Qhov yuav tsum tau muaj rau lwm yam khoom ntawm GL Nkoj Hlau Phaj hauv Shipbuilding Codes thoob plaws ntau lub tebchaws thiab cheeb tsam

Lub ntiaj teb ntawm kev tsim khoom nkoj tau tswj hwm kom muaj kev nyab xeeb, ruaj khov, thiab kev ua haujlwm ntawm cov nkoj. Ntau lub teb chaws thiab cheeb tsam muaj cov kev cai tshwj xeeb rau ntau yam khoom ntawm GL Nkoj Hlau Phaj tshaj li cov lus sib tham.

Ib qho tseem ceeb yog lub zog tensile. Qee lub tebchaws tuaj yeem tsim lub zog tensile yam tsawg kawg nkaus rau GL Ship Steel Phaj los lav nws lub peev xwm los tiv thaiv lub zog ntawm lub nkoj cov qauv. Piv txwv li, hauv qee lub tebchaws nyob sab Europe, lub zog tensile yam tsawg kawg nkaus tuaj yeem raug teeb tsa ntawm 490 MPa, thaum nyob hauv cov tebchaws Esxias xws li Kaus Lim Qab Teb, nws yuav siab dua me ntsis ntawm 510 MPa.

Impact toughness yog lwm yam khoom tseem ceeb. Cov cheeb tsam sib txawv muaj qhov sib txawv raws li lawv cov kev mob ib puag ncig thiab kev npaj siv cov nkoj. Hauv cov cheeb tsam uas muaj huab cua txias los yog qhov chaw cov hlab ntsha ua haujlwm nyob rau hauv qhov xwm txheej hnyav, yuav raug yuam kom muaj kev cuam tshuam ntau dua. Piv txwv li, nyob rau hauv Nordic lub teb chaws, qhov cuam tshuam lub zog nqus ntawm qhov kub thiab txias rau GL Ship Steel Phaj yuav tsum tau ua kom siab dua piv rau cov cheeb tsam sov.

Kev tiv thaiv corrosion yog qhov tseem ceeb tshaj plaws, tshwj xeeb tshaj yog rau cov nkoj ua haujlwm hauv dej ntsev. Qee lub teb chaws yuav muaj cov qauv nruj rau kev muaj pes tsawg leeg thiab kev kho saum npoo ntawm cov phaj steel los txhim kho nws cov kev tiv thaiv corrosion. Qhov no tuaj yeem suav nrog kev txwv tshwj xeeb ntawm cov ntsiab lus ntawm cov ntsiab lus xws li chromium thiab npib tsib xee, lossis cov cai rau cov txheej txheem tiv thaiv.

Weldability kuj yog qhov tseem ceeb rau kev txiav txim siab. Cov lej sib txawv ntawm kev tsim cov nkoj tuaj yeem sau cov txheej txheem tshwj xeeb thiab cov kev txwv rau vuam GL Nkoj Hlau Phaj kom ntseeg tau cov pob qij txha muaj zog thiab txhim khu kev qha. Qee qhov chaw yuav tsom mus rau cov khoom siv hluav taws xob thaum lub sij hawm vuam, thaum lwm tus yuav hais txog kev kho cua sov ua ntej thiab tom qab vuam.
