2020-3-31 · Sand that is too coarse (lower GFN) can create high permeability and lead to problems with metal penetration, rough surface finish, burn-in and burn-on. The AFS Grain Fineness Number (AFS-GFN) is one means of measuring the grain fineness of a sand system. GFN is a measure of the average size of the particles (or grains) in a sand sample.
