Re: [MW:29075] grain size requirements for 321H stainless steel

Lower grain size (e.g. 6, 5, 4 and so on) are coarser

Thanks & Regards,

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
