Dear kannayeram,

Is there any hand book or reference standard available for those quantities of Si and Al you mentioned?

 

Regards

Dear experts,

I have a steel which marked as A516 Gr.70. I checked the metallugraphic structure and the microstructure is same as both semi and fully killed steel. (In SA516 it is defined that the quality grade shall be fully killed).

Now my question is:

 

How can I find that this steel is fully killed or semi killed?

Can anyone introduce any reference standard or handbook to differs between these two quality grades and also a test procedure for that purpose?

 

Regards
