With ASTM A325 having two types available, it is occasionally asked which type is normally supplied or assumed on a request for quote, if the description does not specify. The answer is either one. Per the ASTM specification, if an A325 type is not specified, either type 1 or type 3 may be furnished at the supplier’s option. If it is a quote received, the description should specify which type of A325 they are and if it is was an order received, it should have material test reports specifying which type was supplied.
