What is heat treatment process used in Sa516 grad 70 plate

Question

Accepted Answer

The heat treatment process used in Sa516 grad 70 plate is called normalizing.

Normalizing involves heating the plate to a temperature above its critical range and then cooling it in still air.
This process helps to refine the grain structure and improve the mechanical properties of the plate.
It also relieves internal stresses and enhances the plate's resistance to brittle fracture.
Normalizing is typically performed after the plate has been formed and welded.
The specific temperature and cooling rate for normalizing may vary depending on the plate thickness and desired properties.

Accepted Answer

Heat treatment process is the series of operation involved the heat and cooling to form of solid material.
