Description: 

  1. JN-SJ101 is fluorine alkali type sintered flux.

  2.Grain size:10-60(2.0-0.3mm)  meshes.

  3.Performance:

    a. easy to deslag.

    b. Sulfur removal, phosphor removal and anti-rust.

    c. fine appearance of weld (even in the narrow gap of deep slope entrance).

    d. weld metal: good plastic toughness, low hydrogen content diffusion and fine properties of cold, heat and crack resistance.

Usage: 

  1. for low carbon, low alloy and pipeline steel.

  2. for thick wall  structures of different high-tensile steels .

Cautions :  1.The oil contamination, moisture, iron rust and other foreign substances must be removed from the welding  joint .  2.It is better to weld under direct  current .  3.Welding flux must be baked under  250-300°C for more than 2 hours before usage.
