3、ent of Defense.1. Scope Scope*1.1 This specification covers carbon, low-alloy, high-strength low-alloy, and alloy steel hot-rolled floor plates for flooring,stairways, transportation equipment, and general structural purposes. While it is generally provided in the as-rolled condition, floorplate als
4、o may be provided in the heat-treated condition, depending on the material specification. Rolled floor plates have raisedfigures at regular intervals on one surface of the plate.1.2 Floor plate is available in dimensions that meet the classification size limits for sheet, heavy thickness sheet coil,
5、 or plate.Maximum thickness for product 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 useor service will be utilized. See Appendix X3 of Specification A6/A6M for informatio
6、n on weldability.1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in eachsystem are not exact equivalents; therefore, each system is to be used independently of the other, without combining values.2. Referenced Documents2.1 AST
