NK DH 32 36 40 Marine Steel Phaj

"NK DH32/36/40 Marine Steel Phaj" yog hais txog cov nkoj tsim cov hlau daim hlau uas tau lees paub los ntawm Nippon Kaiji Kyokai (ClassNK), uas muaj npe nrov hauv zej zog.

 

Cov hlau phaj no muaj cov yam ntxwv thiab cov khoom nram qab no:

 

Yam ntxwv:

 

Lub zog siab: Cov qib DH32, DH36, thiab DH40 muab cov qib zog ntxiv. Lawv tuaj yeem nqa cov khoom hnyav thiab kev ntxhov siab, ua kom muaj kev ncaj ncees ntawm cov nkoj thiab cov qauv hauv hiav txwv.

Zoo toughness: Muaj zoo toughness, tshwj xeeb tshaj yog nyob rau hauv qis kub. Qhov no ua rau lawv tuaj yeem tiv taus qhov cuam tshuam thiab muaj zog muaj zog uas tau ntsib nyob rau hauv ib puag ncig marine yam tsis tau tawg yooj yim.

Weldability: tuaj yeem welded siv cov txheej txheem vuam tsim nyog thiab cov txheej txheem. Txawm li cas los xij, vim lawv lub zog siab thiab cov ntsiab lus alloy, yuav tsum tau ua tib zoo saib xyuas cov txheej txheem vuam kom ntseeg tau zoo welds.

Corrosion resistance: Muaj qee qhov kev tiv thaiv corrosion los ntawm seawater thiab marine atmospheres. Cov txheej tiv thaiv ntxiv tuaj yeem siv rau kev tiv thaiv corrosion zoo dua.

Quenching	Tsis siv rau ib txwm siv. Feem ntau, AH36 marine steel phaj tsis quenched.

 

Cov khoom:

 

Cov tshuaj muaj pes tsawg leeg: Nws txawv nyob ntawm qib tab sis feem ntau muaj cov ntsiab lus xws li carbon, silicon, manganese, phosphorus, sulfur, thiab ntau yam alloying ntsiab kom ua tiav cov khoom xav tau.

Mechanical zog:

Yield zog: DH32 feem ntau muaj lub zog tawm los ntawm ib puag ncig 315 MPa, DH36 muaj lub zog tawm los ntau dua li ntawm 355 MPa, thiab DH40 muaj lub zog tawm los ntau dua.

Lub zog tensile: Ntau yam ntawm kwv yees li 440 MPa rau DH32 mus rau qhov siab dua rau DH36 thiab DH40.

Elongation: Feem ntau nyob ib ncig ntawm 22% lossis ntau dua, qhia txog lub peev xwm ntawm cov hlau kom deform tsis tawg.

 

Cov paib marine steel no tau siv dav hauv kev lag luam shipbuilding rau kev tsim cov hulls, decks, bulkheads, thiab lwm yam qauv ntawm cov nkoj. Lawv kuj tau ua haujlwm nyob rau hauv cov qauv ntawm ntug dej hiav txwv thiab cov haujlwm ua haujlwm hauv hiav txwv uas yuav tsum tau muaj zog thiab ua haujlwm ntev. Qhov kev xaiv ntawm ib qib tshwj xeeb yog nyob ntawm tus qauv tsim, kev ua haujlwm, thiab lub peev xwm thauj khoom ntawm daim ntawv thov npaj.
