Alloy Cast Steel e Sebelisitsoeng Bakeng sa Likarolo Tsa ho Lahlela

Low alloy cast steel e bua ka tšepe ea alloy cast e nang le khabone e ka tlase ho 0.45% le kakaretso ea likarolo tse ling tse sa feteng 5%. Tšepe e tlase ea alloy cast e na le matla a phahameng, ho tiea ho hotle le ho thatafala. Tšepe ea alloy cast e tlase hangata e na le likarolo tse kopaneng tse kang manganese, chromium, koporo, nickel, molybdenum le vanadium. Li na le tšusumetso e matla 'me li ka fumana thepa e ntle ea mochini ka kalafo ea mocheso. Ho hanyetsa kutu le ho roala ha tšepe ea tšepe e tlaase ea alloy e molemo ho feta carbon steel, e ka fokotsang boima ba likarolo le ho eketsa bophelo ba tšebeletso.
