(Specification)Standard Specification for Modified Alloy Steel Forgings, Forged Bar, and Rolled Bar Commonly Used in Oil and Gas Pressure Vessels
Standard Specification for Modified Alloy Steel Forgings, Forged Bar, and Rolled Bar Commonly Used in Oil and Gas Pressure Vessels
ABSTRACT
This specification covers modified high-strength alloy steel forgings and rolled and forged bar commonly used in oil and gas pressure vessels and oilfield equipment. Oil and gas product specifications for which this material is intended include, but are not limited to, the following: specification for wellhead and Christmas tree equipment and errata, recommended practice for repair and remanufacture of wellhead and Christmas tree equipment, specification for drill-through equipment, specification for marine drilling riser couplings, specification for subsea wellhead and tree equipment and errata, and specification for drilling and production hoisting equipment.
This specification covers requirements for melting, hot working, heat treatment, chemical composition, mechanical properties and testing, rework and retreatment, inspection, certification, product marking, and workmanship, finish, and appearance, as well as metallurgical requirements and nondestructive examination (NDE) requirements.
SCOPE
1.1 This specification covers modified high-strength alloy steel forgings and rolled and forged bar for oil and gas pressure vessels and oilfield equipment. See Appendix X1. Oil and gas product specifications for which this material is intended include, but are not limited to, the following:
1.1.1 API 6A Specification for Wellhead and Christmas Tree Equipment and Errata,
1.1.2 API RP 6AR Recommended Practice for Repair and Remanufacture of Wellhead and Christmas Tree Equipment,
1.1.3 API 16A Specification for Drill-Through Equipment,
1.1.4 API 16R Specification for Marine Drilling Riser Couplings,
1.1.5 API 17D Specification for Subsea Wellhead and Tree Equipment and Errata,
1.1.6 API 8C Specification for Drilling and Production Hoisting Equipment.
1.2 Supplementary requirements are provided for use when additional testing or inspection is desired. These shall apply only when specified individually by the purchaser in the order.
1.3 In the case of conflict between a requirement of this specification and a requirement of referenced general specifications, this specification takes precedence. In the case of conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order or contract, the purchase order or contract take precedence. The purchase order or contract requirements shall not take precedence if they, in any way, violate the requirements of the product specification or this specification, for example, by the waiving of a test requirement or by making a test requirement less stringent. In the case of conflict in terminology between API standards and Terminology A941, Terminology A941 definitions shall be applied.
1.4 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
1.5 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
