This time, I will talk about heat treatment in Hikari.

It is called "stress relieving".

 

It is stressful when people also have a hard time.

Steel is stressed by being pulled.

Think of this as "stress.".

 

When stress is too stressful, people lose their health.

Steel is the same. Break.

That's where we 'relieving' stress.

Stress relieving is heat treatment that relieves the stress of steel.

It's like a person taking a bath and getting tired.

 

In the case of steel, heat at 500 to 600 °C.

Then, it recovers so that it can endure the stress such as the pull again.
