Influence of the chromium, molybdenum and carbon relationship on structure and properties of deposit metal in the Fe-Cr-Mo-C system

摘要

The Fe-Cr-Mo-C system components influence on structural-phase composition, tendency to cracks formation, heat-resistance and high-temperature of metal deposited by electric arc and electric slag methods using flux-cored wire is considered. Optimal relationship between carbide-forming components and carbon is determined. At such relationship deposited method has sufficient properties level under hot press-dies operation conditions.
