1、Designation: A1031/A1031M 10Standard 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 theyear of original a
2、doption 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 thicknesscoils beyond th
3、e 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 where bending and mod
4、erate 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 specified herein.
5、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 strength or hardn
6、ess. 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, inclOver 200 to 300 Ove
7、r 6.0 to 25Sheet Over 12 0.230 to 1.000, inclOver 300 from 6.0 through 251.7 Sheet and strip in coils of sizes noted in 1.6 are coveredby this specification only with the following provisions:1.7.1 The material is not to be converted into steel plates forstructural or pressure vessel use unless test
8、ed in completeaccordance with the appropriate sections of SpecificationsA6/A6M (plates provided from coils) or A20/A20M (platesproduced from coils). A plate produced in this manner is nolonger governed by this sheet steel specification and since thismaterial is now plate, the appropriate plate stand
9、ard must nowapply.1.7.2 The dimensional tolerances of Specification A635/A635M are applicable to material produced to this specifica-tion.1.7.3 The material is to be fed directly from coils into ablanking press, drawing or forming operation, tube mill, rollingmill, or sheared or slit into blanks for
10、 subsequent drawing orforming.1.8 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may
11、result in non-conformancewith the standard.1.8.1 Within the text the SI units are shown in brackets.2.
