Scope*1.1 This specification covers the general requirements for hot-rolled, heavy-thickness sheet and strip in coils.1.2 It applies to Specifications A414/A414M, A424/A424M, and A1018/A1018M.1.3 Thi

7、rements of the individual material specification shall prevail over those ofthis general specification.1.5 Annex A1 lists permissible variations in dimensions and mass (see Note 2) in SI metric units. The values listed are notexact conversions of the values listed in the inch-pound tables, but inste
8、ad are rounded or rationalized values. Conformance toAnnex A1 is mandatory when the “M” specification is used.NOTE 2The term weight is used when inch-pound units are the standard. However, under SI, the preferred term is mass.1.6 The values stated in either SI units or inch-pound units are to be reg
9、arded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.7 This specification and the applicable material specifi
10、cations are expressed in both inch-pound units and SI units. However,unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-poundunits.2.

21、ing elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, or copper 0.60.3.1.2.1 DiscussionIn all carbon steels small quantities of certain residual elements unavoidably retained from raw materials are sometimes foundwhich are not specified or required, such as copper, nickel
22、, molybdenum, chromium, etc. These elements are considered asincidental and are not normally determined or reported.3.1.3 high-strength, low-alloy steela specific group of steels in which higher strength, and in some cases additional resistanceto atmospheric corrosion or improved formability, are ob

Materials
32、 and Manufacture5.1 Melting PracticeHot-rolled heavy thickness sheet and strip coils are normally produced from rimmed, capped, orsemi-killed steel. If either coarse or fine-grain practice is specified, special soundness steel will be furnished.5.2 Steel may be produced as ingot-cast or strand-cast.
33、 When different grades of strand-cast steel are sequentially cast,identification and separation of the transition material is required.5.3 The steel shall be in the hot-rolled condition.6. Chemical Composition6.1 Cast or Heat (Formerly Ladle) AnalysisAn analysis of each heat or cast shall be made by
34、 the steel manufacturer todetermine the conformance with the appropriate requirement. The analysis shall be from a test sample preferably taken during thepouring of the heat or cast.6.1.1 Where the material is used for fabrication by welding, care must be exercised in selection of chemical compositi
35、on ormechanical properties to assure compatibility with the welding process and its effect on altering the properties.6.2 Product, Check, or Verification Analysis:6.2.1 Non-killed steels such as capped or rimmed steels are not technologically suited to product analysis due to the nonuniformcharacter
36、 of their chemical composition, and therefore, the tolerances in Table 1 do not apply. Product analysis is appropriate onthese types of steel only when misapplication is apparent, or for copper when copper steel is specified.6.2.2 For steels other than non-killed (capped or rimmed), product analysis
37、 may be made by the purchaser. The chemicalanalysis shall not vary from the limits specified by more than the amounts in Table 1. The several determinations of any elementin a cast shall not vary both above and below the specified range.6.2.3 Sampling for Product Analysis:6.2.3.1 To indicate adequat
38、ely the representative composition of a cast by product analysis, it is general practice to selectsamples to represent the steel, as fairly as possible, from a minimum number of pieces as follows: three pieces for lots up to 15tons included, and six pieces for lots over 15 tons.TABLE 1 Tolerances fo

41、red in 6.2.3.3.6.2.3.3 When the steel is not subject to tension test requirements, the samples for analysis must be taken by milling or drillingentirely through the sheet in a sufficient number of places so that the samples are representative of the entire sheet or strip. Thesampling may be facilita
42、ted by folding the sheet both ways, so that several samples may be taken at one drilling. Steel subjectedto certain heating operations by the purchaser may not give chemical analysis results that properly represent its originalcomposition. Therefore, users must analyze chips taken from the steel in
43、the condition in which it is received from the steelmanufacturer.6.3 Specimen PreparationDrillings or chips must be taken without the application of water, oil, or other lubricant, and mustbe free of scale, grease, dirt, or other foreign substances. They must not be overheated during cutting to the
44、extent of causingdecarburization. Chips must be well mixed and those too coarse to pass a No. 10 sieve or too fine to remain on a No. 30 sieveare not suitable for proper analysis. Sieve size numbers are in accordance with Specification E11.6.4 Test MethodsIn case a referee analysis is required and a
45、greed upon to resolve a dispute concerning the results of achemical analysis, the procedure for performing the referee analysis must be in accordance with the latest issue of Test Methods,Practices, and Terminology A751, unless otherwise agreed upon between the manufacturer and the purchaser.7. Mech
46、anical Properties7.1 The mechanical property requirements, number of specimens, and test locations and specimen orientation shall be inaccordance with the applicable product specification.7.2 Unless otherwise specified in the applicable product specification, test specimens must be prepared in accor
47、dance with TestMethods and Definitions A370.7.3 Mechanical tests shall be conducted in accordance with Test Methods and Definitions A370.7.4 To determine conformance with the product specification, a calculated value shall be rounded to the nearest 1 ksi tensilestrength and yield point or yield stre
48、ngth, and to the nearest unit in the right hand place of figures used in expressing the limitingvalue for other values in accordance with the rounding off method given in Practice E29.8.
