Dear All

 

I need to know how can understand that ASTM A516 Gr.70 is normalized or not?

 

Somebody told me:

 "according to clause 5.3 of ASTM A516 standard (attached), when we apply charpy impact test on a material and it pass the impact test successfully, we can say the material is surly normalized but if the material can't pass the impact test, we shall apply metallographic test to understanding if the material is normalized.

 

And somebody said me:

"we have just 1 way to know that is the material normalized or not. And its metallographic test."
