ABS FQ63 steel phaj yog qib tshwj xeeb ntawm cov hlau tsim los ua kom tau raws li qhov xav tau nruj ntawm kev lag luam xa khoom. Cov phaj no muaj lub zog tshwj xeeb, tawv tawv, thiab weldability, ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov nkoj hla ntau yam kev ua haujlwm.
Chemically, ABS FQ63 steel daim hlau yog tsim los ntawm cov hlau, nrog tswj cov nqi ntawm carbon, manganese, silicon, phosphorus, sulfur, thiab lwm yam alloying ntsiab. Qhov sib npaug ntawm cov ntsiab lus no ua kom cov khoom siv kho kom zoo, tiv thaiv corrosion, thiab ua haujlwm tau zoo.

Kev kho cua sov lub xeev ntawm cov hlau daim hlau no yog ua tib zoo tswj xyuas kom zoo ib yam ntawm cov khoom siv kho tshuab. Feem ntau, lawv tau muab nkag rau hauv cov xwm txheej zoo li qub, uas txhim kho lawv cov toughness thiab cuam tshuam tsis kam.
ABS FQ63 steel phaj muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab thicknesses kom tau raws li cov kev cai tshwj xeeb shipbuilding. Qhov kev hloov pauv no tso cai rau kev siv cov khoom siv tau zoo thiab txo cov khoom pov tseg thaum lub sijhawm tsim kho.
Kev ntsuam xyuas qhov cuam tshuam yog qhov tseem ceeb ntawm cov txheej txheem tswj kom zoo rau ABS FQ63 steel daim hlau. Cov kev ntsuam xyuas no ntsuas cov khoom muaj peev xwm tiv taus cov loads tam sim ntawd thiab kev poob siab, kom ntseeg tau tias nws tsim nyog rau kev siv hauv marine ib puag ncig.
Thawj daim ntawv thov scenarios rau ABS FQ63 steel daim hlau suav nrog kev tsim cov hulls, decks, thiab lwm yam qauv ntawm cov nkoj thiab cov nkoj. Lawv tau dav siv nyob rau hauv ob qho tib si coj mus muag thiab tub rog shipping vim lawv superior kev kawm nyob rau hauv ntau yam loading thiab ib puag ncig tej yam kev mob.
