Description: J506Fe is an iron powder low hydrogen potassium electrode. It is used on both AC and DC in all positions. As the coating contains iron powder, it has highly efficient welding and can reduce welding layers. Application: It is used for welding carbon steel and low alloy steel of corresponding strength grade, such as Q345, etc. Chemical composition of weld metal(%):| C | Mn | Si | S | P |
