Description: 

  JN-HJ260 is a kind of low-Mn high-Si and mid-F flux. It appears light-grey pumice-like particles with the mesh of 10-60 (2-0.3mm). 

 

  During the course of welding, direct-current power supply is adopted, the arc is stable and the appearance of bead is fine.

  It is characterized by small specific weight, low consumption and better appearance. 

Usage: 

  It can be used in the welding of relevant acid-proof stainless structures in conjunction with austenitic stainless steel welding wires, such as HOCr21Ni10(AWS ER308), HOCr20Ni10Ti(AWS ER321), H1Cr13(AWS ER410), H2Cr13(AWS ER420), H3Cr13(AWS ER420J).

 

  It is also used in the submerge-arc build-up welding of all kinds of continuous cast rollers, hot-rolled rollers, mid-or small-sized steel rollers, corrosion-proof shafts, wheels with excellent performance. 

Cautions: 

  1.Impurities on the welding surface must be removed before welding, such as oil stain, moisture, iron rust, etc. 

  2.The flux must be baked for 2 hours under the temperature of 300-400°C before it is used.
