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
