CCS EH40 Shipbuilding Steel Phaj - Siab -Lub zog Marine Steel rau Arctic thiab huab cua txias ib puag ncig

CCS EH40yog qhov siab dua - lub zog hull cov qauv hlau tau lees paub los ntawm Tuam Tshoj Classification Society (CCS). Qhov "E" nyob rau hauv cov qhab-nees qhia tau hais tias muaj kev cuam tshuam kev xeem ntawm-40 degree, uas txawv ntawm AH40 (0 degree) thiab DH40 (-20℃). "H" txhais tau tias muaj zog dua hlau, thiab "40" yog hais txog qhov tsawg kawg nkaus yield zog ntawm 40 kgf / mm² (kwv yees li 390 MPa).

EH40 yog tsim los siv cov kev coj ua hlau tua nrog kev kho cov nplej zoo thiab cov khoom siv microalloying xws li niobium, vanadium, thiab titanium kom ua tiav cov khoom siv kho tshuab. Cov hlau feem ntau yog muab nkag rau hauv normalized (N) lossis TMCP (Thermo-Mechanical Controlled Processing) mob.

CCS EH40 yog tsim los rau lub nkoj hull cov qauv ua haujlwm hauv Arctic thiab polar cheeb tsam uas kub tuaj yeem poob qis dua -40℃. Cov khoom muaj tib yam 390 MPa yield zog li AH40 thiab DH40 tab sis nrog txhim khu kev qha cuam tshuam toughness ntawm qhov kub thiab txias. Raws li CCS cov tseev kom muaj, EH40 daim hlau yuav tsum xeem dhau Charpy V-notch qhov kev ntsuam xyuas ntawm -40℃nrog qhov nruab nrab nruab nrab lub zog ntawm 41 J rau cov qauv ntev thiab 27 J rau transverse specimens ntawm daim hlau mus txog 50mm thickness.

Peb tau teev CCS EH40 rau lub plhaub plating ntawm ob lub Arctic -chaw nkoj. Lub -40℃kev ntsuam xyuas qhov cuam tshuam tsis tu ncua siab tshaj 50 J. Cov paib li qub txog li 60mm thickness tuaj txog tiaj tus thiab nyob rau hauv siab ntev. Cov neeg soj ntsuam thib peb pom zoo txhua daim ntawv pov thawj zeb.

FAQ

01.Dab tsi yog "EH40" sawv rau hauv nkoj tsim steel?

Qhov "E" qhia txog qhov kev sim ntawm -40℃. "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 EH40 thiab DH40 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: DH40 yog kuaj ntawm -20 degree, thaum EH40 kuaj ntawm -40 degree. EH40 yuav tsum muaj rau cov nkoj ua haujlwm hauv Arctic thiab polar ib puag ncig uas qhov kub thiab txias poob qis dua -20 degree.

03.Yuav tsum tau kho cua sov dab tsi rau CCS EH40 daim hlau?

Rau thickness mus txog 12 hli, normalized, TMCP, los yog quenched & tempered mob yuav tau txais. Rau thicknesses ntawm 12mm thiab 50mm, normalized los yog TMCP yog ib yam. Rau cov thicknesses siab tshaj 50mm, kev faib cov kev cai yuav tsum tau kho ib txwm rau txhua lub phaj kom paub meej tias cov khoom siv sib xws los ntawm tag nrho cov tuab.

04.Yuav ua li cas preheating rau vuam CCS EH40?

EH40 muaj cov pa roj carbon ntau dua li qub - qib zog. Rau thicknesses nyob rau hauv 25 hli, preheat ib ncig ntawm 75-100℃yog raug. Rau cov seem tuab (tshaj 40mm), preheat nyob rau hauv 100-150℃ntau yam. Tsawg-Hydrogen welding consumables yuav tsum tau. Ib txwm ua raws li cov txheej txheem vuam pom zoo nrog kev tswj cov cua sov.
