welding-alloys.com 41 Mechanical fatigue Thermal fatigue Hot oxidation Corrosion Cutting Work hardening Machining Description and applications uu uu uu uu u u u Low carbon cobalt base, easy to apply due to its low cracking tendency. Highly resistant to temperature and metal-to-metal wear. Maintains a good level of hardness at high temperatures. Applications: extrusion dies, nozzles, pump shafts. u uuuuuuuu u uu Low carbon cobalt base, with low cracking tendency. Ideal choice for resistance to multiple combinations of stress, such as corrosion and cavitation. Maintains a good level of hardness at high temperatures. Can be work hardened and polished. Low coefficient of friction. Applications: industrial valve work, forging dies and hot shearing blades. uu uu uu uu u u Combines all the outstanding properties of cobalt based alloys, including abrasion and erosion resistance. Medium hardness deposit with good machinability. Tailored compositions are also possible by adjusting the carbon content. A lower carbon content, and therefore lower cracking tendency, facilitates machining. A higher carbon content allows the required hardness to be obtained on low alloy steels from the first layer. Applications: hot shearing tools, petrochemical and industrial valves, valves and valve seats of marine engines, pump sleeves and shafts. uu uu uu uu uu u u uuuuuu u u u uuuuuu u Good resistance to mineral abrasion due to its high hardness. Particularly suited for use on cutting tools. Applications: wood cutting tools, screw conveyors and augers for rubber and plastics, saw blades. u u u u u u u Highest hardness of the cobalt based alloy range, offering excellent resistance to abrasion and corrosion. Self polishing, promotes scratch free sliding of abrasive materials. Applications: rubber kneaders, mixer blades, plastic extrusion screws. Back to contents page
