Standard Specification for Normalized High-Strength Low-Alloy Structural Steel Plates

ABSTRACT
This specification covers normalized high-strength low-alloy structural steel plates for welded, riveted, or bolted construction. This material is suited for low ambient temperatures where the desired notch toughness is better than that expected in as-rolled materials of comparable strength level. The material shall have fine austenitic grain size and shall be normalized by heat treatment. Its chemical composition shall be determined by heat analysis. Tension tests shall also be done.
SCOPE
1.1 This specification covers normalized high-strength low-alloy structural steel plates for welded, riveted, or bolted construction.
1.2 This material is particularly suited for service at low ambient temperatures of 50F [45C] and higher where notch toughness better than that expected in as-rolled material of a comparable strength level is desired.
1.3 Four grades, designated Grades A, C, D, and E (essentially former Specification A 633 without a grade designation) are covered by this specification. Grade A provides a minimum yield point of 42 ksi [290 MPa] in thicknesses through 4 in. [100 mm], inclusive. Grades C and D provide a minimum yield point of 50 ksi [345 MPa] in thicknesses up to 2.50 in. [65 mm], inclusive and 46.0 ksi [315 MPa] in thicknesses over 2.50 in. to 4.0 in. [65 to 100 mm], inclusive. Grade E provides a minimum yield point of 60 ksi [415 MPa] in thicknesses up to 4.0 in. [100 mm], inclusive and 55 ksi [380 MPa] in thicknesses over 4 in. to 6 in. [100 to 150 mm], inclusive.
1.4 Current practice normally limits plates furnished under this specification to the maximum thicknesses shown in 1.3. The individual manufacturer should be consulted on size limitations for other product forms.
1.5 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 no id found of Specification A 6/A 6M for information on weldability.
1.6 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
