ASTM A786-15(R2021) pdf free download.Standard Specification for Hot-Rolled Carbon, Low-Alloy, High-Strength Low-Alloy, and Alloy Steel Floor Plates
1. 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, floor plate also may be provided in the heat-treated condition, depending on the material specification. Rolled floor plates have raised figures 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, 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 use or service will be utilized. See Appendix X3 of Specifica- tion A6/A6M for information 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 each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and the values from the two systems shall not be combined. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
4. Surface Pattern
4.1 Individual floor plate patterns are unique to each manu- facturer and are not identical in dimension or appearance to patterns manufactured by other manufacturers, although there may be a close resemblance. Typical patterns are shown in 1. Manufacturers generally produce only one of the patterns shown. 4.2 Pattern size and shape are not addressed in this specifi- cation due to the differences in individual manufacturer’s patterns and production methods. Where a need for these attributes exists, purchasers should consult the manufacturer. 4.3 Minimum pattern height shall be 0.020 in. [0.5 mm] for material with a base thickness equal to or greater than 0.070 in. [1.8 mm]. The minimum pattern height shall be 0.015 in. [0.4 mm] for material with a base thickness less than 0.070 in. [1.8 mm].
5. Ordering Information
5.1 Information items to be considered, if appropriate, for inclusion in purchase orders are as follows: 5.1.1 Quantity (weight [mass] or number of pieces), 5.1.2 ASTM designation and year of issue, 5.1.3 Chemical composition limits or ASTM material des- ignation and grade (if applicable) and year of issue (if neither is specified, the product will be supplied 0.33 % maximum carbon, by heat analysis, and without specified mechanical properties). 5.1.4 Dimensions (decimal thickness, width, and either cut length of plate or coil size and weight [mass] requirements as applicable), 5.1.5 Condition, if other than as-rolled, 5.1.6 Product form (plate, sheet, or coil) and pattern from Fig. 1. As indicated in 4.2, ifspecific pattern attributes, or some alternative pattern, are desired, the purchaser will need to consult with the manufacturer, 5.1.7 Product analysis (see 9.3), 5.1.8 Copper-bearing steel, if required (see 9.4).
6. General Requirements
6.1 Except as otherwise specified, product furnished under this specification as plate shall conform to the applicable requirements of Specification A6/A6M.
9. Chemical Composition Limits
9.1 Specified to Chemical Composition Limits Only—The heat analysis shall conform to the chemical limits specified in the purchase order. 9.2 Specified to an ASTM Specification—The heat analysis shall conform to the chemical requirements listed in the applicable specification. 9.3 Where specified in the purchase order, product analyses shall be performed at the frequency specified in the purchase order, and such analyses shall conform to the applicable specified limits for heat analysis, subject to the permitted variations in product analysis in Specification A6/A6M. 9.4 If copper-bearing is specified in the purchase order, the material shall contain at least 0.20 % copper, by heat analysis.
