1.Compose.
The composition of UMCO-50 mainly includes chromium (Cr), cobalt (Co), molybdenum (Mo) and iron (Fe). Among them, cobalt is its basic element, which is in a high proportion, and the right amount of other elements is added to enhance its properties.
2.Characteristic.
1) Heat resistance: UMCO-50 has excellent high temperature resistance, can maintain stable mechanical properties and chemical properties in high temperature environment, and is suitable for high temperature working environment.
2) Corrosion resistance: UMCO-50 can also show good corrosion resistance at high temperatures, and can resist the erosion of corrosive media such as acids and alkalis.
3) Mechanical properties: The alloy has high strength and hardness, can withstand certain mechanical loads, and has good plasticity and machinability.
4) Toughness: UMCO-50 has good toughness and ductility, which helps to reduce stress concentration and cracking in high temperature environments.
3. Usefulness. Residue vaporizer forging nozzles, high temperature and high pressure valves, internal combustion engine exhaust valves, sealing surfaces, chain saw guide plates, plasma spray welding, high temperature molds, steam turbine blades, furnace parts, etc.
