1、Designation: A506 12A506 16Standard Specification forAlloy and Structural Alloy Steel, Sheet and Strip, Hot-Rolledand Cold-Rolled1This standard is issued under the fixed designation A506; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revis
2、ion, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specifica
3、tion covers hot-rolled and cold-rolled alloy and structural alloy-steel sheet and strip. Alloy steel is furnishedto chemical composition requirements and is intended primarily for general or miscellaneous use where bending and moderateforming is a requirement. Structural alloy steel is furnished to
4、chemical composition requirements and to specific mechanicalproperty requirements which may include tension tests, hardness tests, or other commonly accepted mechanical tests.1.2 If material of a higher degree of uniformity of internal soundness and freedom from surface imperfections is required,ref
5、erence should be made to Specification A507.1.3 Alloy and structural alloy-steel sheet and strip are not produced to internal cleanliness requirements. Normally surfaceimperfections are not objectionable, and a good finish is not a prime requirement.1.4 The formability of structural alloy steel decr
6、eases with increasing yield strength or hardness. Therefore, product design inrelation to the mechanical properties of the grade used must be considered.1.5 The material covered by this specification may be furnished in several conditions: heat treatments, surface conditions, andedges, as specified
7、herein, in coils or cut lengths.1.6 The values stated in inch-pound units are to be regarded as the standard. SI units are provided for information only.2.

General Requirements and Ordering Information4.1 Material supplied to this specification shall conform to Specification A505, which includes the general requirements andestablishes the rules for the ordering information that should be complied with when purch
34、asing material to this specification.4.2 In addition to the ordering information required by Specification A505, the following shall also be included:4.2.1 Mechanical properties required for structural quality, when applicable,4.2.2 Surface finish, if other than standard (see 8.1), and4.2.3 Surface
35、treatment, if other than standard (see 8.2).5. Materials and Manufacture5.1 RollingThe material shall be furnished either hot-rolled or cold-rolled, as specified on the order.5.2 Heat Treatment:5.2.1 Hot-RolledHot-rolled material shall be furnished in one of the following conditions, as specified on
36、 the order:5.2.1.1 As-rolled,5.2.1.2 Annealed,5.2.1.3 Normalized, or5.2.1.4 Normalized-and-tempered.5.2.2 Cold-RolledCold-rolled material shall be fully annealed after cold-rolling. (Temper, skin, or roller leveling for thecontrol of flatness, which does not significantly affect the properties, may
37、be performed after annealing.)6. Chemical Requirements6.1 The heat analysis shall conform to the requirements for the grade specified on the order.6.1.1 Alloy SteelThe grade shall be specified in accordance with either 6.1.1.1 or 6.1.1.2.6.1.1.1 Standard steels listed in Table 1 are those commonly p
38、roduced for alloy steel sheet and strip.6.1.1.2 Nonstandard steel grades may be specified using the ranges and limits shown in Table 2.6.1.2 Structural Alloy SteelThe grade shall be specified as outlined in 6.1.1. However, since different mechanical propertiesmay be expected for each of the many che
