ZT · SJ401 (silicon-manganese type)
· 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)

· Precautions:
1. Bake at 300 ℃ ~ 350 ℃ for 2h before welding.
2. The rust, oil, moisture and other impurities must be removed at the welding place.
