The main characteristics of Alloy800HT superalloy are high temperature resistance and corrosion resistance.
Alloy800HT is a superalloy with the following main characteristics:
1. High temperature resistance: Alloy800HT has excellent high temperature resistance and can work for a long time at temperatures up to 1100. It has high thermal stability and oxidation resistance, and can withstand long-term use in high-temperature environments.
2. Corrosion resistance: Alloy800HT has good corrosion resistance and can effectively resist corrosion in acidic, alkaline and oxidizing environments. It has good corrosion resistance to a variety of corrosive media, including sulfuric acid, hydrochloric acid, nitric acid, and phosphoric acid.
3. High strength and good plasticity: Alloy800HT has high strength and good plasticity, and can be plastically deformed through hot processing (such as forging, hot rolling, etc.) to obtain the desired shape and size.
During the forging process of Alloy800HT, the following conditions need to be noted:
1. Forging temperature: The final forging temperature of Alloy800HT is usually between 1150-1200 to ensure that the material has good plasticity and deformation ability. Too high a temperature can cause the grain to grow and overheat, while too low a temperature can reduce plasticity.
2. Deformation degree: The appropriate degree of deformation can improve the strength and heat resistance of the material. In general, the degree of deformation of alloy 800ht should be controlled between 20-40% to obtain mechanical properties.
3. Cooling rate: After the forging is completed, the alloy 800HT needs to be properly cooled to enhance the mechanical properties and corrosion resistance of the material. Generally, air cooling or water quenching is used for cooling.
In conclusion, Alloy800HT is a high-temperature alloy material with the characteristics of high temperature resistance and corrosion resistance. In the forging process of Alloy800HT, it is necessary to control the forging temperature, deformation degree and cooling rate to ensure that the product has good performance.
