ABS AH32 Hlau Phaj Rau Shipbuilding

ABS AH32 steel phaj rau shipbuilding yog ib hom high-strength structural steel siv nyob rau hauv shipbuilding thiab tau ntawv pov thawj los ntawm American Bureau of Shipping (ABS)1. Nov yog nws cov yam ntxwv tseem ceeb thiab cov ntaub ntawv tseem ceeb:

 

Tshuaj muaj pes tsawg leeg1:

Cov pa roj carbon (C): Cov ntsiab lus carbon tsawg, feem ntau yog nyob hauv thaj tsam ntawm 0.15-0.18%. Cov ntsiab lus qis dua cov pa roj carbon monoxide pab ua kom lub weldability thiab toughness ntawm cov hlau.

Silicon (Si): Cov ntsiab lus silicon yog 0.15-0.50%, uas tuaj yeem txhim kho lub zog thiab tawv ntawm cov hlau rau qee qhov.

Manganese (Mn): Cov ntsiab lus manganese yog 1.20-1.45%. Manganese yog ib qho tseem ceeb alloying ntsiab uas yuav txhim khu lub zog thiab toughness ntawm hlau.

Phosphorus (P) thiab Sulfur (S): Cov ntsiab lus phosphorus yog txwv rau {{0}}.025% lossis tsawg dua, thiab cov ntsiab lus sulfur yog 0.015% lossis tsawg dua. Cov ntsiab lus tsawg ntawm phosphorus thiab sulfur muaj txiaj ntsig zoo los txhim kho qhov zoo thiab kev ua haujlwm ntawm cov hlau, txo qhov muaj peev xwm ntawm qhov tsis xws luag xws li cov kab nrib pleb thiab suav nrog.

Mechanical zog1:

Yield zog: Lub zog tawm los yog ntau dua lossis sib npaug li 355 MPa, uas txhais tau hais tias cov hlau tuaj yeem nqa tau qee yam tsis muaj deformation.

Lub zog tensile: Lub zog tensile nyob nruab nrab ntawm 490 thiab 630 MPa, qhia tias cov hlau muaj lub zog siab thiab tuaj yeem tiv taus lub zog tensile loj.

Elongation tom qab tawg: Lub elongation tom qab tawg yog ntau dua los yog sib npaug li 21%, qhia txog qhov zoo ductility ntawm cov hlau, uas yog qhov zoo rau kev ua thiab kev tsim.

Qhov zoo:

Zoo toughness: Nws tuaj yeem nqus tau lub zog zoo thaum lub nkoj raug rau sab nraud xws li nthwv dej thiab cuam tshuam, txo qhov kev pheej hmoo ntawm kev puas tsuaj ntawm lub nkoj thiab ua kom muaj kev nyab xeeb ntawm lub nkoj45.

Siab zog: Lub zog siab ntawm cov hlau ua rau lub nkoj tuaj yeem nqa cov khoom hnyav dua, xws li cov khoom thauj thiab cov khoom siv, thiab tuaj yeem tiv taus cov dej hiav txwv zoo dua, txhim kho tag nrho kev ruaj ntseg thiab kev nyab xeeb ntawm lub nkoj45.

Zoo corrosion kuj: Nyob rau hauv ib puag ncig marine, cov hlau tuaj yeem tiv taus cov dej hiav txwv, dej hiav txwv, thiab cov kab mob hauv hiav txwv, ua rau lub neej ntev ntawm lub nkoj.

Kev ua haujlwm vuam zoo: Nws yog qhov yooj yim rau vuam thaum lub sij hawm tsim cov txheej txheem nkoj, thiab cov pob qij txha welded muaj lub zog siab thiab zoo, ua kom muaj kev ncaj ncees thiab kev ntseeg siab ntawm cov qauv nkoj.

Daim ntawv thov4:

Shipbuilding: Nws yog dav siv hauv kev tsim cov hulls, decks, bulkheads, thiab lwm yam qauv ntawm ntau lub nkoj, xws li cov nkoj hla hiav txwv, nkoj ntug hiav txwv, thiab cov nkoj hauv dej hiav txwv.

Offshore engineering: Kuj tseem siv tau rau kev tsim kho ntawm ntug dej hiav txwv platforms, roj rigs, thiab lwm yam marine engineering cov qauv uas xav tau cov ntaub ntawv muaj zog thiab corrosion-resistant.
