ABS FQ51 marine steel daim hlau yog cov ntaub ntawv tshwj xeeb uas tsim los ua kom tau raws li qhov xav tau nruj ntawm kev lag luam shipbuilding. Cov phaj no muaj kev sib xyaw ua ke ntawm cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov yam ntxwv kho cua sov uas ua rau lawv haum rau ntau yam kev siv dej hiav txwv.

ABS FQ51 steel phaj tau dhau los ua cov txheej txheem kev kho cua sov kom ua tiav lawv cov khoom siv kho tshuab uas xav tau. Cov txheej txheem no feem ntau cuam tshuam nrog normalizing lossis quenching thiab tempering, nyob ntawm seb cov kev xav tau tshwj xeeb ntawm qib steel thiab daim ntawv thov.
Kev ntsuam xyuas qhov cuam tshuam yog qhov tseem ceeb ntawm cov txheej txheem tswj kom zoo rau ABS FQ51 steel daim hlau. Cov kev ntsuam xyuas no tau ua los ntsuas cov khoom siv tiv thaiv qis -kub brittleness, kom ntseeg tau tias nws muaj kev ntseeg siab hauv qhov chaw txias.
Cov ntawv thov tseem ceeb ntawm ABS FQ51 steel daim hlau yog nyob rau hauv kev tsim cov nkoj thiab lwm cov nkoj hauv hiav txwv. Lawv lub zog siab thiab corrosion kuj ua rau lawv tsim nyog siv rau hauv cov qauv hull, decks, bulkheads, thiab lwm qhov chaw uas xav tau kev ua haujlwm zoo dua thiab kev ua haujlwm.
