ABS AH36 Steel Specification yog dab tsi?

Yog tias koj ua haujlwm hauv shipbuilding lossis marine engineering, koj yuav tau hla lub sijhawm "ABS AH36. " Nws yog ib qho kev qhia tshwj xeeb rau ib qho laj thawj: nws yog lub siab - lub zog hlau uas tsim cov pob txha ntawm cov nkoj niaj hnub thiab cov qauv sab nrauv. Cov lus qhia no rhuav tshem ABS AH36 steel specification- txhais li cas, nws cov khoom, thiab yog vim li cas nws thiaj li siv dav.

"ABS AH36" txhais li cas?

Cia peb txiav txim siab lub npe ib feem ntawm daim:

ABSsawv rau lubAmerican Bureau of Shipping, ib tug thawj coj thoob ntiaj teb kev faib pawg neeg. Cov ntawv pov thawj no txhais tau hais tias cov hlau tau raug tsim, sim, thiab pom zoo raws li lawv cov kev cai nruj heev rau kev siv nyob rau hauv marine ib puag ncig.

AW 36yog lub npe qeb. Qhov "A" qhia tias cov hlau no cuam tshuam - kuaj ntawm0℃(32℃F). Lub "H" sawv rauSiab Tensile zog, thiab "36" yog hais txog nws qhov tsawg kawg nkaus yield zog ntawm355 MPa (51,000 psi). Qhov no ua rau nws muaj zog dua li cov qauv me me uas siv hauv kev tsim nkoj, zoo li Qib A.

Ntsiab Specifications: Chemistry thiab Mechanical Properties

ABS AH36 cov lus qhia tshwj xeeb rau kev txwv nruj rau ob qho tib si tshuaj lom neeg muaj pes tsawg leeg thiab kev ua haujlwm txhua yam kom ntseeg tau.

Tshuaj muaj pes tsawg leeg

Kev tswj cov tshuaj muaj pes tsawg leeg ntawm AH36 xyuas kom nws muaj qhov zoo weldability thiab lub zog. Hauv qab no yog cov ntsiab lus tseem ceeb raws li ABS cov cai thiab cov ntaub ntawv kev lag luam:

Element	Max % (Tshwj xeeb)	Lub luag haujlwm hauv Steel
Cov pa roj carbon (C)	0.18	Muab lub zog; txwv kom tuav weldability.
Manganese (Mn)	0.90 - 1.60	Ua kom muaj zog thiab hardenability.
Silicon (Si)	0.10 - 0.50	Ua raws li deoxidizer hauv cov txheej txheem steelmaking.
Phosphorus (P)	0.035	Tswj raws li qhov teeb meem impurity uas tuaj yeem txo qhov toughness.
Sulfur (S)	0.035	Tswj raws li qhov teeb meem impurity uas tuaj yeem txo cov ductility.
Aluminium (Al)	0.015 (min)	Siv rau grain refinement.
Niobium (Nb)	0.02 - 0.05	Pab rau grain refinement thiab nag lossis daus hardening.
Vanadium (V)	0.05 - 0.10	Ntxiv zog los ntawm nag lossis daus hardening.

Carbon Equivalent (CEV)kuj tseem ceeb. Nws yog ib qho qauv siv los kwv yees cov hlau hardenability thiab weldability. Rau AH36, CEV feem ntau yog tswj kom siab tshaj plaws0.38%rau nyias daim hlau los tiv thaiv cov teeb meem xws li txias tawg thaum vuam.

Mechanical Properties

Cov khoom siv kho tshuab ntawm AH36 yog qhov uas nws qhov siab - lub zog muaj zog tiag tiag ci.

Khoom	Tus nqi (Metric)	Tus nqi (Imperial)
Yield zog (Min)	355 MPa rau	51,000 psi
Tensile zog	490 - 620 MPa	71 - 90 tsi
Elongation (Min)	21%	21%

Impact Toughness: Lub Charpy V-Ntch Test

Lub ntsiab feature ntawm AH36 yog nws guaranteed toughness. Cov lus qhia tshwj xeeb yuav tsum dhau Charpy V-qhov ntsuas qhov cuam tshuam ntawm0℃(32℃F). Qhov no ua pov thawj tias cov hlau tuaj yeem nqus tau lub zog tseem ceeb yam tsis muaj kev tawg, uas yog qhov tseem ceeb hauv qhov txias, hnyav marine ib puag ncig.

Qhov xav tau kev cuam tshuam lub zog nyob ntawm steel lub thickness:

Thickness ntau (mm)	Test Temp.	Min. Avg. Zog (Longitudinal)
Tsawg dua los yog sib npaug li 50 mm	0 degree	34 J
>50 - 70 hli	0 degree	41 J
>70 - 100 hli	0 degree	50 J

AH36 vs DH36 thiab EH36

Feem ntau koj yuav hnov AH36 hais nrog DH36 thiab EH36. Lawv muaj lub zog zoo ib yam (355 MPa tawm los, 490-620 MPa tensile), tab sis qhov sib txawv tseem ceeb yog lawv qhov ntsuas kub.

