tlhokeho ya tshebetso
(1) Matla a phahameng: ka kakaretso, matla a tlhahiso ea eona a ka holimo ho 300MPa.
(2) Matla a phahameng: bolelele bo hlokahalang ke 15% ~ 20%, 'me tšusumetso e matla mocheso oa kamore e kholo ho feta 600kJ/m~800kJ/m.Bakeng sa likarolo tse kholo tse cheselitsoeng, ho hlokahala ho thata ho hoholo ha fracture.
(3) Ts'ebetso e ntle ea welding le ts'ebetso e batang ea ho theha.
(4) Mocheso o tlase o batang oa phetoho ea brittle.
(5) Khanyetso e ntle ea kutu.
3. Litšobotsi tsa sebopeho sa phala ea galvanized
(1) Khabone e tlase: ka lebaka la litlhoko tse phahameng tsa ho thatafala, ho cheseha le ho etsa ts'ebetso e batang, khabone ha e na ho feta 0.20%.
(2) Manganese e thehiloeng alloy element e eketsoa.
(3) Ho eketsoa ha niobium, titanium kapa vanadium: palo e nyenyane ea niobium, titanium kapa vanadium e etsa carbide e ntle kapa carbonitride ka tšepe, e leng se loketseng ho fumana lijo-thollo tse ntle tsa ferrite le ho ntlafatsa matla le ho tiea ha tšepe.Ho phaella moo, ho eketsa palo e nyenyane ea koporo (≤ 0.4%) le phosphorus (hoo e ka bang 0.1%) e ka ntlafatsa ho hanyetsa ha kutu.Ho kenyelletsa likaroloana tse nyane tsa lefats'e tse sa tloaelehang ho ka tlosa sebabole le khase, ho hloekisa tšepe, le ho ntlafatsa ho tiea le ho sebetsa.
