In 2016 the specification A325 was withdrawn by ASTM and was replaced by ASTM F3125 with A325 as one of the six Grades of F3125.
F3125 Grade A325 is a Heavy Hex Head Style Bolt with a minimum Tensile Strength of 120 ksi. and can come in one of two types (Type 1 or Type 3). We currently stock only Type 1 so this information will be limited to a discussion of that type.
Chemical Requirements (TYPE 1)
