Detail
A193 B7M has a minimum tensile strength of 100 KSI for diameters under 4. The minimum tensile strength for A193B7 is 125 KSI for diameters under 2-1/2, and 115 KSI for 2-1/2 diameter. Hardness is probably the most significant difference between A193B7M & A193B7. The maximum hardness of ASTM A193B7M is 235 HB or 99 HRB, while the maximum hardness of A193 B7 is 321 HB or 35 HRC. The most notable difference from a manufacturing perspective is that when providing A193B7M bolts, every individual bolt or stud in the lot must be hardness tested. A193B7M fasteners will also require a different grade of heavy hex nut than A193B7, which would be ASTM A194 Grade 2HM.
