ASTM A193 is a specification that “covers alloy and stainless steel bolting material for pressure vessels, valves, flanges, and fittings for high temperature or high-pressure service, or other special purpose applications.” Since A193B7 is commonly available as a heavy hex bolt or fully threaded stud, it is familiar to engineers and therefore may be the grade specified for an anchor rods. This is usually due to the strength of the material. Although there isn’t anything prohibiting anchor bolts to be made to the A193 Grade B7 specification, this grade is not intended for anchor bolt use. A grade that should be considered is ASTM F1554 Grade 105. ASTM F1554 Grade 105 is a specification specifically developed for anchor bolts and possesses virtually identical chemical and physical properties.
