Abstract: One kind of hardfacing austenitic electrode for impact wear resistance,named EKCM50,which is a Fe Mn Cr Mo V alloy system,was developed.Experiments and analysis show that the wear resistance properties of the deposited metal are higher than that of the D256 electrode.After work hardening impact experiments,the hardness of EKCM50 bead weld layer increases from 32HRC to 45HRC.After 40 min of impact wear experiments,the weight loss of deposited metal is very slight.The mechanism of strain hardening and wear resistance of welding material,and the influence of these alloying elements on wear resistance was discussed.
