1.1 This specification covers structural quality alloy steel plates.
1.2 The plates are usually specified to chemical composition requirements, but tensile properties may also be specified.
1.2.1 When tensile properties are required, the specific requirements must be compatible with the chemical composition, condition, and plate thickness.
1.3 The plates are available in the following four conditions:
1.3.1 Condition AR8212;As rolled (hot rolled),
1.3.2 Condition A8212;Annealed,
1.3.3 Condition N8212;Normalized, and
1.3.4 Condition NT8212;Normalized and tempered.
1.4 The plates are available in the following three forms:
1.4.1 Form I8212;Rectangular,
1.4.2 Form II8212;Circular and semi-circular, and
1.4.3 Form III8212;Sketch, including rings.
1.5 The plates are available in the following five edge categories:
1.5.1 Edge 18212;Mill edge,
1.5.2 Edge 28212;Universal mill edge,
1.5.3 Edge 38212;Sheared edge,
1.5.4 Edge 48212;Gas cut edge, and
1.5.5 Edge 58212;Special cut edge.
1.6 The plates are available in the following seven finishes:
1.6.1 Finish 18212;As rolled (hot rolled),
1.6.2 Finish 28212;Blast cleaned,
1.6.3 Finish 38212;Blast cleaned and oiled,
1.6.4 Finish 48212;Pickled,
1.6.5 Finish 58212;Pickled and oiled,
1.6.6 Finish 68212;Painted, one prime coat, and
1.6.7 Finish 78212;Painted, one prime coat and one finish coat.
1.6.8 The plates are usually specified to have Finish 1.
1.7 Supplementary requirements are provided for additional requirements that may be specified on the order.
1.8 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.
1.9 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
