LR EH46 steel phaj yog siab -lub zog, qis-kub qib shipbuilding steel ntawv pov thawj los ntawm Lloyd's Register (LR), paub txog zoo heev toughness, lub zog (Yield ~ 420 MPa, Tensile ~ 530-680 MPa), thiab zoo weldability, lub nkoj loj, feem ntau siv nyob rau hauv lub nkoj. hnyav, txias marine ib puag ncig. 'E' qhia txog nws qhov haum rau qhov kub thiab txias, 'H' qhia txog lub zog siab, thiab '46' qhia nws qhov tsawg kawg nkaus yield zog nyob rau hauv kg / mm², ua rau nws zoo tagnrho rau cov khoom siv tseem ceeb uas xav tau kev cuam tshuam.

Cov yam ntxwv tseem ceeb:
Txheem: LR (Lloyd's Register) Shipbuilding Steel Standard.
Lub zog: qib siab zog, muab kev ua tau zoo tshaj cov qib theem pib xws li LR Qib A lossis D.
Toughness: Zoo heev cuam tshuam toughness, txawm nyob rau hauv qis kub (piv txwv li, -40 degree), tseem ceeb heev rau marine kev nyab xeeb.
Daim ntaub ntawv: Nkoj hulls, offshore platforms, drilling rigs, yeeb nkab sib txuas, thiab lwm yam xav tau marine engineering tej yaam num.
Muaj pes tsawg leeg & Khoom: Ua tib zoo tswj chemistry (piv txwv li, Carbon tsawg, tshwj xeeb Silicon / Manganese) thiab kev kho cua sov kom ntseeg tau tias nws cov khoom siv, nrog qhov tsawg kawg nkaus elongation feem ntau nyob ib ncig ntawm 18%.
