| Abstract: | The flux-cored wires with different contents of carbon and chromium for submerged arc welding is designed, which composition rang of surfacing metal is 4.0%-6.5%C and 20%-40%Cr.Different analysis methods such as metallographic test, MPMA, the hardness test were utillized to analyse the influence for microstructures, hardness, qualities and distribution of primary carbide with different contents of C, Cr and Cr C. |
| Keywords: | high chromium cast iron flux-cored wires primary carbide |
