Product model: KY911 wear-resistant flux cored wire Product specifications: 1.2mm 1.6mm 15kg / box Post-weld hardness: HRC 65-70° Scope of application: It is suitable for high hardness and hard surface treatment of parts with high wear and high impact. It is suitable for surfacing welding with strong abrasion resistance. It has wide application range and high quality. Metal composition (%): C 3.00-6.00; Mn 2.00-3.00; B 5.00-8.00; Cr 20.00-25.00; Ni 2.00-3.00; Mo 2.00-3.00 Precautions: 1. Adopt DC reverse connection; 2. When welding, the flow rate of CO2 gas should be 20~25L/min; 3. The dry elongation of the wire should be controlled within the range of 15~25mm; 4. The temperature between the channels is recommended to be kept at around 300 °C; 5. Before welding, the weldment must be cleaned of rust, oil, moisture and other impurities. Precautions:   Precautions for use: The wear-resistant solder layer should generally be surfacing 1 layer. Because the number of layers is too much, the surfacing layer becomes brittle due to too high hardness and is easily broken after collision. Due to the high hardness, the welding wire has a cracking sound during the welding, and a small crack occurs, which is a normal phenomenon and does not fall off, and does not affect the service life.   We are a real wear-resistant welding consumables production factory, with a complete production process and inspection process, to provide you with high quality and cost-effective wear-resistant welding consumables.
