1、Designation: A 1031 05Standard Specification forSteel, Sheet and Strip, Heavy-Thickness Coils, Alloy,Drawing Steel and Structural Steel, Hot-Rolled1This standard is issued under the fixed designation A 1031; the number immediately following the designation indicates the year oforiginal adoption or,
2、in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers hot-rolled, heavy thicknesscoils beyond the size limi
3、ts of Specifications A 506 and A 507.1.2 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 moderate for
4、ming 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.1.5 Struc
5、tural 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 hardness. Ther
6、efore, 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.

8、 be converted into steel plates forstructural or pressure vessel use unless tested in completeaccordance with the appropriate sections of SpecificationsA 6/A 6M (plates provided from coils) or A 20/A 20M (platesproduced from coils). A plate produced in this manner is nolonger governed by this sheet
9、steel specification and since thismaterial is now plate, the appropriate plate standard must nowapply.1.7.2 The dimensional tolerances of Specification A 635/A 635M are applicable to material produced to this specifica-tion.1.7.3 The material is to be fed directly from coils into ablanking press, dr
10、awing or forming operation, tube mill, rollingmill, or sheared or slit into blanks for subsequent drawing orforming.1.8 The values stated in either inch-pound units and SI units(metric) are to be regarded separately as standard. Within thetext the SI units are shown in brackets. The values stated in
11、each system are not exact equivalents; therefore, each systemmust be used independently of each other.2.
