Nickel-based self-fluxing alloy powder

       Description: Description: Ni20B is a nickel-iron-chromium-borosilicate alloy powder developed for glass molds on the basis of DG.Ni 20A. The performance is similar to Ni 20A, but the price is slightly lower. It is suitable for the oxygen-acetylene flame spray welding process. It is a spray welding alloy powder developed according to the characteristics of glass molds for repair and pre-spray treatment. Powder chemical composition (Wt%) C Cr Si B Fe Ni <0.1 2.0-5.0 2.0 -2.8 1.0 -1.3 <15.0 The remaining powder melting temperature: 1050-1150 ℃ Spray welding layer hardness: HRC18-22 Note: 1. Please Weld in strict accordance with the requirements of the oxygen-acetylene flame spray welding process. 2. When using medium and small spray guns, -150 mesh powder should be used, 　　　　　　　 when using large spray guns, it is better to use -150/+320 mesh powder. 　　　　　　 3. If the alloy powder has moisture absorption, it should be dried before use (120 ℃, heat preservation for 1 hour).
