Qhov sib txawv ntawm ABS FH47 thiab ABS FH51 steel phaj

ABS FH47 yog ib qho ntxiv - siab - lub zog marine steel phaj ntawv pov thawj los ntawm American Bureau of Shipping (ABS) rau kev thov rau kev tsim nkoj thiab kev siv sab nrauv. Qib "F" qhia tau hais tias nws muaj kev cuam tshuam los ntawm qhov ntsuas kub ntawm -60 degree, kom ntseeg tau tias muaj zog tshwj xeeb rau cov hlab ntsha ua haujlwm hauv cov polar thiab Arctic ib puag ncig. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 460 MPa (67 ksi) thiab lub zog tensile xws li 570 txog 720 MPa (83-104 ksi), nrog rau qhov tsawg kawg nkaus elongation ntawm 17%. Qib no yog tsim tshwj xeeb rau cov khoom siv tseem ceeb hauv cov thawv ntim khoom loj, nrog rau thaj chaw sab saud, cov hlua khi, thiab cov qauv ntev uas muaj lub zog siab thiab kev puas tsuaj yog qhov tseem ceeb.

ABS FH51 yog ib qho ultra- siab- lub zog marine steel phaj kuj tau lees paub los ntawm ABS, tsim los ntawm cov txheej txheem quenching thiab tempering. Zoo li FH47, nws raug kuaj xyuas ntawm -60 degree, nrog rau qhov tsawg kawg nkaus kev xav tau lub zog uas feem ntau nyob ib ncig ntawm 50J (ntev) rau cov qauv thicknesses . Lub "51" qhia txog qhov tsawg kawg nkaus lub zog ntawm 500 MPa (73 ksi) thiab lub zog tensile xws li 610 txog 770 MPa (88-112 ksi), nrog qhov tsawg kawg nkaus elongation ntawm 16%. Cov qib no yog tsim los rau qhov xav tau tshaj plaws load{18}}cov ntaub ntawv kabmob, suav nrog tus kheej- tsa qhov drilling platforms, jack-nce rig ob txhais ceg, thiab cov txheej txheem marine tseem ceeb uas yuav tsum tau muaj zog tshaj qhov sib piv.

ABS FH47 thiab ABS FH51 yog ABS- ntawv pov thawj ultra- siab- lub zog marine steels nrog qhov tshwj xeeb qis- qhov kub thiab txias tau sim ntawm -60 degree, kom ntseeg tau tias kev ua tau zoo nyob rau hauv qhov hnyav tshaj plaws Arctic thiab hnyav marine ib puag ncig. Lawv qhov sib txawv tseem ceeb nyob hauv qib siab: FH47 muaj qhov tsawg kawg nkaus tawm lub zog ntawm 460 MPa nrog lub zog tensile ntawm 570-720 MPa, ua rau nws haum rau siab -lub zog hull cov qauv thiab hnyav- lub luag haujlwm offshore platforms, thaum FH51 muab ntau dua kaum 50 MPa lub zog ncav cuag 610-770 MPa, tsim los rau kev thov ntau daim ntawv thov uas xav tau lub zog-rau-qhov hnyav piv. Ob qib tshwj xeeb tswj cov tshuaj muaj pes tsawg leeg (cov pa roj carbon tsawg dua lossis sib npaug li 0.16%) thiab tswj cov weldability zoo rau cov kev pabcuam tseem ceeb hauv hiav txwv. Qhov kev xaiv ntawm lawv nyob ntawm seb qhov project xav tau qhov sib npaug ntawm FH47 lossis qhov kev ua tau zoo ntawm FH51 rau qhov xav tau ntau yam qauv.
