Manufacturing Process of Hastelloy X Plate
Melting and Alloying
- Vacuum Induction Melting (VIM) or Electro-Slag Remelting (ESR) processes are used to melt the raw materials and blend them into a homogeneous alloy.
- These processes ensure that the alloy composition is precise and free from contaminants.
Casting
- After melting, the alloy is cast into ingots.
- Casting techniques are carefully controlled to achieve the desired shape and size, while minimizing internal defects such as porosity and inclusions.
Hot Working
- Forging: The ingots are heated to an appropriate temperature and then forged to shape. Forging improves the alloy’s density and mechanical properties.
- Rolling: The forged material is then rolled into plates of the desired thickness and width. Multiple passes of rolling may be required to achieve the final dimensions.
Heat Treatment
- Annealing: The plates are heated to a specific temperature and then cooled slowly to relieve stresses and improve ductility.
- Solution Annealing: This step involves heating the plates to a temperature above the solidus line, holding for a period, and then rapidly cooling to fix the alloy composition in a homogeneous solid solution.
- Aging: After solution annealing, the plates may be aged at a lower temperature to precipitate strengthening phases, enhancing mechanical properties.
Surface Finishing
- Shot Blasting: The plates may undergo shot blasting to remove surface imperfections and improve surface finish.
- Pickling: Chemical pickling can be used to remove oxide scales and other contaminants from the surface.
Inspection and Testing
- Chemical Analysis: To ensure the alloy composition meets specifications.
- Mechanical Testing: Tensile tests, impact tests, and hardness tests are conducted to evaluate the mechanical properties.
- Non-Destructive Testing (NDT): Methods such as ultrasonic testing (UT) and radiographic testing (RT) are used to detect internal defects.
Final Machining and Fabrication
- The plates may undergo final machining operations such as cutting, drilling, and threading to meet specific part requirements.
- Fabrication processes such as welding and assembly may also be involved in producing final components or assemblies.
