As the coating contains iron powder, it that highly efficient welding and can reduce welding layers.Application: It is suitable for welding carbon structure and low alloy steel structure, such as 16Mn, etc.ChemicalCompositionDepositedmetal(%)CMnSiSP≤0.12≤1.6≤0.75≤0.035≤0.040MechanicalPropertiesofDepositedmetalTestItemTensileStrengthós(Mpa)YieldStrengthós(Mpa)Elongationδ5(%)ImpactValue(J)-30°CGuranteed≥490≥400≥22≥27Tested520-580≥41024-3050-180Hydrogen diffuse of weld metal: ≤0.8ml/100g (glyceric method)X-ray Radiographic Inspection: 1 GradeSizes&RecommendedCurrent(ACorDC)Weldingroddiameter(mm)2.53.24.05.0weldingcurrent(A)90-120120-150170-200210-250NOTES: 1. Electrodes must be baked for 1 hour at 350°C before welding operation.2. It is essential to clean up rusty,oil scale,water and impurities on welding parts.3. Short arc operation is required when welding. Narrow weldingtrack is proper.4. Electrode is as positive pole when oprarion on DC.
