Qib D Shipbuilding Hlau Phaj|ABS Qib D Marine Steel Supplier

Qib D shipbuilding steel phajyog ib qho dav dav -lub zog, siab -cov qauv steel ntawv pov thawj raws liASTM A131/A131Mlos ntawm txhua lub koom haum loj (ABS, BV, CCS, LR, DNV, thiab lwm yam). Nws yog tsim tshwj xeeb rau kev tsim cov nkoj hulls, offshore platforms, thiab cov khoom siv hauv hiav txwv uas yuav tsum muaj kev tswj xyuas kev ncaj ncees nyob rau hauv ib puag ncig qhov kub thiab txias.-20 degree.

Los ntawm kev muab qhov zoo tshaj plaws ntawm qhov sib npaug ntawm lub zog, weldability, thiab qis- qhov kub thiab txias, Qib D muab cov neeg tsim nkoj nrog kev ntseeg siab, tus nqi- siv tau zoo rau dej hiav txwv- cov nkoj mus, tshwj xeeb tshaj yog cov kev taug kev siab - latitude lossis caij ntuj no.

Vim li cas Qib D? Qhov qis-Qhov Kub Zoo Tshaj

Lub defining yam ntxwv ntawmQib D steel phajyog nws zoo heev cuam tshuam toughness ntawm-20 degree. Qhov no distinguishes nws tseem ceeb ntawm cov qib qis

Charpy V-Ntch Impact Test:Ua ntawm-20 degree(piv rau 0℃rau Qib B, thiab tsis tas yuav tsum muaj rau qib A). Qhov no ua kom muaj kev ncaj ncees hauv cov dej khov thiab siab - txoj kab latitude.

Siab zog:Yam tsawg kawg yield zog ntawm235 MPa rauthiab tensile zog ntawm400-520 MPa, sib piv lub zog ntawm Qib A, B, thiab E.

Grade D shipbuilding steel plate in stock

Fine Grain xyaum:Tsim los siv cov kev coj ua zoo (feem ntau nrog Aluminium, Als Ntau dua lossis sib npaug li 0.015%) los txhim kho cov khoom siv kho tshuab.

Weldability:Tsawg carbon sib npaug (CEV) ua kom muaj kev sib txuas zoo heev, tseem ceeb heev rau kev loj - nplai shipbuilding.

FAQ

01.Dab tsi yog qhov txawv ntawm Qib D thiab Qib B shipbuilding steel?

Qhov sib txawv tseem ceeb nyob hauv qhov ntsuas qhov ntsuas kub. Qib B raug kuaj ntawm 0 degree, thaum Qib D raug kuaj ntawm -20℃. Ob leeg muaj tib lub zog tawm los (235 MPa) thiab lub zog tensile (400-520 MPa). Yog tias koj lub nkoj yuav mus rau thaj chaw dej txias uas qhov kub tuaj yeem poob qis dua, Qib D yog qhov kev xaiv zoo dua thiab txhim khu kev qha. Qib B feem ntau txaus rau cov ntug hiav txwv dej lossis hauv av nrog cov huab cua me me.

02.Puas Qib D steel phaj siv sib hloov nrog Qib A?

Tsis yog, tsis yog tias qhov kub tsawg -kub toughness yuav tsum tau los ntawm koj tus qauv tsim lossis kev faib tawm. Qib A uatsis yogyuav tsum muaj Charpy V-qhov ntsuas qhov ntsuas qhov ntsuas (rau cov thicknesses tsawg dua los yog sib npaug li 50mm), hos Qib D qhov kev ua tau zoo raug txheeb xyuas ntawm -20℃. Thaum Qib D feem ntau tuaj yeem hloov Qib A raws li kev hloov kho tshiab, kev hloov pauv rov qab tsis tso cai yam tsis muaj kev rov ua dua tshiab.

03.Dab tsi thicknesses thiab tus me nyuam tej yam kev mob koj muab rau Qib D daim hlau?

Peb muab Grade D daim hlau nyob rau hauv thicknesses xws li 4mm mus rau 400mm, nrog widths mus txog 4000mm. Kev xa khoom muaj xws li As-rolled (AR), Tswj Rolling (CR), Normalized (N), thiab TMCP. Rau cov phaj tuab (feem ntau> 50mm) los yog xav tau daim ntawv thov, peb pom zoo kom Normalized los yog TMCP los xyuas kom meej cov qauv zoo dua thiab zoo dua toughness. Thov qhia koj cov thickness thiab cov xwm txheej uas yuav tsum tau thaum thov kev tsocai.

04.Koj puas muab daim ntawv pov thawj zeb thiab thib peb -kev tshuaj xyuas?

Yog lawm, kiag li. Txhua qhov khoom xa tuaj tuaj nrog Daim Ntawv Pov Thawj Zeb Xeem (EN 10204 Hom 3.1 lossis 3.2) tau lees paub los ntawm cov khoom tsim. Peb kuj txhawb nqa thib peb- kev tshuaj xyuas los ntawm cov koom haum kev faib tawm xws li ABS, BV, LR, DNV, CCS, thiab cov koom haum ywj pheej xws li SGS lossis TÜV raws li kev thov. Cov kev xeem ntxiv (piv txwv li, Ultrasonic Examination, Z- kev ntsuas kev taw qhia) tuaj yeem npaj kom tau raws li koj qhov project specifications. Peb xyuas kom meej tag nrho traceability los ntawm tshav kub tooj mus rau zaum kawg tus me nyuam.
