ABS Shipbuilding Steel Phaj: Ua tiav Daim Ntawv Qhia rau AH32, DH32 & EH36 Qib rau Kev Tsim Kho Marine
To taub cov nuances ntawm siab - lub zog hull structural steel yog qhov tseem ceeb rau kev nyab xeeb, kev ua neej ntev, thiab kev ua raws cai.Thaum tsim cov dej hiav txwv- mus rau cov nkoj, cov ntug dej hiav txwv, lossis cov nkoj tshawb nrhiav Arctic, xaiv cov phaj hlau zoo tsis yog hais txog lub zog xwb- nws yog hais txog kev ciaj sia.
Hauv phau ntawv qhia no, peb dhia tob rau hauvABS - ntawv pov thawj shipbuilding steel daim hlau, tshwj xeeb sib piv cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, kev ua haujlwm qis - qhov kub thiab txias, thiab cov kev siv zoo ntawmQibAH32, DH32, thiab EH36.
Vim li cas ABS Classification Matters
CovAmerican Bureau of Shipping (ABS)yog ib lub ntiaj teb cov kev faib ua pawg thawj coj. ABS daim ntawv pov thawj xyuas kom meej tias cov hlau phaj tau dhau los ua nruj thib peb -kev tshuaj ntsuam xyuas rauchemical muaj pes tsawg leeg, mechanical zog, thiab weldability .
Siv ABS- pom zoo steel yog qhov yuav tsum tau ua rau kev xa khoom thoob ntiaj teb thiab cov haujlwm sab nrauv los lav cov qauv kev ncaj ncees nyob rau hauv cov dej hiav txwv dynamic.
Tshuaj muaj pes tsawg leeg
Thaum lub nkoj tsim cov hlau tsis tshua muaj tsawg- carbon los xyuas kom meej weldability zoo, qhov sib ntxiv ntawm cov hlau xws li Manganese (Mn), Niobium (Nb), thiab Vanadium (V) txhim kho lub zog yam tsis muaj kev sib tw toughness.
Standard Chemical Requirements (Ladle Analysis):
| Element | AH32 / DH32 / EH36 | Muaj nuj nqi |
|---|---|---|
| Cov pa roj carbon (C) | Tsawg dua lossis sib npaug li 0.18% | Xyuas kom weldability |
| Silicon (Si) | 0.10 – 0.50 % | Deoxidizer |
| Manganese (Mn) | 0.90 – 1.60 % | Nce zog & hardness |
| Phosphorus (P) | Tsawg dua lossis sib npaug li 0.030% | Tswj kom tsis txhob muaj qhov txias txias |
| Sulfur (S) | Tsawg dua lossis sib npaug li 0.030% | Txhim kho toughness |
| Aluminium (Als) | Ntau dua lossis sib npaug li 0.015% | grain refiner |
| Niobium (Nb) | 0.02 – 0.05 % | Grain refinement & nag xob nag cua ntxiv dag zog |
Lus Cim: Cov hlau no raug tua (tag nrho deoxidized) thiab ua raws li kev coj ua zoo, uas yog qhov tseem ceeb rau kev cuam tshuam zoo ib yam.
Mechanical Properties & Physical Performance
Tag nrho peb qib muaj lub zog tensile siab, tab sis lawv qhov kev ua tau zoo sib txawv heev thaum kub poob.
ABS Qib AH32
Yield zog:Ntau dua lossis sib npaug rau 315 MPa (46 ksi)
Tensile zog:440-590 MPa
Elongation:Ntau dua lossis sib npaug li 22%
Impact Test Temperature: 0℃(32℃F)
Qhov zoo tshaj plaws rau:Sab hauv cov qauv, deckhouses, thiab cov nkoj ua haujlwm hauv huab cua sov.
ABS Qib DH32
Yield zog:Ntau dua lossis sib npaug rau 315 MPa (46 ksi)
Tensile zog:440-590 MPa
Elongation:Ntau dua lossis sib npaug li 22%
Impact Test Temperature: -20 ° F (-4 ° F)
Qhov zoo tshaj plaws rau:Hull shells, cargo tuav, thiab lub caij ntuj no navigation nyob rau hauv freezing zones.
ABS Qib EH36
Yield zog:Ntau dua lossis sib npaug rau 355 MPa (51 ksi) - * Siab dua AH / DH32 *
Tensile zog:490-620 MPa
Elongation:Ntau dua lossis sib npaug li 21%
Impact Test Temperature: -40 ° F (-40 ° F)
Qhov zoo tshaj plaws rau:Icebreakers, Arctic nkoj, thiab siab - thaj chaw muaj kev ntxhov siab xws li kev sib tw.
Kev pom zoo:Thaum AH32 thiab DH32 sib koom tib lub zog (315 MPa),EH36 muaj 12% siab zog tawm los (355 MPa)ua ke nrog tsis tshua muaj siab -kub resilience.
