A193 Gr B7 Bolts: 

ASTM A193 Grade B7 is a standard specification for high tensile alloy steel bolting material for use in high temperature or high-pressure service and other special purpose applications. It covers material specification for bolting used in pressure vessel service, valves, flanges and fittings.

The minimum tensile strength for A193B7 is 125 ksi for diameters under 2-1/2”, and 115 ksi for 2-1/2” – 4” diameter. Hardness is probably the most significant difference between A193B7M & A193B7. The maximum hardness of astm a193 b7M is 235 HB or 99 HRB, while the maximum hardness of A193B7 is 321 HB or 35 HRC.

A193 Gr B7 Bolt Material:

For use in high temperature or high pressure service and other specialised applications, high tensile alloy steel bolting material must meet the standards of a193 gr b7. A standard specification that is appropriate for bolts used in pressure vessel service, valves, flanges, and fittings defines typical chemical composition, mechanical qualities, hardness requirement, preferential heat treatment, product labelling, certification, and other requirements. Both SI (Metric) and inch-pound units are defined in a193 b7.

chromium-molybdenum

Astm a193 grade b7 defines both SI (Metric) and inch-pound units. Grade B7 is a heat-treated chromium-molybdenum (Cr-Mo) alloy steel with minimum tensile strength requirement of 125 ksi, yield 105 ksi, and maximum hardness of 35HRC.
