Hauv ntiaj teb kev tsim nkoj thiab kev tsim kho hauv hiav txwv, kev xaiv cov phaj hlau yog qhov tseem ceeb rau kev ua kom muaj kev ruaj khov thiab kev ua haujlwm ntev. Ntawm cov hlau tsim nkoj uas siv ntau tshaj plaws yogABS AH36thiabLR DH36cov phaj. Kev nkag siab txog cov khoom siv kho tshuab ntawm cov ntaub ntawv no yog qhov tseem ceeb rau cov engineers thiab cov neeg tsim qauv kom txiav txim siab tau zoo. Tsab xov xwm no yuav muab kev sib piv ntawm ob qib hlau no, qhia txog lawv cov yam ntxwv tseem ceeb, kev siv, thiab qhov zoo.

Kev Txheeb Xyuas Txog ABS AH36 thiab LR DH36

ABS AH36yog qib hlau muaj zog siab uas tau pom zoo los ntawm American Bureau of Shipping (ABS). Nws siv dav hauv cov qauv dej hiav txwv thiab ntug dej hiav txwv vim nws qhov kev tawv thiab weldability zoo heev. AH36 phaj yog qhov tsim nyog tshwj xeeb rau cov ntawv thov uas xav tau qhov sib piv ntawm lub zog thiab qhov hnyav, xws li lub nkoj hulls thiab cov platforms ntug dej hiav txwv.

LR DH36, ntawm qhov tod tes, yog kev faib tawm los ntawm Lloyd's Register (LR). Nws tseem yog cov hlau ua nkoj muaj zog nrog cov khoom siv zoo heev, tsim nyog rau ntau yam kev siv hauv hiav txwv. DH36 tau txais kev nyiam rau nws qhov zoo sib xws thiab ua raws li cov qauv thoob ntiaj teb.

Ob hom hlau no yog tsim los kom tiv taus cov huab cua phem hauv dej hiav txwv, tab sis muaj qhov sib txawv me ntsis hauv lawv cov tshuaj lom neeg thiab kev ua haujlwm ntawm lub cev.

Kev Sib Txawv ntawm Cov Tshuaj Lom Zem

Txawm hais tias ob qho tib si ABS AH36 thiab LR DH36 yog cov hlau tsis muaj hlau ntau, lawv cov tshuaj sib xyaw ua ke sib txawv me ntsis, cuam tshuam rau lawv cov cwj pwm kho tshuab:

  • ABS AH36:Feem ntau muaj cov pa roj carbon, manganese, phosphorus, sulfur, thiab me ntsis ntawm nickel, chromium, thiab tooj liab. Cov pa roj carbon uas tswj tau ua kom muaj kev vuam zoo thiab tawv.

  • LR DH36:Muaj cov khoom zoo sib xws tab sis feem ntau muaj cov kev txwv sib txawv me ntsis rau cov pa roj carbon thiab manganese, uas tuaj yeem txhim kho kev tiv thaiv kev cuam tshuam hauv qhov kub qis.

Qhov sib txawv ntawm cov khoom sib xyaw, txawm hais tias me me xwb los, tseem ceeb thaum xaiv qib hlau rau cov ntawv thov tshwj xeeb, tshwj xeeb tshaj yog nyob rau hauv huab cua txias lossis cov chaw nyob hauv dej hiav txwv uas muaj kev ntxhov siab ntau.

Kev Sib Piv Txog Cov Khoom Siv Kho Tshuab

Cov khoom siv kho tshuab ntawm cov hlau phaj tsim nkoj yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ua tau zoo. Hauv qab no yog kev sib piv ntxaws ntawm ABS AH36 thiab LR DH36 phaj:

1. Lub zog tawm los

Lub zog tawm los qhia txog kev ntxhov siab uas cov khoom pib deform plastically.

  • ABS AH36:Lub zog tsawg kawg nkaus ntawm 355 MPa rau cov tuab txog li 50 hli.

  • LR DH36:Lub zog tsawg kawg nkaus ntawm 345 MPa rau cov tuab txog li 50 hli.

AH36 muaj zog dua me ntsis, ua rau nws tsim nyog dua rau cov ntawv thov uas xav tau kev tiv thaiv ntau dua rau kev hloov pauv hauv qab qhov hnyav.

2. Lub zog tensile

Lub zog tensile ntsuas qhov siab tshaj plaws ntawm kev ntxhov siab uas cov khoom siv tuaj yeem tiv taus thaum raug ncab.

  • ABS AH36:Lub zog tensile yog txij li 490 txog 620 MPa.

  • LR DH36:Lub zog tensile yog li ntawm 470 txog 630 MPa.

Ob qib muab kev ua tau zoo heev, tab sis AH36 muaj ntau yam sib xws dua rau kev kwv yees tus cwj pwm ntawm cov qauv.

3. Kev ntev

Kev nthuav dav ntsuas qhov ductility ntawm cov khoom, qhia tias nws tuaj yeem ncab ntau npaum li cas ua ntej tawg.

  • ABS AH36:Yam tsawg kawg nkaus elongation ntawm 21% rau tuab txog li 50 hli.

  • LR DH36:Yam tsawg kawg nkaus elongation ntawm 19% rau tuab txog li 50 hli.

Qhov ntev dua ntawm AH36 qhia tau tias nws muaj peev xwm nqus tau lub zog thaum lub sijhawm sib tsoo, ua rau nws ruaj khov dua.

4. Kev Cuam Tshuam Toughness

Kev ruaj khov ntawm qhov cuam tshuam yog qhov tseem ceeb rau cov ntaub ntawv siv rau hauv cov chaw txias hauv dej hiav txwv. Ob qho tib si AH36 thiab DH36 ua tau raws li cov kev cai nruj rau kev sim cuam tshuam hauv qhov kub qis, kom ntseeg tau tias cov hlau tuaj yeem tiv taus kev tawg yooj yim hauv qab cov xwm txheej hnyav.

5. Kev vuam tau

Ob qib hlau yog tsim los rau kev vuam zoo heev. AH36 phaj tuaj yeem vuam siv cov txheej txheem vuam ib txwm tsis tas yuav ua kom sov ua ntej rau cov seem nyias dua. DH36 kuj muaj cov yam ntxwv zoo sib xws tab sis yuav xav tau kev tswj cua sov rau cov seem tuab dua kom tiv thaiv kev tawg.
