Ultrasteel is characterized by its higher cleanness and ultra-finegrain, thus it has higher strength, toughness and longer life even without addition of more alloying elements.
With the deeper knowledge of ultrafinegrainsteel, the process of refinement has became one of the main methods to increase mechanical properties of steel availably nowadays.
