Marine Steel Phaj LRA BDE

Marine Steel Phaj LRA B, D, thiab E yog cov qib sib txawv ntawm cov hlau phaj tsim los rau kev siv dej hiav txwv. Nov yog cov ntsiab lus ntawm cov qib no:

 

LRA B Qib:

 

Tshuaj muaj pes tsawg leeg: Feem ntau muaj cov pa roj carbon, manganese, silicon, sulfur, thiab phosphorus. Cov ntsiab lus carbon yog tswj xyuas kom muaj qhov sib npaug ntawm lub zog thiab ductility. Piv txwv li, nws yuav muaj cov ntsiab lus ntawm cov pa roj carbon monoxide nyob rau hauv ib qho chaw los muab lub zog nruab nrab yam tsis muaj kev txi ntau dhau weldability.

Mechanical Properties: Nws muaj qee qhov kev tawm dag zog, lub zog tensile, thiab elongation. Lub zog tawm los feem ntau yog nyob rau theem uas tuaj yeem tiv taus cov khoom nruab nrab. Piv txwv li, lub zog tawm los yuav nyob ib ncig ntawm tus nqi tshwj xeeb hauv MPa. Lub zog tensile ua kom lub phaj tuaj yeem tiv thaiv kev rub tawm. Elongation qhia lub peev xwm ntawm cov khoom kom deform ua ntej tawg.

Cov yam ntxwv thiab kev siv: Haum rau kev siv dej hiav txwv dav dav uas yuav tsum muaj lub zog nruab nrab thiab kav ntev. Yuav siv tau rau hauv kev tsim kho cov hlab ntsha me me los yog rau cov khoom siv hluav taws xob tsawg. Piv txwv li, nws tuaj yeem siv rau qee cov khoom siv sab hauv lossis thaj chaw uas cov khoom thauj tsis siab heev.

 

LRA D Qib:

 

Tshuaj muaj pes tsawg leeg: Tej zaum yuav muaj qhov sib txawv me ntsis piv rau qib LRA B, nrog kev hloov kho hauv cov ntsiab lus alloying. Piv txwv li, nws yuav muaj ntau dua manganese cov ntsiab lus los txhim kho lub zog thiab tawv.

Mechanical Properties: Qhia tawm lub zog ntau dua thiab lub zog tensile tshaj LRA B qib. Qhov no ua rau nws haum rau cov ntawv thov uas xav tau lub zog ntau dua. Lub elongation kuj tseem tuaj yeem ua kom zoo kom ntseeg tau qee qhov kev sib tw.

Cov yam ntxwv thiab kev siv: Siv nyob rau hauv qhov xav tau ntau dua marine ib puag ncig lossis rau cov nkoj loj dua qhov xav tau cov ntaub ntawv muaj zog dua. Nws tuaj yeem ua haujlwm rau cov qauv hull, decks, thiab lwm qhov chaw uas yuav tsum tau tiv taus kev ntxhov siab ntau dua thiab thauj khoom. Piv txwv li, ntawm cov nkoj loj thauj khoom lossis cov chaw tawm ntug dej hiav txwv.

LRA E Grade:

 

Tshuaj muaj pes tsawg leeg: Feem ntau muaj cov khoom ua kom zoo nrog cov khoom siv tshwj xeeb los txhim kho qee yam khoom. Piv txwv li, nws yuav muaj cov khoom uas txhim khu kev tiv thaiv corrosion los yog kub-kub toughness.

Mechanical Properties: Nws muaj lub zog tensile siab heev. Tsis tas li ntawd, nws tuaj yeem muaj qhov ua tau zoo ntawm qhov kub thiab txias tsis kam. Qhov no ua rau nws haum rau cov ntawv thov nyob rau hauv qhov hnyav marine ib puag ncig lossis hauv thaj chaw uas muaj xwm txheej huab cua.

Cov yam ntxwv thiab kev siv: Zoo tagnrho rau cov txheej txheem marine tseem ceeb xws li cov haujlwm hauv thaj chaw txias lossis rau cov nkoj tshwj xeeb. Piv txwv li, nws tuaj yeem siv rau cov dej khov lossis cov nkoj ua haujlwm hauv cov xwm txheej hauv Arctic. Nws muab txhim khu kev ntseeg tau thiab durability nyob rau hauv ib puag ncig nyuaj.
