Casting properties of ASTM A128 Gr. E1 steel modified with Mn-alloying and titanium ladle treatment
This work aims to produce a high manganese steel with more refined austenite grains and better wear resistance without sacrificing the toughness and tensile properties by Mn alloying and Ti ladle treatment in comparision to ASTM A128 Gr. E1 steel (1.0C-13Mn) that is mostly used in the mining industr...
