ASTM A1099 Specification

Forgings, Fasteners, Boltings, Stud Bolts, Screws, Nuts

Scope

ASTM A1099 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:
API 6A Specification for Wellhead and Christmas Tree Equipment and Errata,
API RP 6AR Recommended Practice for Repair and Remanufacture of Wellhead and Christmas Tree Equipment,
API 16A Specification for Drill-Through Equipment,
API 16R Specification for Marine Drilling Riser Couplings,
API 17D Specification for Subsea Wellhead and Tree Equipment and Errata,
API 8C Specification for Drilling and Production Hoisting Equipment.
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.
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.
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.
ASTM A1099 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.
