ABS Shipbuilding Steel Phaj Qib AH32 DH32 AH36 EH36 AH40 Nrog ABS Ntawv Pov Thawj

ABS Shipbuilding Steel Phaj Qib AH32, DH32, AH36, EH36, thiab AH40 nrog ABS Daim Ntawv Pov Thawj yog cov ntawv hlau zoo siv dav hauv kev lag luam shipbuilding. Nov yog lawv cov yam ntxwv tseem ceeb thiab kev siv:

 

Chemical Composition thiab Mechanical Properties:

AH32 thiab DH32: Cov qib no muaj lub zog muaj zog thiab zoo ductility. Cov ntsiab lus ntawm cov pa roj carbon monoxide yog tswj hwm kom ntseeg tau lub zog ntawm cov hlau, thaum cov hlau alloying xws li manganese tau ntxiv los txhim kho cov khoom siv kho tshuab. Piv txwv li, cov ntsiab lus carbon feem ntau yog nyob rau hauv ib qho chaw, thiab cov ntsiab lus manganese nyob ib ncig ntawm tus nqi tshwj xeeb kom ua tiav qhov xav tau lub zog thiab toughness. Lub zog tawm los ntawm AH32 thiab DH32 feem ntau yog siab dua ib qib (piv txwv li, nyob ib ncig ntawm 315 MPa rau AH32 thiab 325 MPa rau DH32), thiab lub zog tensile kuj nyob rau hauv ib qho tshwj xeeb kom tau raws li qhov yuav tsum tau muaj ntawm lub nkoj tsim lub zog.

AH36 thiab DH36: Lawv muaj zog dua AH32 thiab DH32. Cov tshuaj muaj pes tsawg leeg yog hloov kho kom tau txais cov cuab yeej zoo dua qub. Cov ntsiab lus alloying tau ntxiv rau hauv qhov tsim nyog kom ntseeg tau tias cov hlau muaj lub zog muaj zog (feem ntau siab dua 355 MPa) thiab lub zog tensile (nyob ib ncig ntawm 490 - 630 MPa), uas yog tsim rau kev tsim kho ntawm qhov tseem ceeb ntawm cov nkoj uas xav tau siab. zog.

EH 36: Qib no muaj ntau dua lub zog thiab toughness yuav tsum tau, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm kev cuam tshuam los ntawm qhov kub thiab txias. Nws yog tsim rau siv nyob rau hauv hnyav marine ib puag ncig thiab rau kev tsim kho ntawm cov qauv tseem ceeb uas yuav tsum tau tiv taus siab loads thiab mob hnyav.

AW 40: Nws yog cov hlau phaj siab uas muaj lub zog siab tshaj plaws ntawm cov qib no. Nws muaj cov cuab yeej zoo heev thiab feem ntau yog siv rau kev tsim kho tshwj xeeb ntawm cov nkoj uas xav tau lub zog siab heev, xws li hneev nti thiab stern qauv ntawm cov nkoj loj.

Qhov sib txawv tseem ceeb ntawm DNV (Det Norske Veritas) steel phaj AH36 thiab lwm qib yog raws li hauv qab no:

 

Mechanical Properties

 

Lub zog

Yield zog: AH36 muaj qhov tsawg kawg nkaus tawm lub zog ntawm 355 MPa. Piv nrog rau qis-qib steels zoo li A36 (yield zog nyob ib ncig ntawm 250 MPa), AH36 tuaj yeem tiv taus ntau dua ua ntej deformation mus tas li. Qhov no ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum muaj kev ncaj ncees ntau dua, xws li hauv cov nkoj loj lossis cov qauv hauv ntug dej hiav txwv.

Tensile zog: Lub zog tensile ntawm AH36 feem ntau yog nyob ntawm 490 - 630 MPa. Hauv qhov sib piv, qee cov qib steel me me tuaj yeem muaj lub zog tensile nyob rau hauv thaj tsam ntawm 370 - 500 MPa. Lub zog tensile siab dua ntawm AH36 tso cai rau nws los tiv thaiv raug rub tawm hauv qhov nro.

Toughness

AH36 muaj qhov zoo toughness, tshwj xeeb tshaj yog nyob rau hauv qis kub. Qhov no yog qhov tseem ceeb rau kev siv hauv qhov chaw txias lossis hauv cov qauv uas yuav raug cuam tshuam rau kev thauj khoom. Piv txwv li, nyob rau hauv Arctic shipping los yog offshore ua hauj lwm, AH36 lub peev xwm los tswj nws txoj kev ncaj ncees nyob rau hauv qis - kub tej yam kev mob yog ib tug txawv zoo dua lwm yam qib uas tej zaum yuav nkig.

 

Tshuaj muaj pes tsawg leeg

 

Carbon thiab Alloying Elements

Cov ntsiab lus carbon hauv AH36 feem ntau yog nyob ib puag ncig 0.18% lossis tsawg dua. Qhov no yog ua tib zoo tswj kom sib npaug zog thiab lwm yam khoom. Nrog rau cov pa roj carbon, qhov muaj thiab feem ntawm cov khoom alloying xws li manganese (feem ntau nyob ib ncig ntawm 0.9 - 1.6%), silicon, thiab lwm yam raug kho. Piv rau qee cov pa roj carbon steel, qhov tshwj xeeb ua ke ntawm cov ntsiab lus hauv AH36 muab nws cov khoom siv kho kom zoo. Piv txwv li, cov ntsiab lus ntau dua manganese pab txhawb rau nws lub zog thiab toughness.

