Impact Toughness
Tus yam ntxwv txhais ntawm DH36 yog nws Charpy V-notch cuam tshuam toughness kev ua tau zoo. Cov qhab-nees "D" qhia tau hais tias kev ntsuam xyuas cuam tshuam yog ua ntawm-20 ° F (-4 ° F).
Kev cuam tshuam lub zog xav tau sib txawv nrog cov phaj thickness:
| Thickness Ntau | Longitudinal Zog (ft-lbs) | Transverse Zog (ft-lbs) |
|---|---|---|
| 4.76-50.8 hli | 25 min (ntau tshaj) | 17 (min avg) |
| 50.83-71.1 hli | 30 min (muab avg) | 20 min (muab avg) |
| 71.15-150 hli | 37 (min avg) | 25 min (ntau tshaj) |
AH36 vs. DH36: Kev sib piv ncaj qha
Thaum AH36 thiab DH36 sib koom ntau yam khoom, lawv qhov sib txawv tseem ceeb nyob rau hauv qhov kub thiab txias uas cuam tshuam qhov hnyav yog lav:
| Feature | AW 36 | DH 36 |
|---|---|---|
| Qib Qib | A (kev cuam tshuam kuaj ntawm 0 degree) | D (kev cuam tshuam ntawm -20 degree) |
| Impact Test Temperature | 0℃(32℃F) | -20 ° F (-4 ° F) |
| Yield zog (min) | 355 MPa rau | 355 MPa rau |
| Tensile zog | 490-620 MPa | 490-620 MPa |
| Elongation (min) | 22% | 22% |
| Tshuaj muaj pes tsawg leeg | Cov kev txwv zoo sib xws | Cov kev txwv zoo sib xws |
| Weldability | Zoo heev | Zoo heev |
| Carbon sib npaug | Tsawg dua lossis sib npaug li 0.38% | Tsawg dua lossis sib npaug li 0.38% |
| Tej kev siv | General hull lug, sab saum toj decks | Qhov tseem ceeb hull qauv, ib puag ncig txias, offshore |
Cov ntsiab lus ntawm qhov sib txawv
Impact kub: Qhov sib txawv tseem ceeb ntawm AH36 thiab DH36 yog Charpy V-qhov ntsuas kub ntsuas. AH36 yuav tsum ua kom tau raws li qhov xav tau ntawm lub zog ntawm 0 degree, thaum DH36 yuav tsum ua tau raws li qhov xav tau ntawm -20℃-a 20℃qis dua.
Kev thov kom haum: DH36 yog qhov zoo dua rau cov hlab ntsha thiab cov qauv ua haujlwm hauv qhov chaw txias dua lossis qhov chaw muaj zog dua qhov yuav tsum tau muaj rau cov txheej txheem tseem ceeb.
Nqi: Vim qhov kev ntsuam xyuas nruj dua qhov yuav tsum tau ua, DH36 feem ntau nqa tus nqi qis dua AH36.
Weldability: Ob qib muaj qhov zoo sib xws zoo weldability yam ntxwv thiab tuaj yeem welded siv cov hlau muab tub lim zoo tib yam thiab cov txheej txheem.
Vim li cas thiaj xaiv ABS DH36 shipbuilding steel?
ABS DH36 sawv cev rau ntau yam, siab - lub zog shipbuilding hlau uas sib txuas cov khoom siv kho tshuab zoo nrog cov qib qis dua - qhov kub thiab txias. Nws tau lees paub qhov ua tau zoo ntawm -20℃ua rau nws muaj kev ntseeg siab rau kev thov rau kev siv dej hiav txwv. Thaum muab piv rau AH36, qhov sib txawv ntawm qhov tseem ceeb yog qhov ntsuas qhov ntsuas qis qis, ua rau DH36 qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas yuav tsum tau ua kom muaj zog hauv qhov chaw txias dua. Ob qib muab kev zoo weldability, ua rau lawv tseem ceeb hauv kev lag luam shipbuilding thoob ntiaj teb.
