ASTM A354 grade bd Bolts

ASTM A354 - 17e1

ASTM A354 is a Standard Specification for Quenched and Tempered Alloy Steel Bolts, Studs, and Other Externally Threaded Fasteners

ASTM A354 specification covers the chemical and mechanical requirements of quenched and tempered alloy steel bolts, studs, and other externally threaded fasteners. All fasteners shall be made from alloy steel conforming to the chemical composition requirements. 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. Hardness, tensile strength, yield strength, elongation, and area reduction shall be tested to meet the requirements prescribed.ASTM A354 Bolts

ASTM A354 bolts can be used for many different applications that include fastening wood, steel, and other construction materials for projects such as docks, bridges, highway structures, and buildings. ASTM A354 Hex Bolts and ASTM A354 Hex Head Bolts is some of the toughest fasteners. These ASME SA354 sturdy fasteners are used to connect heavy materials.

ASTM A354 Grades

ASTM A354 covers two different strength levels, grade BC and grade BD

Grades
A354 BD Higher in strength than A354 grade BC and equal in strength to ASTM A490 bolts. The A354 BD specification has no restrictions on configuration. A354 BD should be considered for anchor bolts, threaded rods, other styles of headed bolts, and bolts larger than 1-1/2" diameter where properties similar to A490 are needed. A354 grade BD does not require a magnetic particle test.
A354 BC Lower in strength than grade BD.

1. Scope

1.1 ASTM A354 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 mechanical and chemical properties set forth in this specification may be used.

NOTE 1: For bolts, studs, or other externally threaded fasteners, to be used at elevated temperatures, refer to Specification A193/A193M.

1.2 Two strength levels 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.

NOTE 2: Quenched and tempered alloy steel bolts for structural steel joints up through 11/2 in. in diameter are covered in Specification F3125/F3125M. For fastener diameter sizes above 1 1/2 in., Grade BC may be considered for structural steel bolting where tensile strength above 120 ksi is necessary and Grade BD may be considered for structural steel bolting where tensile strength above 150 ksi is necessary. In this event, additional requirements of Specification F3125/F3125M, such as head size, lubricant, and magnetic particle inspection, should be carefully considered.

1.3 Nuts are covered in Specification A563. Unless otherwise specified, the grade and style of nut for each grade of fastener shall be as follows:

Available standard: DIN 934, ISO 4033, ISO 4032, DIN 935,DIN 936, ASME B18.2.2, ASME B18.2.4.6M, DIN 976, DIN 975, DIN 2510, DIN 939, DIN 940, DIN 938
