ABS Shipbuilding Material Marine Qib Steel Phaj

Cov qauv tshwj xeeb thiab cov tseev kom muaj rau ABS DNV Pov Thawj DH32 Steel Phaj yog raws li hauv qab no:

 

Tshuaj muaj pes tsawg leeg:

Cov pa roj carbon (C): Cov ntsiab lus carbon feem ntau yuav tsum tsawg dua lossis sib npaug rau 0.18% los ntawm huab hwm coj. Cov pa roj carbon yog ib qho tseem ceeb uas cuam tshuam rau lub zog thiab hardness ntawm cov hlau, tab sis cov pa roj carbon ntau tuaj yeem txo cov hlau weldability thiab toughness.

Manganese (Mn): Cov ntsiab lus manganese yuav tsum nyob hauv thaj tsam ntawm 0.90% txog 1.60%. Manganese pab txhim kho lub zog thiab toughness ntawm cov hlau thiab kuj muaj txiaj ntsig zoo rau cov tawv tawv.

Silicon (Si): Cov ntsiab lus silicon feem ntau yog txwv tsawg dua lossis sib npaug rau 0.50%. Silicon tuaj yeem txhim kho lub zog thiab oxidation tsis kam ntawm cov hlau, tab sis ntau dhau ntawm silicon tuaj yeem ua rau brittleness.

Phosphorus (P) thiab Sulfur (S): Cov ntsiab lus siab tshaj plaws ntawm phosphorus yog {{0}}}.035%, thiab leej faj yog 0.035%. Ob lub ntsiab lus no yog impurities nyob rau hauv cov hlau, thiab cov nyiaj ntau dhau tuaj yeem ua rau cov pob txha tawg thiab txo qhov corrosion ntawm cov hlau.

Aluminium (Al): Cov ntsiab lus txhuas yuav tsum ntau dua lossis sib npaug rau 0.015%. Aluminium yog siv los ua deoxidizer nyob rau hauv cov txheej txheem steelmaking thiab tuaj yeem txhim kho qhov toughness thiab corrosion kuj ntawm cov hlau.

Lwm yam Alloying Elements: Tseem muaj cov kev cai rau lwm yam alloying ntsiab xws li niobium (Nb), titanium (Ti), vanadium (V), nickel (Ni), tooj liab (Cu), chromium (Cr), molybdenum (Mo). Piv txwv li, cov ntsiab lus ntawm niobium feem ntau yog nyob rau hauv thaj tsam ntawm {{0}} 02% rau 0.05%, thiab cov ntsiab lus ntawm vanadium yog 0.05% txog 0.10 %.

Mechanical Properties:

Yield zog: Lub zog tawm los ntawm DH32 steel phaj yuav tsum siab dua lossis sib npaug ntawm 315 MPa. Yield zog yog ib qho tseem ceeb qhia txog cov khoom muaj peev xwm tiv thaiv deformation nyob rau hauv load.

Tensile zog: Lub zog tensile yuav tsum nyob rau hauv thaj tsam ntawm 440 MPa rau 590 MPa. Lub zog tensile qhia txog qhov siab tshaj plaws uas cov khoom tuaj yeem tiv taus ua ntej tawg.

Elongation: Lub elongation ntawm kev tawg yuav tsum tsis pub tsawg tshaj li ib qho nqi (feem ntau nyob ib ncig ntawm 22% rau 200 hli ntsuas qhov ntev thiab 26% rau 50 hli ntsuas qhov ntev). Elongation qhia qhov ductility ntawm cov khoom, uas yog ib qho tseem ceeb rau cov hlau ua thiab kev ua tau zoo.

Impact Toughness: Cov phaj hlau yuav tsum tau ua kom tau raws li cov kev cai tshwj xeeb rau kev cuam tshuam toughness ntawm qhov sib txawv kub. Piv txwv li, ntawm qhov kub thiab txias (xws li -20 degree), qhov cuam tshuam lub zog tus nqi yuav tsum ncav cuag ib theem kom ntseeg tau tias cov hlau ua tau zoo hauv qhov chaw txias.

Dimensions thiab Tolerances:

Thickness: Lub thickness ntawm cov hlau phaj feem ntau yog nyob ntawm ob peb millimeters mus rau ob peb puas millimeters, thiab muaj kev zam tshwj xeeb rau cov tuab. Piv txwv li, lub thickness kam rau ua yuav tsum nyob rau hauv ib tug tej yam ntau yam los xyuas kom meej lub uniformity ntawm steel phaj thickness thiab ua tau raws li tus tsim thiab tsim yuav tsum tau.

Dav thiab Ntev: Qhov dav thiab ntev ntawm cov hlau phaj kuj muaj qhov tshwj xeeb qhov yuav tsum tau thiab kam rau ua, uas tau txiav txim siab raws li qhov xav tau ntawm cov khoom siv nkoj sib txawv thiab kev siv thev naus laus zis.

 

 

 

 

 

Specification peb muab:

Thickness	2-200 hli
Dav	1000-4000 hli
Ntev	5000-15000 hli

American Bureau of Shipping (ABS) yog ib lub koom haum kev faib dej hiav txwv tau tsim nyob rau xyoo 1862. Nws lub luag haujlwm tseem ceeb ntawm ABS yog los xyuas kom meej tias ABS-qib cov nkoj thiab cov qauv hauv hiav txwv ua tau raws li cov kev cai tsim, kev tsim kho thiab kev tshawb fawb ib ntus.
