Taw qhia rau Ss400 Steel

Qib txhais: Ss400 yog ib qib Japanese kev lag luam tus qauv rau cov qauv hlau. Lub "Ss" sawv cev rau "cov qauv hlau", thiab "400" sawv cev rau qhov tsawg kawg nkaus tawm lub zog ntawm cov hlau hauv megapascals (MPa). Nws yog ib qho uas feem ntau siv cov hlau me me vim nws qhov kev sib xyaw ua ke zoo ntawm cov khoom siv kho tshuab thiab cov nqi - kev ua tau zoo.

Tshuaj muaj pes tsawg leeg: Ss400 feem ntau muaj carbon (C), manganese (Mn), silicon (Si), sulfur (S), thiab phosphorus (P). Cov ntsiab lus carbon feem ntau yog nyob ib ncig ntawm 0.20% - 0.25%, uas muab lub zog yooj yim. Manganese pab ntxiv dag zog thiab txhim kho lub toughness ntawm cov hlau. Silicon ua tus deoxidizer thaum lub sij hawm steel - ua txheej txheem. Cov ntsiab lus ntawm sulfur thiab phosphorus yog khaws cia kom tsawg kom tsis txhob brittleness thiab lwm yam tsis zoo rau cov khoom siv kho tshuab.

Marine - qib thiab CCS chav kawm tseem ceeb

Marine - qib Requirements: Rau kev siv dej hiav txwv, cov hlau yuav tsum tau ua kom tau raws li cov kev cai tshwj xeeb ntsig txog kev tiv thaiv corrosion, lub zog, thiab toughness. Marine - qib Ss400 steel daim hlau feem ntau raug kho los yog alloyed los txhim kho lawv cov kev tiv thaiv rau seawater corrosion. Qhov no tuaj yeem koom nrog cov txheej txheem xws li txheej nrog cov tshuaj tiv thaiv corrosion los yog sib ntxiv ntawm qee yam alloying ntsiab.

CCS (China Classification Society) Kev faib tawm: CCS kev faib tawm qhia tias cov hlau phaj ua raws li cov qauv thiab cov kev cai tsim los ntawm CCS rau kev siv hauv cov qauv hauv hiav txwv. CCS muaj cov kev cai nruj heev txog kev ua tau zoo, kev tsim khoom, thiab kev ua haujlwm ntawm cov hlau siv hauv nkoj. Kev faib tawm los ntawm CCS muab kev lees paub tias cov hlau phaj yog tsim nyog rau lawv cov kev xav tau hauv hiav txwv thiab ua tau raws li kev nyab xeeb thiab kev ntseeg tau.

Mechanical Properties

 

Toughness: Ss400 steel kuj muaj qhov zoo toughness, uas yog ib qho tseem ceeb rau kev tiv thaiv tam sim ntawd cuam tshuam thiab dynamic loads nyob rau hauv marine ib puag ncig. Lub toughness tso cai rau cov hlau nqus lub zog thaum sib tsoo lossis cuam tshuam yam tsis muaj kev tawg. Hauv qhov xwm txheej uas lub nkoj yuav ntsib kev sib tsoo me me nrog cov khoom ntab, cov hlau tawv tawv tuaj yeem tiv thaiv kev puas tsuaj loj.

Ductility: Txaus ductility muaj nyob rau hauv Ss400 steel. Ductility tso cai rau cov hlau deform plastically rau qee qhov yam tsis muaj kev tawg. Cov cuab yeej no muaj txiaj ntsig zoo thaum lub sijhawm tsim khoom thaum cov hlau phaj yuav tsum tau khoov, zoo li, lossis tsim rau hauv cov qauv sib txawv. Nws kuj tseem pab cov hlau phaj hauv cov qauv marine kom hloov mus rau qee qhov kev deformation thaum lub nkoj ua haujlwm.

Kev siv hauv Marine Structures

Hull Kev Tsim Kho: Ss400 me me steel daim hlau yog dav siv nyob rau hauv kev tsim kho ntawm lub nkoj hulls. Lawv tuaj yeem siv rau hauv qab daim hlau, sab plhaub, thiab lwm qhov chaw ntawm lub cev. Lub zog thiab toughness ntawm cov hlau ua kom muaj kev ncaj ncees ntawm cov qauv hull kom tiv taus qhov hnyav marine ib puag ncig.

Deck thiab Bulkhead Installation: Rau decks thiab bulkheads, Ss400 steel muab lub zog tsim nyog los txhawb nqa qhov hnyav ntawm cov khoom siv, cov khoom thauj, thiab cov neeg coob. Cov hlau phaj tuaj yeem tsim rau hauv cov duab sib txawv thiab qhov ntau thiab tsawg kom tau raws li cov kev cai tshwj xeeb ntawm lub lawj thiab cov qauv tsim.

Sab hauv Cov Txheej Txheem Txheej Txheem: Ntxiv nrog rau lub ntsiab hull, lawj, thiab bulkhead, Ss400 steel kuj tseem siv rau cov khoom siv sab hauv xws li thav duab, stiffeners, thiab kev txhawb nqa. Cov khoom siv no pab txhawb nqa tag nrho cov qauv ntawm lub nkoj thiab faib cov khoom sib npaug.
