Product details:
RD-389
——————————————————————————————————————————————
Surfacing wire for composite wear-resistant steel plate
Material Characteristics
| The post-welding material has high anti-wear performance, the surfacing material contains initial carbide; welding spatter is small, the post-welding surface is flat and beautiful, the welding efficiency is high, and the recovery rate of welding wire is high. | |
| 1.Microstructure: Austenitic chromium-manganese steel；Alloy Type：C-Cr-Fe | 2.Processing performance: only support sanding |
| 3.Cutting performance: does not support flame cutting | 4.Surfacing thickness: supports multi-layer surfacing，thickness up to 30mm |
Applications
| Composite wear-resistant steel plate / wear-resistant pipe special wire, can also be used for surfacing chute, screen plate, conveying channel, lining plate and other parts that need to do anti-wear treatment. The application temperature range does not exceed 450℃. |

Welding Precautions
1. Use RD-389 wire without inert gas and take care to control the current and voltage according to the recommended overlay welding parameters. 2. The overlays will have normal fine stress relief cracks, which will help to prevent the occurrence of large-scale spalling of the overlays. 3. Oscillating and linear welding can be welded, can be surfaced multi-layer, surfacing alloy layer performance and surfacing dilution rate. |
