ASTM A710/A710M-00

Standard Specification for Age-Hardening Low-Carbon Nickel-Copper-Chromium-Molybdenum-Columbium Alloy Structural Steel Plates

SCOPE
1.1 This specification covers low-carbon age-hardening nickel - copper - chromium - molybdenum - columbium alloy steel plates for general applications.
1.2 One grade with three different conditions is provided as follows:Grade and ClassConditionGrade A, Class 1 as-rolled and precipitation heat treatedGrade A, Class 2normalized and precipitation heat treatedGrade A, Class 3 quenched and precipitation heat treated
1.3 Grade A provides minimum yield strength levels ranging from 50 to 85 ksi [345 to 585 MPa], depending on thickness and condition.
1.4 Grade A, Class 1, plates are limited to a maximum thickness of 3/4 in. [20 mm]. The maximum thickness of Grade A, Classes 2 and 3, is limited only by the capacity of the composition to meet the specified mechanical property requirements; however, current practice normally limits the maximum thickness to 8 in. [200 mm].
1.5 Mandatory notch toughness requirements are specified for Grade A, Class 1.
1.6 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 of Specification A6/A6M for information on weldability.
1.7 The values stated in either inch-pound units or SI units are to be regarded separately 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 the specification.
