D132 in line with GB / T 984 EDPCrMo-A2-03 Description: D132 titanium calcium type coating of CrMo-type surfacing electrode. AC and DC, when the welding arc stability, easy slag removal. Uses: Used by the wear of low carbon steel, medium carbon steel and low alloy steel parts surface, especially suitable for welding and repair of mining machinery and agricultural machinery wear parts. Deposited metal chemical composition (%) C Cr Mo guaranteed ≤0.50 ≤3.00 ≤1.50 Example value 0.28 1.96 0.32 Surfacing layer hardness: HRC≥30 Reference current (AC, DC) electrode diameter (mm) f3.2 f4.0 f5.0 welding current (A) 80 ~ 130 110 ~ 180 150 ~ 240 Note: 1. Welding electrodes shall be subject to about 150 ℃ baking 1h. 2. In large parts before welding should be properly preheated to about 300 ℃, rust and oil and welding parts of the surface to be cleaned.
