Feem ntau, cov pa roj carbon sib npaug Ce yuav tsum ua kom tau raws li qhov yuav tsum tau ua hauv qab no: feem ntau, Ce Tsawg dua lossis sib npaug rau {{0}}.40%; Yog tias qhov kev xa khoom yog TMPC, thaum lub thickness tsawg dua lossis sib npaug li 50 hli, Ce Tsawg dua lossis sib npaug rau 0.36%, thiab thaum lub thickness yog> 50 - 100 hli, Ce Tsawg dua lossis sib npaug li 0.38% (Carbon sib npaug Ceq%=(C + Mn) / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15).

III. Mechanical Properties

1. Yield zog Re (MPa): Ntau dua lossis sib npaug rau 315
2. Tensile zog Rm (MPa): 440 - 570
3. Elongation A (%): Ntau dua lossis sib npaug 22
4. Longitudinal impact zog Akv / J: Qhov cuam tshuam lub zog yuav tsum tau nyob rau hauv qhov ntsuas kub sib txawv thiab steel phaj thicknesses yog raws li nram no:
- Ntawm 0 degree , thaum lub thickness tsawg dua los yog sib npaug li 50 hli, qhov ntev ntawm qhov cuam tshuam lub zog yog ntau dua los yog sib npaug rau 31J.
- Ntawm 0 degree , thaum 50mm < thickness Tsawg dua los yog sib npaug rau 70mm, qhov ntev ntawm qhov cuam tshuam lub zog loj dua los yog sib npaug rau 38J.
- Ntawm 0 degree , thaum 70mm < thickness Tsawg dua los yog sib npaug rau 100mm, qhov kev cuam tshuam ntev zog yog ntau dua lossis sib npaug rau 46J.

IV. Specifications

Thickness: 4mm txog 260mm

Dav: 1200mm txog 4000mm

Ntev: 3000mm txog 18000mm

V. Kev xa khoom

Kev xa khoom ntawm AH32 steel daim hlau suav nrog cov khoom zoo lis pawg thiab cov hlau ntawm cov thicknesses sib txawv, tshwj xeeb hauv qab no:

- Thaum lub thickness tsawg dua los yog sib npaug rau 12 hli, A (arbitrary), N (normalizing), CR (tswj dov), TM (TMPC, kub-deformation tswj dov) tuaj yeem txais yuav.
- Thaum lub thickness nyob nruab nrab ntawm 12.5 - 20mm, N (normalizing), CR (tswj dov), TM (TMPC, kub-deformation tswj dov) tuaj yeem txais yuav.
- Thaum lub thickness nyob nruab nrab ntawm 20 - 25mm, N (normalizing), CR (tswj dov), TM (TMPC, kub-deformation tswj dov) tuaj yeem txais yuav.
- Thaum lub thickness nyob nruab nrab ntawm 25 - 35mm, N (normalizing), CR (tswj dov), TM (TMPC, kub-deformation tswj dov) tuaj yeem txais yuav.
- Thaum lub thickness nyob nruab nrab ntawm 35 - 50mm, N (normalizing), CR (tswj dov), TM (TMPC, kub-deformation tswj dov) tuaj yeem txais yuav.
- Thaum lub thickness nyob nruab nrab ntawm 50 - 100mm, N (normalizing), CR (tswj dov), TM (TMPC, kub-deformation tswj dov) tuaj yeem txais yuav. Ntawm lawv, qhov piv txwv ntawm CR (tswj dov) yog 25 tons.

VI. Yam ntxwv

AH32 shipbuilding steel daim hlau muaj qhov zoo toughness, siab zog, muaj zog corrosion kuj, zoo vuam kev ua tau zoo thiab kev ua haujlwm thiab kev ua haujlwm. Nws qhov Mn / C piv yog qhov siab thiab feem ntau yuav tsum siab dua 2.5.

VII. Classification Society Certification

AH32 steel daim hlau tau ntawv pov thawj los ntawm cuaj lub koom haum xws li ABS ntawm Tebchaws Meskas, BV ntawm Fabkis, LR ntawm Tebchaws Askiv, GL ntawm Lub Tebchaws Yelemees, DNV ntawm Norway, RINA ntawm Ltalis, NK ntawm Nyiv, CCS ntawm Tuam Tshoj, thiab KR ntawm South Kauslim.

Nws yuav tsum raug sau tseg tias AH32 steel daim hlau tsim los ntawm cov tuam txhab sib txawv tuaj yeem muaj qee qhov sib txawv hauv cov ntsiab lus tshwj xeeb thiab kev ua haujlwm. Hauv kev siv tiag tiag, kev xaiv thiab tshuaj xyuas yuav tsum tau ua raws li cov qauv tsim nyog thiab cov cai tshwj xeeb. Nyob rau tib lub sijhawm, kev ua haujlwm ntawm cov hlau phaj kuj tseem cuam tshuam los ntawm cov khoom xws li cov txheej txheem tsim khoom thiab kev kho cua sov. Ua ntej yuav khoom thiab siv, nws raug nquahu kom sib txuas lus nrog tus neeg muag khoom lossis cov chaw tsim khoom kom ntseeg tau tias cov hlau phaj ua tau raws li qhov yuav tsum tau ua ntawm cov haujlwm tshwj xeeb.
