Hi,
I was just looking at AMS2431/6 and it says that the hardness of the glassbeads under this spec should be between HRC48-52. This is the same for for normal hardness steel shots under AMS2431/1. Did I interpret this incorrectly? I find it kind of puzzling: how can glass beads be of same hardness as steel shots? I would think that glassbeads definitely fractures much faster than steel shots.
