YST621 surfacing electrode 

 Description: YST621 alkali xing coating, to withstand high impact and air brush the surface of all the parts, also used to weld different materials, such as: manganese steel and structural steel, welding can be used as an overhaul of the buffer layer or the formation of the former The last layer, that work hardening of austenitic deposited metal has excellent impact wear, wear resistance and anti-air brush performance. 

 Uses: used rail infrastructure (rail, road fork plate, gate, sharp track), quarrying, mining facilities (the amount of board crusher, excavators, and grab, hammer, stone machine) and water power stations and other ( hydraulic piston and turbine). 

 Base material: steel with high manganese austenitic
