Heat Treatment
After forging and before reheating for heat treatment, the forgings in accordance with ASTM A266 shall be cooled in such a manner as to prevent injury and to accomplish transformation. All the ASTM A266 forgings shall be heat treated by one of the four processes: annealing, normalizing, normalizing and tempering, or liquid quenching and tempering. When tempering is performed, it shall be at a subcritical temperature, but no less than 1100°F [595°C].
"N" refers to "Normalization", which is a heat treatment process used to enhance the mechanical properties of the material, such as its strength and toughness. During normalization, the material is heated to a specific temperature, typically above the transformation range, and then cooled in air. This process helps to refine the grain structure, improve uniformity, and relieve internal stresses in the material.
Some common applications of tubesheets:
1. Heat Exchangers
2. Boilers
3. Condensers
4. Reactors
5. Oil and Gas Industry
6. Air Conditioning and Refrigeration
7. Pressure Vessels