Qib impurity

Cov theem ntawm impurities zoo li phosphorus thiab sulfur yog khaws cia qis hauv AH36. Cov ntsiab lus phosphorus feem ntau txwv kom tsawg dua 0.035% thiab sulfur tsawg dua 0.035%. Qhov no yog ib qho tseem ceeb vim hais tias qib siab ntawm cov impurities tuaj yeem ua rau brittleness thiab txo weldability. Hauv qee qhov qis - cov hlau tsis zoo, cov qib impurity yuav siab dua, uas tuaj yeem cuam tshuam tsis zoo rau kev ua haujlwm ntawm cov khoom.

 

Weldability

 

Compatibility nrog Vuam txheej txheem

AH36 yog tsim los ua kom muaj kev sib txuas zoo siv cov txheej txheem vuam xws li arc vuam thiab roj-shielded vuam. Lub tshav kub - cuam tshuam cheeb tsam thaum vuam tswj tau cov khoom siv tau zoo. Qhov no yog qhov sib piv rau qee qhov siab-lub zog steels uas yuav xav tau cov txheej txheem vuam tshwj xeeb lossis ua ntej thiab tom qab vuam kev kho cua sov. Qhov zoo weldability ntawm AH36 ua kom yooj yim rau kev tsim kho thiab ua kom muaj kev ncaj ncees ntawm cov pob qij txha hauv nkoj tsim thiab lwm yam kev siv.

Weld Zoo

Cov welded pob qij txha ua nrog AH36 steel daim hlau feem ntau muaj lub zog zoo thiab ductility. Qhov no yog vim cov tshuaj muaj pes tsawg leeg thiab microstructure ntawm AH36 yog qhov tsim nyog rau kev tsim cov welds muaj zog thiab txhim khu kev qha. Hauv kev sib piv, qee qhov lwm qib yuav tsim cov welds nrog qis qis, xws li qhov muaj feem ntau ntawm cov porosity lossis tawg.

 

 

 

DNV steel phaj AH36 muaj cov kev siv hauv qab no:

 

Hauv Marine Kev Lag Luam

 

Shipbuilding

Hull Kev Tsim Kho: Nws yog dav siv hauv kev tsim cov nkoj hulls. Lub hull yog lub cev tseem ceeb ntawm lub nkoj uas yuav tsum tau tiv taus ntau lub zog xws li dej siab, nthwv dej, thiab qhov hnyav ntawm lub nkoj nws tus kheej. AH36 steel phaj muab qhov tsim nyog lub zog thiab kav ntev. Piv txwv li, nyob rau hauv kev tsim kho ntawm cov nkoj loj thauj khoom lossis cov tsheb thauj khoom, cov phaj hull feem ntau yog ua los ntawm AH36 los xyuas kom meej cov qauv ntawm lub nkoj thaum lub sij hawm ntev voyages thiab nyob rau hauv txawv hiav txwv tej yam kev mob.

Deck thiab Bulkhead Construction: Decks yog siv rau kev thauj khoom thiab tshem tawm cov khoom thauj thiab rau kev txav ntawm cov neeg coob coob. AH36 steel yog siv los tsim cov decks uas tuaj yeem nqa cov khoom hnyav. Bulkheads faib lub sab hauv ntawm lub nkoj mus rau hauv compartments. Lawv yog tsim los ntawm AH36 steel los muab kev ruaj ntseg thiab kev nyab xeeb los ntawm kev tiv thaiv kev sib kis ntawm cov dej nyob rau hauv rooj plaub ntawm kev ua txhaum ntawm lub nkoj.

Offshore Structures

Offshore Platforms: Offshore roj thiab roj platforms raug rau qhov hnyav marine ib puag ncig. AH36 steel phaj yog siv rau hauv kev tsim kho ntawm lub platform cov khoom siv xws li lub tsho thiab lub lawj. Lub tsho txhawb nqa lub platform saum npoo dej thiab yuav tsum tau tiv taus cua, nthwv dej, thiab dej ntws. AH36 steel muab qhov yuav tsum tau muaj zog thiab toughness rau daim ntawv thov no.

Subsea Pipelines: Txawm hais tias siab dua - qib steel feem ntau yog siv rau qhov tseem ceeb ntawm cov kav dej hauv qab dej, AH36 steel phaj tuaj yeem siv rau qee qhov tsis tseem ceeb lossis rau cov qauv kev txhawb nqa. Cov kav dej no thauj cov roj, roj, lossis lwm yam dej los ntawm hiav txwv mus rau saum npoo.

 

Hauv Lwm Cov Hnyav - Cov Qauv Ua Haujlwm

 

Kev tsim kho choj

Hauv kev tsim cov choj, tshwj xeeb tshaj yog nyob rau hauv cov ntug hiav txwv dej lossis hla dej, AH36 steel phaj tuaj yeem siv tau. Cov hlau lub zog thiab corrosion kuj ua rau nws haum rau cov khoom siv choj xws li girders thiab piers. Cov khoom no yuav tsum tiv taus qhov hnyav ntawm tus choj lawj, tsheb thauj mus los, thiab cov teebmeem corrosive ntawm ib puag ncig ib puag ncig.

Khoom siv

AH36 steel tuaj yeem siv rau hauv kev tsim cov khoom siv hnyav xws li cranes, mining machinery, thiab cov hlab ntsha siab. Piv txwv li, nyob rau hauv kev tsim kho ntawm ib tug loj crane, lub boom thiab lwm yam structural qhov chaw yuav ua los ntawm AH36 steel los xyuas kom meej tias lub crane tuaj yeem nqa hnyav hnyav.
