Description of Welding Flux For Hardfacing: 

JN-HJ107 is a kind of smelting-type non-Mn mid-Si and mid-F flux,which appears grey blue pumice-like particles with the mesh of 10-60 (2.0-0.3mm) or 8-40 (2.5-0.45mm) and uses direct-current supply.


When used under higher electric arc voltage, the penetration is shallow, the arc is stable and the appearance of weld is pleasing to the eye.


The consumption of flux is low and it is easy to detach the welding slag.


As it contains much CaF2 and Cryolite is also added to, its ability of anti-porosity and anti-cracking is greatly improved.


The ingredient Cr2O3 not only plays the floating petrochemical role but also reduces the loss of Cr in the stainless steel welding process.


Usage of Welding Flux For Hardfacing:  

Excellent clad layers can be gained when it is used in the build-up welding in conjunction with appropriate welding wires or solder strips, such as HOCr21Ni10(AWS ER308), HOCr20Ni10Ti(AWS ER321), HOOCr21Ni10(AWS ER308L), HOOCr24Nb, HOCr16Mn16, etc.


Suitable for the build-up welding of petrochemical equipments' corrosion-proof layers, stain-less clad layers and pressure vessels.


In conjunction with HOCr16Mn16, it can be used in the build-up welding of the track switch of high manganese steel (Mn13) and welding of Nb-contained stainless steel, ect.


Performance of Surfacing Layers:   

It can be used in the transition-layer welding in conjunction with HOOCr26Ni12 and in the build-up welding of 50mm-thick 18MnMoNb steel plate in conjunction withHOOCr21Ni10(AWS ER308L) as the surface-layer welding band.



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


2.The flux must be baked for 2 hours under the temperature of 250-300°C before it is used.

Q:What soldering flux is used for manual welding of SMT components?
BGA solder paste can solve your problem, no corrosion, safety, environmental protection, do not understand, and then Baidu button to help you solve.
Q:What welding flux for electroslag welding material Q345B
H08Mn or H10Mn2345 material with Mn, if it is in welding technology melting mouth electroslag welding machine, welding wire with flux is 2.5, 431, if it is in welding technology with wire electrode electroslag welding, welding wire is 1.6, with Mn and Mo, the flux is generally JF600, if not, you can use 431 instead
Q:What are the roles of flux in soldering?
Play a catalytic role in speeding up solder melting.
Q:How about Jin Yuancheng's soldering flux and bath water?
What you can use is the best
Q:The soldering flux is good or good hydrochloric acid with sulfuric acidWhat is the sulfuric acid soldering flux or hydrochloric acid, which is easy to use?

Q:What are the hazards of soldering flux?
1, the substrate has a certain corrosive;2, reduce conductivity, resulting in migration or short-circuit;3. Non conductive solid such as the contact part of the invading element can cause poor bonding;4, resin residue is too much, adhesion, dust and debris;5, affect the reliability of the product.
Q:What flux should be used in the national standard for nickel plated products?
Using stainless steel flux is OK
Q:How are the nickel plating parts treated by flux corrosion?
There are two possible reasons that flux change nickel layer:First, nickel layer of high temperature discoloration, the need to use acid activation, sulfuric acid and hydrofluoric acid can be used;Two, the flux of organic residues, which need to be cleaned with organic solvents, such as alcohol, gasoline, acetone and so on.
Q:What are the commonly used fluxes?
Flux is divided into smelting flux and non smelting flux. Non smelting flux is divided into bonded flux and sintered flux. Our country is mainly smelting flux, and the most used in smelting flux is HJ431.
Q:Why does the flux smell of kerosene?
Because of kerosene, BS-10 has 4% kerosene
