Description: J506 is a carbon steel electrode with low hydrogen potassium coating. AC and DC dual-purpose, can be welded in all positions. The performance stability of AC welding is inferior to that of DC welding. Deposited metal has good mechanical properties and crack resistance. Application: Used for welding medium carbon steel and low alloy steel, such as Q345, 09Mn2Si, etc. Chemical composition of weld metal(%):| C | Mn | Si | S | P |
