High Strength Ductile Iron Bar ke thepa ea boemo bo holimo e entsoeng ka ho khetheha bakeng sa likarolo tsa mechini tse hlokang ho tiea le ho sebetsa habonolo. E tsejoang hape e le SG Iron kapa Spheroidal Graphite Iron, thepa ena e kopanya ho tenyetseha ha tšepe le thepa ea mechini e haufi le tšepe. Ka matla a eona a ikhethang, bokhoni bo botle ba ho sebetsa, le bokhoni ba ho damping vibration, ductile iron bar e fetohile khetho e ratoang bakeng sa mefuta e mengata ea lits'ebetso tsa indasteri, ho kenyeletsoa litsamaiso tsa hydraulic, likarolo tsa mochini le likarolo tsa phetisetso ea motlakase.
Ho fapana le tshepe e putsoa, tshepe e ductile e na le graphite ka sebopeho se chitja, e leng se eketsang matla a yona a ho kgomarela le ho hanyetsa kganyetso. Molemo ona wa sebopeho sa micro o e fa botsitso bo phahameng tlasa maemo a boima ba mojaro, e leng se etsang hore e lokele meroalo e sa fetoheng le e fetohang. Di-ductile tshepe di fumaneha ka bophara bo fapaneng mme di ka fanwa maemong a thata kapa a machining ka nepo ho lekana ditlhoko tse fapaneng tsa indasteri.
