HEAT TREATMENT
Heat Treatment
Heat Treatment is the process of heating the metal without allowing it to reach a melting point, or melting, and then cooling the metal in a controlled manner to select the desired mechanical properties. It can heat up to a maximum temperature to 1200° Celsius. It also can be used in almost all types of plumbing, headers, branches, flanges, valves and widely used for carbon steel and alloy steel.
Types of Heat Treatment:
1) Post Weld Heat Treatment (PWHT)
2) Pre-Heating
3) Post Heating
4) Normalizing
5) Quenching
Advantages of applying Heat Treatment:
1) Reduces the risk of brittle fractures.
2) Increases the ductility of material.
3) Permeable hydrogen removal (To prevent hydrogen cracking)
4) Better metallurgical structure.
5) Material becomes more flexible.
