Re: [MW:29081] grain size requirements for 321H stainless steel

This number is related to the Number of grains in an specific area.

higher number of grains means they are smaller grains or fine grain.

Dear all

Please advise your views on below query:

ASTM A182 10.1.2 Grades F 321H, F 347H, and F 348H shall have a

grain size of ASTM No. 7 or coarser.

What does it stand for coarser? 

Does it mean a higher ASTM grain size no (e.g. 8, 9 and so on) or lower ASTM grain size no. (e.g. 6, 5, 4 and so on)?

Thanks & regards

Sandeep
