nkoj tsim steel daim hlau (xws li A, B, D, E qib): Lub zog dav dav shipbuilding steel phaj muaj lub zog qis dua. Lawv qhov tsawg kawg nkaus tawm lub zog yog nyob ib ncig ntawm 235 MPa, thiab lub zog tensile nyob rau hauv thaj tsam ntawm 400-520 MPa. Hauv qhov sib piv, ABS AH40 muaj qhov siab tshaj qhov ua tau zoo ntawm tsis pub tsawg dua 390 MPa, thiab lub zog tensile yog nyob nruab nrab ntawm 510 thiab 660 MPa. Qhov no txhais tau hais tias AH40 tuaj yeem nqa tau ntau dua thiab tsim nyog rau cov ntawv thov uas yuav tsum muaj lub zog siab, xws li cov qauv tseem ceeb ntawm cov nkoj loj lossis cov qauv hauv ntug dej hiav txwv engineering2.

Piv nrog rau lwm cov khoom siv lub zog siab shipbuilding steel daim hlau (xws li DH40, EH40, FH40): Cov qib no yog tag nrho cov nyob rau hauv qeb ntawm high-strength shipbuilding steels, tab sis lawv muaj ntau yam kev ua tau zoo raws li tej yam toughness ntawm tsawg kub. Piv txwv li, qhov ntsuas kub ntawm DH40 yog -20 degree, EH40 yog -40 degree, thiab FH40 yog -60 degree . Thaum qhov ntsuas qhov ntsuas kub ntawm AH40 yog qhov siab dua (feem ntau nyob ib puag ncig 0 degree), uas txhais tau tias nws muaj kev cuam tshuam zoo dua ntawm qhov kub siab dua. Qhov no ua rau AH40 haum rau siv nyob rau hauv qhov chaw uas qhov kub thiab txias tsis tshua muaj siab 2.

Tshuaj muaj pes tsawg leeg: Txawm hais tias cov qib sib txawv ntawm shipbuilding steel phaj muaj cov ntsiab lus tseem ceeb xws li carbon (C), silicon (Si), manganese (Mn), phosphorus (P), thiab sulfur (S), cov ntsiab lus ntawm cov ntsiab lus no yuav txawv. Rau ABS AH40, nws muaj cov kev cai tshwj xeeb rau cov ntsiab lus ntawm cov ntsiab lus alloying thiab micro-alloying cov ntsiab lus xws li txhuas (Al), niobium (Nb), vanadium (V), thiab titanium (Ti) kom ntseeg tau tias nws lub zog thiab lwm yam ntsuas kev ua tau zoo. Cov tshuaj muaj pes tsawg leeg sib txawv kuj ua rau qhov sib txawv ntawm kev ua thiab vuam kev ua tau zoo ntawm cov qib sib txawv ntawm cov hlau phaj.

Daim ntawv thov scenarios:

Raws li kev xav tau ntawm lub zog: Vim nws lub zog siab, ABS AH40 tau siv dav hauv kev tsim cov nkoj loj, xws li cov qauv hull, lawj, thiab bulkheads ntawm cov nkoj loj, tankers, thiab cov nkoj ntim khoom. General zog shipbuilding steel daim hlau yog ntau haum rau tsawg xav tau qhov chaw los yog me me ships.

Raws li kev pabcuam ib puag ncig: Hauv thaj chaw uas muaj qhov kub thiab txias, ABS AH40 tuaj yeem ua tau raws li qhov xav tau zoo. Rau cov cheeb tsam uas tsis tshua muaj kub, xws li thaj tsam Arctic thiab Antarctic, qib zoo li EH40 thiab FH40 nrog rau qhov kub thiab txias tsis zoo cuam tshuam zoo dua los ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov qauv hauv cov cheeb tsam hnyav.

Cov txheej txheem tsim khoom thiab kev tswj xyuas zoo: Cov txheej txheem tsim khoom ntawm qib sib txawv ntawm cov nkoj tsim cov hlau phaj kuj tseem muaj qhov sib txawv. Rau cov qib siab zog zoo li ABS AH40, kev tswj cov txheej txheem nruj dua thiab kev tshuaj xyuas zoo yuav tsum tau ua thaum lub sijhawm tsim khoom los xyuas kom meej tias cov khoom siv kho tshuab thiab cov ntawv hlau ua tau raws li cov qauv. Qhov no suav nrog kev tswj qhov kub thiab txias, qhov cua txias, thiab cov txheej txheem kho cua sov, uas yog txhua yam tseem ceeb cuam tshuam rau kev ua haujlwm ntawm cov hlau phaj.
