| RD-635 is a submerged arc self-protection wear-resistant flux-cored wire with good overlay performance, beautiful molding after welding, high strength, high hardness, good wear resistance and long service life. The hardness will increase after heat treatment (900℃, 16min, air cooling) of the material after welding. | |
| 1.Microstructure: Iron-based high-carbon, high-chromium wear-resistant alloys；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，Overlay thicknesses up to 4-8 mm |

1. When using RD-635 wire, do not use inert gas, and take care to control the current and voltage according to the recommended overlay welding parameters. 2. The overlay layer will have normal fine stress relief cracks, which will help to prevent the occurrence of large-scale spalling of the overlay layer. 3. Before surfacing, please pay attention to removing ash, oil, rust and corrosion in the area to be welded. 4. Oscillating and linear welding are available, can be overlaid with multiple layers, the performance of the alloy layer is related to the dilution rate of the overlaid welding. 5. Preheating can reduce stress cracks. |
