BV E460 Hlau Daim Hlau yog tus hwm zoo cov khoom lag luam shrbuilding tsim los ua kom tau raws li cov txheej txheem phom sij ntawm kev lag luam ntawm marine. Cov qhab nia ntawm cov hlau ua kom pom lub zog zoo tshaj plaws, ua kom muaj zog, ua rau lawv siv cov khoom siv uas xav tau qib siab thiab kev nyab xeeb.
Nyob rau hauv cov nqe lus ntawm cov tshuaj muaj kuab lom, bv e460 hlau daim hlau tau ua tib zoo ua kom muaj cov ntsiab lus zoo sib xws. Lawv feem ntau muaj cov pa roj carbon, silicon, mangholorus, sulfur, chromium, thiab npib chromenum, thiab npib tsib xee nyob rau hauv cov profortirts kom ua tiav cov khoom siv yam xav tau. Cov tshuaj lom nchuav ua kom muaj kev tiv thaiv zoo heev rau kev xeb thiab qaug zog, tseem ceeb heev rau nrog rau lub nkoj marine hnyav.

Hais txog qhov loj me, cov phiaj hlau no muaj nyob rau hauv ntau thicknesses, dav, thiab ntev kom haum rau ntau yam khoom siv shipbuilding. Lawv qhov yooj yim ntawm qhov loj me tso cai rau kev siv cov khoom siv tau zoo thiab txo qhov xav tau kev txiav tawm ntau dhau los lossis vuam thaum tsim kho.
Kev Cuam Tshuam yog ib qho tseem ceeb ntawm kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm BV E460 hlau daim hlau. Cov kev ntsuam xyuas no tau ua nyob rau ntawm qis kub los ntsuas cov khoom siv tiv thaiv mus rau brittle baciture. Cov phiaj hlau hlau yuav tsum ua tiav cov kev cuam tshuam nruj me ntsis kom ntseeg tau tias lawv muaj peev xwm tiv taus ntau yam tsis muaj kev poob siab.
Thawj cov ntawv thov rau BV E460 hlau daim hlau nyob hauv kev tsim kho cov nkoj thiab lwm yam nkoj marine. Cov phiaj no feem ntau siv nyob rau hauv Hull cov qauv, decks, bulkheads, thiab lwm yam tseem ceeb uas yuav tsum muaj zog thiab kav ntev. Lawv cov vuam zoo nkauj tua kuj ua rau lawv haum rau fabricating cov txheej txheem nyuaj thiab pob qij txha.
