1. Scope
1.1 This specification 2 covers high-strength quenched and tempered low-alloy steel forged parts for pressure vessels. The maximum thickness of forgings under this specification shall be 1 1 ⁄ 2 in. [38 mm] for Grade A, and 4 in. [100 mm] for Grades E and F. N OTE 1—These grades are similar to corresponding grades in Specifi- cation A517/A517M. 1.2 Although no provision is made for supplementary re- quirements in this standard, the supplementary requirements in Specification A788/A788M may be considered by the pur- chaser. 1.3 Welding technique is of fundamental importance and it is presupposed that welding procedures will be in accordance with approved methods for the class of material used. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.5 Unless the order specifies the applicable “M” specifica- tion designation, the material shall be furnished to the inch- pound units. 1.6 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Ordering Information and General Requirements
3.1 In addition to the ordering information required by Specification A788/A788M, the purchaser shall include with the inquiry and order the following information: 3.1.1 A detailed drawing, a sketch, or written description of the forging. 3.1.2 The charpy impact test temperature if a test tempera- ture lower than 32 °F [0 °C] is required. 3.1.3 Additional heat treatment cycles to be applied to the mechanical test specimens following removal from the heat- treated forging or special forged test block. 3.1.4 Required supplementary requirement(s) from Specifi- cation A788/A788M. 3.2 Material supplied to this specification shall conform to the requirements of Specification A788/A788M, which out- lines additional ordering information, manufacturing requirements, testing and retesting methods and procedures, marking, certification, product analysis variations, and addi- tional supplementary requirements. Failure to comply with the requirements of Specification A788/A788M constitutes non- conformance with this specification.3.3 If the requirements of this specification are in conflict with the requirements of Specification A788/A788M, the requirements of this specification shall prevail.
4. Materials and Manufacture
4.1 Melting Process—The steel shall be made in accordance with the Melting Process Section of Specification A788/ A788M. 4.2 Grain Size—The steel shall be fully killed, fine grained (ASTM No. 5 or finer), as determined in accordance with Test Methods E112, Plate IV. 4.3 Discard—Sufficient discard shall be made from each ingot to ensure freedom from piping and excessive segregation. 4.4 The finished product shall be a hot-worked forging as defined by Specification A788/A788M, and shall be forged as close as practicable to the finished shape and size.
5. Heat Treatment
5.1 After forging and before reheating, the forgings shall be cooled to provide substantially complete transformation of austenite. Heat treatment for properties shall consist of heating the forgings to not less than 1650 °F [900 °C], quenching in a liquid medium, and tempering at 1150 °F [620 °C] minimum, with a holding time of 1 h/in. [1 h/25 mm] minimum, but in no case less than 1 ⁄ 2 h.
6. Chemical Requirements
6.1 Heat Analysis—The heat analysis obtained from sam- pling in accordance with Specification A788/A788M shall comply with Table 1. 6.2 Product Analysis—The purchaser may use the product analysis provision of Specification A788/A788M to obtain a product analysis from a forging representing each heat or multiple heat.
