This specification covers the basic requirements and corresponding test methods for forged, quenched, and tempered, alloy steel threaded eyebolts with improved toughness properties and that are chemically and metallurgically constituted to produce a low transition temperature to minimize brittle failure, intended primarily for low temperature applications. The eyebolts are furnished either as straight shank eyebolts (Type 1), or shoulder eyebolts (Type 2). Sampled specimens shall be tested, and conform accordingly to chemical (carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, and nickel), metallurgical (grain size, decarburization, and macrotech properties), and mechanical (Brinell hardness, tensile strength, breaking strength, proof load, impact strength, and bend strength) requirements.
1.1 This specification covers forged, quenched and tempered, alloy steel threaded eyebolts with improved toughness properties and intended primarily for low temperature applications. The eyebolts are chemically and metallurgically constituted to produce a low transition temperature to minimize brittle failure. Maximum thread size is 2.500 in. (63.50 mm).
1.2 The eyebolts are furnished in two types, as follows:
1.2.1 Type 1—Straight Shank Eyebolt.
1.2.2 Type 2—Shoulder Eyebolt.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.
1.4 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.
