CCS FH40 Shipbuilding Steel Phaj - Siab -Lub Zog Marine Steel rau Ib puag ncig zoo heev Polar

CCS FH40 yog qhov siab tshaj - qib siab dua - lub zog hull cov qauv hlau tau lees paub los ntawm Tuam Tshoj Classification Society (CCS). Qhov "F" nyob rau hauv cov qhab-nees qhia tau hais tias muaj kev cuam tshuam kev xeem ntawm-60 degree, qhov ntsuas qhov ntsuas kub qis tshaj plaws ntawm cov qib siab dua - lub zog shipbuilding steel qib. "H" txhais tau tias siab dua - lub zog steel, thiab "40" yog hais txog qhov tsawg kawg nkaus tawm lub zog ntawm 40 kgf / mm² (kwv yees li 390 MPa).

FH40 yog tsim los siv cov kev coj ua hlau tua nrog cov hmoov nplej zoo thiab cov khoom siv microalloying xws li niobium, vanadium, thiab titanium kom ua tiav cov khoom siv kho tshuab. Cov hlau yog muab rau hauv normalized, TMCP (Thermo-Mechanical Controlled Processing), los yog quenched thiab tempered mob nyob ntawm thickness thiab daim ntawv thov. Cov ntsiab lus carbon ntawm FH40 yog txwv rau 0.16% max, qis dua AH40 / DH40 / EH40 (0.18% max), nrog kev tswj hwm nruj dua phosphorus thiab sulfur (0.025% max txhua).

CCS FH40 yog tsim los rau qhov xav tau ntau tshaj plaws nyob rau hauv marine ib puag ncig: Arctic thiab polar cheeb tsam uas kub tuaj yeem poob qis dua -60℃. Cov khoom muaj tib yam 390 MPa yield zog li AH40, DH40, thiab EH40 tab sis nrog txhim khu kev qha cuam tshuam toughness ntawm huab cua kub. FH40 steel yog siv nyob rau hauv icebreakers, polar mov nkoj, thiab ice-class ships ua hauj lwm nyob rau hauv lub harshest tej yam kev mob nyob rau hauv lub ntiaj teb no.

FAQ

01.Dab tsi yog "FH40" sawv rau hauv shipbuilding steel?

Qhov "F" qhia txog kev sim ntawm -60℃. "H" sawv cev rau cov hlau muaj zog dua. "40" yog hais txog qhov tsawg kawg nkaus tawm lub zog ntawm 40 kgf / mm², kwv yees li 390 MPa hauv metric units.

02.Qhov txawv ntawm FH40 thiab EH40 yog dab tsi?

Ob leeg muaj qhov tsawg kawg nkaus tawm lub zog (390 MPa) thiab tensile zog (510 - 650 MPa). Qhov txawv yog qhov ntsuas kub ntawm qhov ntsuas kub: EH40 yog kuaj ntawm -40 degree, thaum FH40 kuaj ntawm -60 degree. FH40 kuj tseem muaj cov txheej txheem tshuaj lom neeg nruj dua: qis carbon (0.16% vs 0.18%), qis phosphorus thiab sulfur (0.025% vs 0.035%), thiab ntau dua nickel (0.80% vs 0.40%). FH40 yuav tsum muaj rau cov dej khov nab kuab thiab cov nkoj ua haujlwm hauv Arctic lub caij ntuj no.

03.Yuav tsum tau kho cua sov dab tsi rau CCS FH40 daim hlau?

FH40 daim hlau yuav tsum tau muab nkag rau hauv qhov qub, TMCP, lossis quenched thiab tempered mob nyob ntawm thickness. Kev faib tawm cov cai yuav tsum tau tua tag nrho thiab nplua -kev kho cov nplej . Tsis zoo li cov qib qis, FH40 tsis tuaj yeem muab tau raws li -rolled condition rau tej thickness vim hais tias qhov -60℃tej yam yuav tsum tau xav kom tswj kev ua.

04.Yuav ua li cas preheating rau vuam CCS FH40?

FH40 muaj cov pa roj carbon ntau dua (0.40% max rau t Tsawg dua lossis sib npaug rau 50mm, 0.42% rau 50
