GNEE STEEL yog tus muab khoom ntiag tug steel. Peb lub tuam txhab tau muab cov ntaub ntawv steel rau ntau xyoo, thiab ntau hom steel phaj hauv kev lag luam. Peb cov khoom siv hlau zoo yog siab, qhov zoo yog kev sib tw, thiab lub sijhawm sib pauv yog luv. Peb tsis tas yuav muab cov ntaub ntawv raw, peb tuaj yeem muab cov kev pabcuam ua haujlwm tsis tu ncua, thiab peb tuaj yeem muab cov neeg siv khoom nrog ntau hom kev ua haujlwm thiab cov duab sib txawv ntawm cov hlau.
EH36 steel yog lub zog muaj zog steel feem ntau siv hauv kev lag luam shipbuilding. Nov yog qee qhov tseem ceeb ntawm EH36 steel:

Daim ntawv thov:
EH36 steel feem ntau yog siv rau hauv kev tsim cov nkoj, nkoj, cov khoom siv hauv hiav txwv, cov qauv sab nrauv, thiab lwm yam kev siv tub rog uas yuav tsum tau muaj zog thiab zoo weldability.
Weldability:
EH36 steel muaj cov yam ntxwv zoo weldability, ua rau nws haum rau ntau yam txheej txheem vuam siv nyob rau hauv shipbuilding thiab marine kev tsim kho.
Ntawv pov thawj:
EH36 steel tuaj yeem raug lees paub los ntawm kev faib cov koom haum xws li ABS (American Bureau of Shipping) lossis DNV (Det Norske Veritas) kom ua tau raws li cov qauv kev lag luam tshwj xeeb thiab cov cai.
Impact Testing:
EH36 steel feem ntau dhau los ntawm kev ntsuas qhov ntsuas kub qis kom ntseeg tau tias nws lub zog thiab tsis kam ua rau tawg tawg nyob rau hauv qhov hnyav marine ib puag ncig.
Cov kev qhia tshwj xeeb no qhia txog qhov muaj pes tsawg leeg, cov khoom siv kho tshuab, kev siv, thiab cov qauv zoo uas cuam tshuam nrog EH36 steel, ib qho kev xaiv rau marine thiab naval structural daim ntaub ntawv uas yuav tsum tau muaj zog, durability, thiab weldability.
