A490-04a - Standard Specification for Structural Bolts, Alloy Steel, Heat Treated, 150 ksi Minimum Tensile Strength

This specification covers two types of quenched and tempered, alloy steel, heavy hex structural bolts having a tensile strength of 150 to 173 ksi. The bolts are furnished in sizes 1/2 to 1 ? in., inclusive. They are designated by type denoting chemical composition as follows:

Type 1 Medium carbon alloy steel  Type 2 Withdrawn in 2002  Type 3 Weathering steel

 

A489-04 - Standard Specification for Carbon Steel Lifting Eyes

This specification covers weldless forged, quenched, and tempered carbon steel threaded lifting eyes (formerly eyebolts) for overhead lifting. The specification includes two types denoting shank pattern and one style denoting shank length (both defined in ASME B 18.15) as follows:Type 1?Plain pattern (straight shank).Type 2?Shoulder pattern.Style B?Short length.

 

A449-04b - Standard Specification for Quenched and Tempered Steel Bolts and Studs

This specification covers the chemical and mechanical requirements for two types of quenched and tempered steel bolts and studs for general applications where high strength is required. The two types of bolts covered in this specification are: Type 1 ? Medium-carbon steel bolts and studs furnished in nominal diameters of 1/4 to 3 in., inclusive. Type 2 ? Low-carbon martensite or medium-carbon martensite steel bolts and studs furnished in nominal diameters of 1/4to 1 in., inclusive.

 

A394-04 - Standard Specification for Steel Transmission Tower Bolts, Zinc-Coated and Bare

This specification covers the chemical and mechanical requirements of hexagon and square-head zinc-coated steel bolts and atmospheric corrosion-resistant bolts, in nominal thread diameters of 1/2, 5/8, 3/4, 7/8 and 1 in. for use in the construction of transmission towers, substations, and similar steel structures. The various types of bolts covered in this specification are: Type 0 ? Zinc-coated bolts made of low or medium carbon steel.

Type 1 ? Zinc-coated bolts made of medium carbon steel, quenched and tempered.

Type 2 ? Zinc-coated bolts made from what is generally described as low-carbon martensite steel, quenched and tempered.

Type 3 ? Bare (uncoated), quenched and tempered bolts made of steel having atmospheric corrosion-resistance and weathering characteristics comparable to that of the steel covered in Specifications A 242/A 242M, A 588/A 588M, and A 709/A 709M. The atmospheric corrosion resistance of these steels is substantially better than that of carbon steel with or without copper addition (see 5.4). When properly exposed to the atmosphere, these steels can be used bare (uncoated) for many applications.

 

A354-04 - Standard Specification for Quenched and Tempered Alloy Steel Bolts, Studs, and Other Externally Threaded Fasteners

This specification covers the chemical and mechanical requirements of quenched and tempered alloy steel bolts, studs, and other externally threaded fasteners 4 in. and under in diameter for application at normal atmospheric temperatures, where high strength is required and for limited application at elevated temperature (Note 1). Any alloy steel capable of meeting the minimum mechanical and chemical properties set forth in this specification may be used. Two levels of bolting strength are covered, designated Grades BC and BD. Selection will depend upon design and the stresses and service for which the product is to be used.

 

A325M-04b - Standard Specification for Structural Bolts, Steel, Heat Treated 830 MPa Minimum Tensile Strength [Metric]

This specification covers two types of quenched and tempered, steel, metric heavy hex structural bolts having a minimum tensile strength of 830 MPa. The bolts are furnished in sizes M12 to M136 inclusive. They are designated by type denoting chemical composition as follows:

1.3.1 Type 1?Medium-carbon, carbon boron, medium carbon alloy, or alloy boron steel.

1.3.2 Type 2?Withdrawn in 2003.

1.3.3 Type 3?Weathering Steel.

1.4 This specification is applicable to metric heavy hex, structural bolts only.

 

A325-04b - Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength

This specification covers two types of quenched and tempered steel structural bolts having a minimum tensile strength of 120 ksi for sizes 1.0 in. and less and 105 ksi for sizes over 1.0 to 1? in., inclusive. The bolts are intended for use in structural connections. These connections are covered under the requirements of the Specification for Structural Joints Using ASTM A 325 or A 490 Bolts, approved by the Research Council on Structural Connections of the Engineering Foundation. The bolts are furnished in sizes ? to 1? in., inclusive. They are designated by type, denoting chemical composition as follows: Type Description Type 1 Medium carbon, carbon boron, or medium carbon alloy steel. Type 2 Withdrawn in November 1991. Type 3 Weathering steel.

 

A307-04 - Standard Specification for Carbon Steel Bolts and Studs, 60 000 PSI Tensile Strength

This specification covers the chemical and mechanical requirements of three grades of carbon steel bolts and studs in sizes 1/4 in. (6.35 mm) through 4 in. (104 mm). The fasteners are designated by "Grade" denoting tensile strength and intended use, as follows: Grade Description Grade A Bolts and studs having a minimum tensile strength of 60 ksi (414 MPa) and intended for general applications Grade B Bolts and studs having a tensile strength of 60 to 100 ksi (414 to 690 MPa) and intended for flanged joints in piping systems with cast iron flanges, and Grade C Nonheaded anchor bolts, either bent or straight, having properties conforming to Specification A 36/A 36M (tensile strength of 58 to 80 ksi (400 to 550 MPa)) and intended for structural anchorage purposes.

 

A31-04 - Standard Specification for Steel Rivets and Bars for Rivets, Pressure Vessels

This specification covers steel rivets for use in boilers and pressure vessels and steel bars for use in the manufacture of rivets.

 

E2368-04e1 - Standard Practice for Strain Controlled Thermomechanical Fatigue Testing

This practice covers the determination of thermomechanical fatigue (TMF) properties of materials under uniaxially loaded strain-controlled conditions. A "thermomechanical" fatigue cycle is here defined as a condition where uniform temperature and strain fields over the specimen gage section are simultaneously varied and independently controlled. This practice is intended to address TMF testing performed in support of such activities as materials research and development, mechanical design, process and quality control, product performance, and failure analysis. While this practice is specific to strain-controlled testing, many sections will provide useful information for force-controlled or stress-controlled TMF testing.