AW 36:Impact kuaj ntawm0℃(32℃F)- haum rau feem ntau - lub hom phiaj nkoj.

DH 36:Impact kuaj ntawm-20 ° F (-4 ° F)- rau cov nkoj ua haujlwm hauv qhov chaw txias dua.

EH 36:Impact kuaj ntawm-40 ° F (-40 ° F)- rau Arctic lossis huab cua txias heev.

Xaiv cov qib zoo yog qhov kev txiav txim siab tsim qauv tsim nyog raws li lub nkoj txoj kev ua haujlwm thiab qhov kub thiab txias.

Ntiaj teb no sib npaug

Vim tias kev tsim khoom hauv nkoj yog kev lag luam thoob ntiaj teb, ABS AH36 specification muaj qhov sib npaug hauv lwm lub koom haum kev faib tawm:

DNV:NV A36

LR (Lloyd's Register):LR/AH36

BV (Bureau Veritas):BV/AH36

CCS (China Classification Society):CCS/A36

NK (Nippon Kaiji Kyokai): K A36

RINA:RI/A 36

Dimensions thiab Supply Forms

AH36 steel feem ntau yog muab los ua daim hlau, tab sis kuj yog cov qauv duab zoo li cov ces kaum thiab qhov muag teeb.

Daim hlau:Feem ntau muaj nyob rau hauv thicknesses ntawm 4mm mus rau ntau tshaj 300mm, dav ntawm 1,200mm mus rau 4,000mm, thiab ntev los ntawm 3,000mm mus rau 12,000mm.

Delivery condition:Muaj peev xwm muab tau rau hauv ntau yam xwm txheej, suav nrog kev ua haujlwm zoo ib yam, thermo- tswj kev ua haujlwm (TMCP), lossis raws li - dov, nyob ntawm qhov tuab thiab cov khoom xav tau.

FAQ

01.Dab tsi yog qhov txawv ntawm ABS AH36 thiab cov hlau me me?

Thawj qhov sib txawv yog lub zog tawm los. ABS AH36 muaj qhov tsawg kawg nkaus yield zog ntawm355 MPa (51,000 psi), uas yog siab dua li tus qauv me me steel (feem ntau nyob ib ncig ntawm 235 MPa). AH36 kuj tseem muaj kev tswj hwm tshuaj nruj dua thiab lav qhov cuam tshuam rau lub zog ntawm 0 degree, ua rau nws zoo dua rau kev siv cov txheej txheem marine tseem ceeb.

02.ABS AH36 steel puas tuaj yeem welded yam tsis muaj preheating?

Thaum AH36 muaj qhov zoo tshaj plaws weldability, preheating yuav tsum tau nyob ntawm lub phaj thickness thiab cov khoom cua sov. Vim nws Carbon Equivalent Value (CEV) ntawm ib ncig ntawm 0.38%, cov phaj tuab (feem ntau tshaj 30mm) feem ntau xav tau preheat ntawm 50℃txog 100℃los tiv thaiv hydrogen-induced txias cracking. Ib txwm ua raws li cov txheej txheem vuam pom zoo (WPS).

03.Dab tsi yog qhov siab tshaj plaws thickness muaj rau ABS AH36 daim hlau?

ABS AH36 steel daim hlau muaj nyob rau hauv ntau yam thicknesses. Feem ntau, lawv tau muab los ntawm4mm txog 300mm. Txawm li cas los xij, rau qhov hnyav hnyav tshaj 150mm, cov khoom siv feem ntau yog muab rau hauv qhov qub lossis thermo-mechanically tswj kev ua tiav (TMCP) kom ntseeg tau tias cov khoom siv kho kom zoo los ntawm tag nrho cov tuab.

04.Kuv puas xav tau ABS ntawv pov thawj rau txhua AH36 steel phaj?

Yog lawm, yuav tsum raug cais raws li "ABS AH36," txhua lub phaj yuav tsum tau tsim nyob rau hauv ib qho kev pov thawj zoo thiab nrog rauDaim ntawv pov thawj zeb xeem (MTC)pom zoo los ntawm American Bureau of Shipping. Daim ntawv pov thawj no txheeb xyuas cov tshuaj muaj pes tsawg leeg, cov txiaj ntsig ntawm kev ntsuas tshuab, thiab kev kho cua sov, kom ntseeg tau tias nws ua tau raws li cov cai nruj rau kev siv dej hiav txwv thiab sab nrauv.
