Dh36 Eh36 High Strength Shipbuilding Alloy Steel Phaj

DH36 thiab EH36 high-strength shipbuilding alloy steel daim hlau yog cov ntaub ntawv tseem ceeb uas feem ntau siv nyob rau hauv shipbuilding thiab marine engineering. Nov yog cov lus qhia ntxaws ntxaws rau lawv:
Tshuaj muaj pes tsawg leeg:

 

DH 36: Nws cov tshuaj muaj pes tsawg leeg suav nrog cov ntsiab lus xws li carbon (C), manganese (Mn), silicon (Si), sulfur (S), thiab phosphorus (P). Cov ntsiab lus ntawm cov pa roj carbon monoxide yog tswj los ntawm qib qis kom ntseeg tau tias qhov toughness thiab vuam kev ua tau zoo ntawm cov phaj steel. Cov ntsiab lus tshwj xeeb yuav txawv me ntsis nyob ntawm cov chaw tsim khoom sib txawv thiab cov qauv kev cai, tab sis tag nrho, nws yog kom tau txais kev ua tau zoo.

EH 36: Hauv cov tshuaj muaj pes tsawg leeg, cov ntsiab lus carbon feem ntau tsis tshaj {{0}}.21%, cov ntsiab lus silicon tsis tshaj 0.55%, manganese cov ntsiab lus yog li 1.7%, thiab cov ntsiab lus ntawm sulfur thiab phosphorus. raug tswj nyob rau theem qis. Tsis tas li ntawd, qee qhov alloying xws li txhuas (Al), niobium (Nb), vanadium (V), thiab titanium (Ti) ntxiv. Qhov sib ntxiv ntawm cov ntsiab lus no tuaj yeem txhim kho lub zog, toughness, thiab corrosion kuj ntawm steel phaj.
Mechanical Properties:

DH 36: Lub zog tawm los tsis tsawg dua 355 MPa, lub zog tensile nyob nruab nrab ntawm 490-630 MPa, thiab elongation tsis tsawg dua 21%. Nws muaj qhov zoo plasticity thiab toughness thiab tuaj yeem tswj kev ua haujlwm ruaj khov hauv qhov chaw ua haujlwm hnyav. Nws tseem tuaj yeem tuav tau zoo toughness ntawm qhov kub thiab txias ntawm -20 degree .

EH 36: Lub zog tawm los yog siab dua 355 MPa, lub zog tensile nyob nruab nrab ntawm 490-620 MPa, thiab elongation tom qab tawg yog ntau dua lossis sib npaug li 21%. Nyob rau hauv ib puag ncig uas tsis kub, xws li -40 degree, nws qhov cuam tshuam nqus zog tuaj yeem ncav cuag qib siab. Nws muaj qhov zoo ntawm qhov kub thiab txias thiab yog qhov tsim nyog rau cov nkoj thiab cov qauv kev lag luam marine siv nyob rau hauv cov dej hiav txwv txias los yog ib puag ncig kub.

Qhov zoo thiab yam ntxwv:

Siab zog: Ob lub phaj hlau muaj lub zog muaj zog thiab tuaj yeem tiv taus cov khoom loj thiab cov kev cuam tshuam, ua tau raws li cov khoom siv zog ntawm cov nkoj thiab cov qauv kev lag luam marine.

Kev ua haujlwm vuam zoo: Nws yog qhov yooj yim rau shipyards los ua thiab tsim khoom. Nws tsis yog ib qho yooj yim kom muaj qhov tsis xws luag xws li cov kab nrib pleb thaum lub sij hawm vuam, thiab lub zog thiab tawv ntawm cov welded sib koom kuj tuaj yeem lav.

Corrosion kuj: Nws muaj kev tiv thaiv corrosion zoo nyob rau hauv ib puag ncig marine thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev, txo tus nqi kho thiab hloov.

Zoo toughness: Tshwj xeeb tshaj yog EH36 muaj qhov kub thiab txias toughness zoo thiab tsim nyog rau ntau qhov chaw hauv hiav txwv thiab kev ua haujlwm.
