LR Shipbuilding Steel Phaj LR AH36, LR DH36, LR EH36, LR FH36 Marine Steel Phaj

LR (Lloyd's Register) shipbuilding steel phaj muaj cov yam ntxwv hauv qab no:

 

LR AH 36

 

Lub zog: Tus "H36" qhia qhov tsawg kawg nkaus tawm lub zog ntawm ib ncig ntawm 355 MPa. Lub zog no tso cai rau cov phaj hlau tuaj yeem tiv taus qhov kev ntxhov siab ntawm cov khoom siv thauj khoom thaum lub sijhawm ua haujlwm, xws li cov nthwv dej, cua, thiab cov khoom thauj.

Toughness: Nws muaj cov khoom zoo toughness, uas yog ib qho tseem ceeb rau kev tiv thaiv brittle fractures nyob rau hauv marine ib puag ncig. Qhov no ua kom muaj kev nyab xeeb thiab kav ntev ntawm lub nkoj cov qauv.

Daim ntawv thov: Feem ntau siv rau hauv kev tsim lub nkoj lub nkoj, decks, thiab lwm yam khoom siv.

 

LR DH 36

 

Txhim kho Toughness: Piv rau AH36, DH36 muaj qhov yuav tsum tau muaj zog dua, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias. Qhov no yog qhov tseem ceeb rau cov nkoj ua haujlwm hauv cov dej txias lossis hauv thaj chaw uas cov qauv yuav raug cuam tshuam rau qhov kub thiab txias.

Lub zog: Ua kom muaj zog zoo ib yam li AH36.

Kev siv: Feem ntau siv rau hauv cov cheeb tsam uas muaj kev pheej hmoo ntau dua los yog hauv cov nkoj uas ua haujlwm hauv thaj chaw txias dua.

 

LR EH 36

 

Siab zog thiab toughness: EH36 steel phaj muaj ob lub zog siab thiab zoo toughness. Lawv tau tsim los ua kom tau raws li qhov xav tau ntawm cov ntawv thov kev tsim kho nkoj tseem ceeb.

Tsawg - Kub Ua Haujlwm: Lawv kuj muaj kev ua tau zoo ntawm qhov kub thiab txias, ua kom muaj kev nyab xeeb thiab kev ncaj ncees ntawm lub nkoj cov qauv nyob rau hauv ntau yam ib puag ncig.

Cov cheeb tsam thov: Haum rau qhov tseem ceeb ntawm cov qauv ntawm cov nkoj uas xav tau kev sib xyaw ua ke ntawm lub zog siab thiab zoo-kub kub toughness.

 

LR FH36

 

Superior Toughness: FH36 muaj qhov yuav tsum tau muaj zog tshaj plaws ntawm cov qib no. Qhov no ua rau nws zoo tagnrho rau cov ntawv thov uas cov qauv raug cuam tshuam los ntawm kev cuam tshuam loj heev lossis hauv cov hlab ntsha tshwj xeeb uas xav tau qib siab tshaj plaws ntawm toughness thiab kev ntseeg tau.

Lub zog: Ua raws li lwm qib hauv cov ntsiab lus ntawm lub zog tawm los.

Kev siv: Feem ntau yog siv rau hauv cov cheeb tsam uas raug cuam tshuam los yog hauv cov hlab ntsha tshwj xeeb.
