Kev tu thiab txhua yam khoom ntawm ABS Qib Eh36 shipbuilding steel phaj yog qhov tseem ceeb hauv kev ua kom lub neej ntev, kev cia siab, thiab kev ua tau zoo ntawm cov khoom tshwj xeeb no hauv lub nkoj tsim khoom. Kev xav tau ib puag ncig hauv hiav txwv thiab lub luag haujlwm tseem ceeb uas cov phiaj hlau no ua si hauv kev tsim kho nkoj ua kom muaj kev nkag siab zoo thiab kev tswj hwm ntawm ob qho tib si lawv cov khoom tu thiab cov khoom siv hauv vaj tse.

Kev saib xyuas ntawm ABS Qib Eh36 shipbuilding steel phaj yog cov txheej txheem ceev faj uas yuav tsum tau ua kom muaj kev sib tw thiab kev ua haujlwm. Kev tu tsis tu ncua yog qhov tseem ceeb kom tshem tawm cov ntsev deposits, av, thiab lwm yam kab mob uas tuaj yeem ua kom muaj corrosion. Cov tshuaj ntxuav tshwj xeeb thiab cov txheej txheem yuav tsum tau ua haujlwm los xyuas kom meej qhov ua kom huv si tsis muaj kev puas tsuaj rau saum npoo. Kev tiv thaiv corrosion yog ib qho tseem ceeb, feem ntau nrog rau kev siv cov txheej txheem tiv thaiv xws li epoxy lossis zinc-based formulations. Cov coatings no yuav tsum tau tshuaj xyuas ib ntus kom pom tias muaj kev hnav, puas, lossis delamination thiab kho tam sim ntawd lossis rov siv dua yog tias tsim nyog.

Lwm qhov tseem ceeb ntawm kev saib xyuas yog kev tshuaj xyuas qhov tawg, pitting, lossis lwm yam kev puas tsuaj. Kev kuaj pom pom yuav tsum tau ua raws li niaj hnub ua, ua tiav los ntawm kev sim ntau yam tsis muaj kev puas tsuaj xws li kev kuaj ultrasonic lossis radiographic kuaj ntawm ib ntus. Qhov no yuav pab tau thaum ntxov thiab kho cov teeb meem muaj peev xwm ua ntej lawv nce ntxiv thiab cuam tshuam rau kev ncaj ncees ntawm cov phaj steel.

Hais txog cov khoom siv kho tshuab, ABS Qib Eh36 shipbuilding steel phaj nthuav tawm cov yam ntxwv uas ua rau nws tsim nyog rau kev siv dej hiav txwv. Nws feem ntau ua kom pom lub zog tensile siab, tso cai rau nws tiv taus lub zog loj thiab kev ntxhov siab tshwm sim hauv lub nkoj cov qauv. Lub zog tawm los kuj tseem ceeb, qhia qhov taw qhia ntawm cov khoom pib deform plastically thiab muab qhov tseem ceeb rau kev tsim thiab kev saib xyuas kev nyab xeeb.

Elongation thiab ductility yog ib qho tseem ceeb ntawm cov khoom siv kho tshuab uas ua rau cov phaj hlau nqus tau lub zog thiab deforming yam tsis muaj kev puas tsuaj nyob rau hauv qhov xwm txheej ceev lossis huab cua. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov xwm txheej xws li kev cuam tshuam lossis kev poob siab uas lub nkoj yuav ntsib thaum nws lub neej ua haujlwm. Lub hardness ntawm steel phaj pab txhawb rau nws cov kev tiv thaiv tiv thaiv hnav thiab puas, thaum nws qaug zog tiv thaiv kom nws muaj peev xwm tiv thaiv repetitive loading cycles tsis ntxov ntxov tsis ua hauj lwm.

Impact toughness yog lwm yam cuab yeej cuab tam tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig marine uas qhov kub thiab txias sib txawv thiab muaj zog muaj zog. Ib qho kev cuam tshuam loj heev qhia tau hais tias cov phaj hlau muaj peev xwm tiv taus cov pob txha tawg thiab tsis ua hauj lwm tam sim ntawd thaum muaj kev thauj khoom sai lossis qhov kub thiab txias.

Zuag qhia tag nrho, kev sib xyaw ua ke ntawm kev saib xyuas zoo thiab cov khoom siv zoo tshaj plaws ntawm ABS Qib Eh36 shipbuilding steel phaj yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb, ruaj khov, thiab kev ua haujlwm ntawm cov nkoj tsim siv cov khoom siv no. Kev nkag siab zoo thiab kev tswj hwm ntawm cov haujlwm no yog qhov tseem ceeb rau kev ua tiav thiab txhim khu kev lag luam ntawm cov nkoj hauv qhov nyuaj marine ib puag ncig.
