Ntawm cov ntau hom muaj,hlau marine muaj zog heevthiablub zog ib txwm muaj marine steelyog ob pawg uas siv ntau. Kev nkag siab txog qhov sib txawv ntawm lawv yog qhov tseem ceeb rau cov neeg ua nkoj, cov neeg tsim qauv, thiab cov kws ua haujlwm kom txiav txim siab tau zoo. Tsab xov xwm no tshawb nrhiav cov khoom siv kho tshuab, kev siv, qhov zoo, thiab kev txiav txim siab rau kev xaiv cov hlau marine zoo.

Txheej txheem cej luam ntawm Marine Steel

Cov hlau marine yog tsim tshwj xeeb los tiv taus cov xwm txheej hnyav ntawm cov chaw marine, suav nrog kev xeb dej ntsev, cov khoom hnyav, thiab qhov kub qis. Nws yuav tsum muaj lub zog txaus, kev tawv, thiab kev vuam tau zoo rau kev tsim cov nkoj, cov platforms offshore, thiab lwm yam qauv marine.

  • Cov Hlau Marine Muaj Zog Ib Txwm Muaj:Hom no feem ntau hu ua hlau tsis hnyav lossis hlau txheem rau kev tsim kho nkoj. Nws tsim nyog rau kev siv dav dav uas xav tau cov khoom hnyav nruab nrab thiab cov xwm txheej ib puag ncig.

  • Cov Hlau Marine Muaj Zog Siab:Raws li lub npe qhia, cov hlau muaj zog muaj cov khoom siv kho tshuab zoo dua, suav nrog cov txiaj ntsig siab dua thiab lub zog tensile, txhim kho kev tawv, thiab kev ua tau zoo dua hauv cov xwm txheej hnyav.

Txawm hais tias ob hom hlau ua haujlwm rau kev siv hauv hiav txwv, lawv cov yam ntxwv ua tau zoo sib txawv heev, ua rau kev xaiv kom raug yog qhov tseem ceeb.

Kev Sib Piv Txog Cov Khoom Siv Kho Tshuab

Qhov sib txawv tseem ceeb ntawm cov hlau marine muaj zog thiab cov hlau marine muaj zog ib txwm yog nyob rau hauv lawv cov khoom siv kho tshuab, uas cuam tshuam ncaj qha rau kev ua tau zoo hauv cov chaw ib puag ncig marine.

1. Lub zog tawm los

Lub zog tawm los yog qhov kev ntxhov siab uas cov hlau pib deform plastically.

  • Cov Hlau Muaj Zog Ib Txwm:Feem ntau muaj lub zog tso zis ntawm kwv yees li 235-275 MPa. Qhov no txaus rau cov ntawv thov thauj khoom nruab nrab tab sis tuaj yeem hloov pauv thaum muaj kev ntxhov siab hnyav.
