· Conform to: GB / T5293-1999, F4A2-H08A

AWS A5.17, F6A0-EL12

· Description: SJ401 is a silicon-manganese sintered flux, which is an acidic flux. It is gray-brown to black round particles with a particle size of 2.0-0.28mm (10-60 mesh). It can be used for both AC and DC. The welding wire is connected to the positive electrode during DC welding. The welding process has good performance and high anti-porosity performance.

· Application: With H08A welding wire, it can weld low carbon steel and some low alloy steel, used for welding metal structures such as locomotives, mining machinery and so on.

· Mechanical properties of deposited metal (according to GB / T5293-1999, F4A2-H08A)
