Description: J507FeNi is a low alloy steel electrode with iron powder and low hydrogen coating. It can be used for all-position welding with AC and DC. The performance stability of AC welding is inferior to that of DC welding Application: Used for welding medium carbon steel and low temperature steel pressure vessels, such as 16MnDR, etc. Chemical composition of weld metal(%):| C | Mn | Si | Ni | S | P |
