Description: J501Fe is a carbon steel electrode with iron powder and low hydrogen potassium coating. Both AC and DC can be used for all-position welding. Its characteristic is that the coating contains iron powder with excellent welding performance. The deposited metal has good strength toughness. Application: It is used for welding carbon steel and low alloy steel of corresponding strength grade, such as Q345, Q345R, etc. Chemical composition of weld metal(%):| C | Mn | Si | S | P |
