YST622 surfacing electrode 

 Description: YST622 is xing rutile coating base, for all components to withstand high impact welding, surfacing, or to allow the formation of the final layer of deposited metal is austenitic, with excellent impact resistance and impact wear capacity. Used for repair parts or new parts of the protection. 

 Uses: Railway infrastructure (rail, road fork plate, gate, sharp track), quarrying, mining facilities (the amount of board crusher, excavators, and grab, hammer, stone machine). 

 Base material: steel with high manganese austenitic
