RINA Qib E500 yog lub siab -lub zog, ib txwm ua lub nkoj tsim steel phaj ntawv pov thawj los ntawm Italian faib pawg zej zog, RINA. Nws yog tsim los rau cov txheej txheem tseem ceeb hauv kev tsim cov nkoj niaj hnub thiab cov qauv hauv ntug dej hiav txwv uas tshwj xeeb tshaj yog lub zog, tawv, thiab weldability yuav tsum tau tiv taus qhov hnyav marine ib puag ncig thiab hnyav hnyav.
RINA E500 ntxiv muaj zog Chemical Composition nyob rau hauv Tempering thiab quenching
