GB/T 15006-2009General rules of dimensions, shape,surface quality, test method and inspection for elastic alloys (English PDF)

Foreword

This standard replaces GB/T 15006-1994 "elastic alloy size, shape, surface quality, test methods and inspection rules of general Provisions. " Compared with the standard GB/T 15006-1994 The main changes are as follows:

--- Added "Normative references" clause;

--- Add "greater than 1.80mm thickness without trimming the strip, the supply and demand sides agreed that its width tolerance allowed deviation from Table 1 of Regulation Fixed "(1994 version 1.1.1, this version 3.1.1);

--- Table 1, Table 2, the thickness of the strip is not greater than the diameter of 1.80mm, cold drawing materials tolerance unified 3 after the decimal point;

--- "By the agreement between the rectangular cross-section can supply cold-drawn bar" with "by agreement between the other cross-sectional shapes can supply cold-drawn Bar "(1994 version 1.3.3, this version 3.3.3);

--- Table 4 hot rolling and forging material tolerances breakdown (Table 4, 1994, edition Table 4);

--- "Nominal diameter of 6.0mm ~ 9.0mm hot rolled round material to be delivered into a disk" to "nominal diameter 6.0mm ~ Hot-rolled round 12.0mm material into a disk general delivery "(1994 version 1.4.2.1, this version 3.4.2.1);

--- Straight bending of delivery Rolled by "not more than 6mm/m" to "not more than 5mm/m" (1994 edition 1.4.2.2, this Version 3.4.2.2);

--- "Cold-drawn bars to allow a slight scratch the surface and a depth of no more than half the nominal diameter tolerances pits, pitting and straightening trace memory In the "increase" but should ensure the minimum size bars "provisions (1994 version 2.3, this version 4.3);

--- Table 5 test items "Vickers hardness", "cupping test", "wound test" test method consists of "YB53-64", "YB38- 64 "and" YB37-65 "to the current standard" GB/T 4340.1 "," GB/T 4156 "and" GB/T 2976 ", add" non-metallic Inclusions "test items, test methods according to GB/T 10561. Appendix A of this standard is a normative appendix. Appendix B of this standard is an informative annex. The standard proposed by China Iron and Steel Association. This standard is under the jurisdiction of the National Steel Standardization Technical Committee. This standard is mainly drafted by: Baoshan Iron & Steel Co., Ltd., Metallurgical Industry Information Standards Institute. Drafters of this standard. Shen Yi, ROCKETS, wear strong. This standard replaces the standards previously issued as follows:

--- GB/T 15006-1994. Size, shape, surface quality elastic alloy, General provisions of test methods and inspection rules

1 Scope

GB/T 15006-2009 is the Chinese national standard on general rules of dimensions, shape,surface quality, test method and inspection for elastic alloys, in the field of metallurgy. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 25 June 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 April 2010. Classification: ICS 77.080.01, CCS H58. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the general provisions elastic alloy size, shape, surface quality, test methods and inspection rules. This standard applies to elastic alloy cold-rolled strip, cold drawing materials, cold-drawn bars, cold-drawn and hot-rolled bars polished (forging) material.
