3.Current:direct current.

4.Performance:anti-porosity and anti-cracking.

Usage:  

1.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.

2.for build-up welding of petrochemical equipments' corrosion-proof layers, stainless clad layers and pressure vessels. 

3.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, etc.

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 with HOOCr21Ni10 as the surface-layer welding band.

Chemical Compositions: 

Cautions: 

 1. Flux must be baked for 2 hours under the temperature of 250~300°c before welding.  

 2. The iron rust, oil contamination and moisture on the weldment must be removed.
