Raws li qhov sib txawv thiab kev ua haujlwm, cov qauv hull yuav tsum siv cov hlau uas muaj zog sib txawv thiab cov khoom tiv thaiv corrosion. Nws feem ntau suav nrog cov hauv qab no:
(1) Rolled phaj: tsuas yog siv rau cov qauv loj hauv cheeb tsam xws li hauv qab phaj thiab lawj, nrog lub zog siab thiab zoo toughness.
(2) Ntu steel: feem ntau yog siv rau lub plhaub thav duab, kev txhawb nqa thiab kev sib txuas nrog lub zog siab thiab nruj.
(3) Vuam steel: siv rau vuam ntau yam txuas ntawm cov qauv hull, nrog zoo vuam kev ua tau zoo thiab corrosion kuj.
(4) Corrosion-resistant steel: feem ntau yog siv rau underwater qhov chaw ntawm lub hull, xws li hauv qab ntawm lub nkoj, rudder hniav, thiab lwm yam., nrog zoo heev corrosion kuj.
(5) Cov hlau tshwj xeeb: xws li cov hlau muaj zog, hnav-tiv taus steel, thiab lwm yam, rau lub sijhawm tshwj xeeb thiab kev xav tau kev ua haujlwm, tuaj yeem txhim kho lub zog thiab ua haujlwm ntev ntawm cov qauv hull.
