Metrode Cobstel-8 description: This low carbon cobalt base type combines good high temperature strength with high ductility. The improved ductility provides better resistance to weld cracking than the high carbon types. It has high resistance to corrosion, oxidation and sulphidation; good resistance to cavitation-erosion and resists thermal shock better than high carbon types. Galling resistance is inferior to high carbon types but bed-in properties are better. It is used to surface valves and valve seats, hot shear blades, hot work dies, ingot tong ends and equipment for handling hot steel. Used for cat cracker slide valves in petrochemical industry.
