Hikari Corporation

This time it is an introduction of annealing.

Do you know the word "namasu"?

I think that there are many people who imagine the thing that vegetables and fish are shredded and softened with vinegar.

 

It is a process that slowly cools the steel with heat applied.

The cooling method for cooling slowly is furnace cooling.

 

 

The steel becomes softer by annealing.

There are five types of annealing, but Hikari does "stress relieving" .

 

Next time, I would like to introduce this "stress relieving".
