RINA DH32 steel phaj yog cov khoom siv hlau uas tau lees paub los ntawm Italian kev faib tawm hauv zej zog (Registro Italiano Navale, RINA) tshwj xeeb rau kev siv hauv kev tsim cov nkoj tsim lossis cov roj tawm sab nrauv.DH32 txhais tau hais tias cov hlau muaj qhov tsawg kawg nkaus yield zog ntawm 315 MPa, ua rau nws. haum rau marine daim ntaub ntawv uas muaj zog thiab durability yog qhov tseem ceeb.
RINA DH32 steel daim hlau yog tsim los tiv thaiv cov xwm txheej hnyav ntawm hiav txwv, muab cov qauv kev ncaj ncees thiab kev ntseeg siab rau lub nkoj lossis cov ntug dej hiav txwv. Txawm hais tias nws yog siv los tsim cov hulls, decks lossis lwm yam tseem ceeb, RINA DH32 steel daim hlau muab qhov zoo tshaj plaws weldability, formability thiab corrosion kuj tsim nyog rau lub marine ib puag ncig.
RINA daim ntawv pov thawj ua kom ntseeg tau tias DH32 steel daim hlau ua tau raws li cov qauv nruj thiab kev nyab xeeb uas yuav tsum tau muaj rau kev siv dej hiav txwv thiab ntug dej hiav txwv. Nws qhia tau hais tias DH32 steel phaj ua tau raws li cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab cov txheej txheem tsim khoom tsim nyog kom ua tau raws li kev lag luam cov cai thiab xyuas kom muaj kev ua tau zoo thiab kev ua haujlwm ntev ntawm cov qauv sab nrauv.
