Material Properties
The post-weld material is a molybdenum-containing compound carbide alloy exhibiting excellent wear resistance, moderate impact resistance, and strong spalling resistance. It is unsuitable for flame cutting and cannot be machined, with minute stress cracks present on the surface. | |
1. Microstructure: Austenitic chromium-manganese steel; Alloy type: C-Cr-Mn-Fe-Mo | 2. Machinability: Only grinding is supported |
3. Cutting Performance: Flame cutting is not supported | 4. Cladding thickness: Supports multi-layer cladding thicknesses, with cladding thicknesses achievable up to 30–50 mm. |
Application
Highly suitable for hardfacing components subjected to high wear and general impact. Examples include wear-resistant layers for coal mill grinding rollers and grinding discs. Operating temperature range not exceeding 500°C.
