Dec 9, 2003 #2 RXH Mechanical Aug 27, 2002 39 0 0 US As far as I can tell from ASTM A194, the chemical compositions are the same but the manufacturing process and heat treatment is different. This results in hardness range requirements of Brinell Hardness 126 - 300 for 8M and 126 - 192 for 8MA. Upvote 0 Downvote
