1、Designation: A1031/A1031M 12 (Reapproved 2017)Standard Specification forSteel, Sheet and Strip, Heavy-Thickness Coils, Alloy,Drawing Steel and Structural Steel, Hot-Rolled1This standard is issued under the fixed designation A1031/A1031M; the number immediately following the designation indicates the
2、year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers hot-rolled, heavy thickn
3、esscoils beyond the size limits of Specifications A506 and A507.1.2 The product is available in three designations: AlloySteel, Drawing Steel, and Structural Alloy Steel.1.3 Alloy steel is furnished to chemical composition re-quirements and is intended primarily for general or miscella-neous use whe
4、re bending and moderate forming is a require-ment.1.4 Drawing steel is produced principally for applicationsinvolving severe cold plastic deformation such as deep drawnor severely formed parts.1.4.1 Drawing steel may be furnished in several conditions,heat treatments, surface finishes, and edges, as
5、 specified herein.1.5 Structural steel is furnished to chemical compositionrequirements and to specific mechanical property requirementswhich may include tension tests, hardness tests, or othercommonly accepted mechanical tests.1.5.1 The formability of structural steel decreases withincreasing yield
6、 strength or hardness. Therefore, product de-sign in relation to the mechanical properties of the grade usedmust be considered.1.6 This material is available only in coils described asfollows:Product Size Limits, Coils OnlyWidth, in. mm Thickness, in. mmStrip Over 8 to 12, incl 0.230 to 1.000, inclO
