Kakaretso ea Liphaephe tsa Tšepe tsa Ductile
Ho se ho fetile dilemo tse fetang 70 ho tloha ha ho qaptjoa phaephe ya tshepe e ductile ka bo-1940. Ka matla a yona a hodimo, ho lelefala ha yona ho hoholo, ho hanyetsa mafome, ho hanyetsa ho tshoha, kaho e bonolo le dikarolo tse ding tse ngata tse ntle, phaephe ya tshepe e ductile ke kgetho e ntle ka ho fetisisa lefatsheng la kajeno bakeng sa ho tsamaisa metsi le kgase ka polokeho. Tshepe e ductile, eo hape e bitswang tshepe e nang le maqhutsu kapa tshepe ya graphite ya spheroidal, e kgethollwa ka boteng ba graphite ya spheroidal di-castings tse hlahang.
