Lawng leh Marine engineering lama brass rod hman a ni

Marine environment-a corrosiveness chak tak leh salt spray characteristic sang tak hian material-te corrosion resistance chungchangah thil tih tur khauh tak a siam a ni. Brass rod (a bik takin naval brass, HSn70-1 ang chi), tin awm zat avang hian a chung lamah oxide film nghet zawk a siam a, chu chuan lawng propeller, tuifinriat tui pipe leh condenser tube sheet siamna atana hmanraw duh ber a ni. Entirnan, sangha mantu lawng chi khat propeller hi HSn70-1 brass atanga siam a ni a, tuifinriat tuiah kum khata a corrosion rate chu 0.02mm chauh a ni a, hei hi carbon steel pangngai 0.5mm aiin a hniam zawk hle a, hei hian enkawlna senso nasa takin a tihtlem phah a ni.
