Alloy800H austenitic heat-resistant alloy material properties and forging conditions.
Alloy 800H is an austenitic heat-resistant alloy material with the following properties:
1. High temperature strength: Alloy 800H has excellent high temperature strength and can maintain good mechanical properties in high temperature environment. It has high tensile strength and yield strength and can withstand loads under high temperature and stress conditions.
2. Good creep resistance: Alloy 800H has creep resistance, which can maintain a stable shape and size for a long time at high temperatures. This makes it ideal for long-term use in high-temperature environments, such as oil refining, chemical, heat treatment and high-temperature heating equipment.
3. Oxidation resistance: Alloy 800H has good oxidation resistance and can resist high temperature oxidation and corrosion. It is able to form a dense layer of chromium oxide, which effectively prevents the oxidation and corrosion of the metal at high temperatures.
4. Good welding performance: Alloy 800H has good welding performance and can be connected by conventional welding methods. Its welded joints have good strength and corrosion resistance, and can meet the requirements of high temperature and corrosive environments.
Regarding the forging conditions of Alloy 800H, it mainly includes the degree of deformation and the final forging temperature
1. Deformation degree: In the forging process, the appropriate degree of deformation should be selected according to the specific application requirements and geometric shape. In general, the right degree of deformation can improve the mechanical properties and creep resistance of the material.
2. Final forging temperature: The final forging temperature of Alloy 800h should be selected according to the thermal deformation characteristics of the material and the requirements of the forging process. Generally speaking, the final forging temperature should be controlled within the solution temperature range of the alloy to ensure that the material has good structure and properties.
It is important to note that the specific forging conditions need to be selected and optimized according to the specific grade and application requirements of the alloy. Before proceeding with a forging operation, it is advisable to consult with a material dealer or engineer to ensure the forging results and properties obtained.
