Standard Specification for Rolled Steel Floor Plates
|Publication Date:||10 March 2000|
|ICS Code (Flat steel products and semi-products):||77.140.50|
1.1 This specification covers carbon, high-strength low-alloy, and alloy steel rolled floor plates for flooring, stairways, transportation equipment, and for general structural purposes. While it is generally provided in the as-rolled condition, it may also be provided in the heat-treated condition (see Appendix Table X1.1). Rolled floor plates have raised figures at regular intervals on one surface of the plate.
1.1.1 Carbon steel may be specified to chemical composition limits, the maximum carbon of which should not exceed 0.33 % or, an ASTM material specification with yield point or yield strength and tensile strength may be specified (see Appendix Table X1.1).
1.2 Rolled floor plate is customarily available in a limited number of gage numbers or thicknesses. Standard gage numbers and thicknesses are shown in Table 1. The maximum thickness to be delivered under this specification is 1 in. [25 mm].
1.3 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 A 6/A 6M for information on weldability.
1.4 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 noncomformance with the specification.
