Materials and Manufacture5.1 Melting ProcessUnless otherwise specified in the individual material specific

21、ation, the steel may be made by any processthat produces material that conforms to the specified requirements.5.2 Hot or Cold RollingThe sheet and strip shall be produced by hot rolling or cold rolling, as specified in the individualmaterial specification and as specified on the order.5.3 Heat Treat

22、mentWhen heat treatment is required, it shall be performed in accordance with the requirements specified inthe individual material specification. Heat treatment may be performed by either the manufacturer or the purchaser; however, ifthe purchaser intends to perform the heat treatment, it shall be s

23、o stated on the order.5.3.1 Heat treatment terms shall be in accordance with Terminology A919.6.Chemical Requirements6. Chemical Requirements Chemical Requirements6.1 Cast or Heat Analysis of each cast or heat shall be made by the manufacturer to determine the percentage of elementsspecified in the

The composition thus determined shall conform to the requirements for product analysis specified in the individual m

26、aterialspecification or on the order; however, if only cast or heat analysis requirements are specified in the material specification or onthe order, the composition determined on product analysis shall conform to those requirements subject to the product analysistolerances specified in Table 2.6.3

27、Referee AnalysisIn case referee analysis is required to resolve a dispute concerning the results of a chemical analysis, theprocedures for performing the referee analysis shall be in accordance with Test Methods, Practices, and Terminology A751.7. Metallurgical Structure7.1 The requirements for meta

28、llurgical structure, if any, shall be as specified in the individual material specification.8. Mechanical Property Requirements8.1 RequirementsThe requirements for mechanical properties, if any, shall be as specified in the individual materialspecification.8.2 Number of TestsThe number of specimens

29、shall be as specified in the individual material specification.8.3 Location and Orientation of Tension Test SpecimensUnless otherwise specified in the individual material specification,tension test specimens shall be the full thickness of the material. The test coupons shall be taken from the materi

30、al in its finishedcondition except as otherwise provided in 8.4; shall be taken approximately midway between the edge and centerline of the sheetor strip; and shall be taken such that the long axis of the test specimen will be transverse to the final direction of rolling.8.4 Heat Treatment of Test C

31、oupons:8.4.1 When heat treatment is required by the material specification and is to be performed by the purchaser or his agent, andthe material is to be supplied by the manufacturer in a condition other than that required by the material specification, the materialshall be qualified on the basis of

32、 tests made on specimens taken from coupons, obtained from the material in its as-shippedcondition, that have been heat treated in accordance with the requirements specified in the material specification or on the order.If the heat-treatment temperatures are not specified, the manufacturer shall hea

33、t treat the coupons under conditions he considersappropriate.A505 1228.4.2 When specified on the order, the test coupons may be subjected to additional heat treatment to simulate thermal treatmentsthat will be used during fabrication.8.4.3 The purchaser shall be informed of the procedures followed i

34、n heat treating the test coupons.8.5 Test Methods:8.5.1 All tests shall be conducted in accordance with Test Methods and Definitions A370.8.5.2 Yield strength shall be determined either by the 0.2 % offset method or by the 0.5 % extension-under-load method.9. Quality9.1 GeneralSheet and strip furnis

35、hed under this specification shall be clean, sound, and free of internal or externalimperfections which would make the material unsuitable for the intended application. Care should be taken to avoid cracks, seams,slivers, grooves, laminations, pits, blisters, buckles, coil breaks, creases, holes, pi

36、ckling stains and patches, ragged and torn edges,and “rolled-in” dirt and scale.9.2 Surface FinishThe degree or amount of surface imperfections on material in cut lengths shall be such that only areasonable amount of metal finishing is required. Slight surface imperfections that are completely remov

37、able without reducing thethickness below the minimum permissible limits shall not be considered to be defects. Coils may contain some abnormal defectssuch as holes, welds, etc., which render a portion of the coil unusable, since the inspection of coils does not afford the sameopportunity to reject p

38、ortions containing defects as is the case with cut lengths. However, an excessive number of abnormalimperfections is cause for rejection.10. Edges10.1 EdgesThe types of edges procurable in hot-rolled and in cold-rolled alloy-steel sheet and strip are as follows:10.2 Hot-Rolled Sheet and Strip:10.2.1

39、 Mill EdgeNormal edge produced in hot rolling that does not conform to any definite contour.10.2.2 Cut EdgeApproximately square edge resulting from the cutting of sheet into one or more desired widths by means ofrotary knives (slit edge) or blade shears (sheared edge).10.2.3 Square EdgeType of mill

40、edge produced by hot edge-rolling; furnished on strip only.10.3 Cold-Rolled Sheet:10.3.1 Cut EdgeSame description as shown in 10.2.2 for hot-rolled sheet and strip.10.4 Cold-Rolled Strip:10.4.1 No. 1 EdgePrepared edge of a specified round or square contour that is produced when a very accurate width

41、 isrequired.10.4.2 No. 2 EdgeNatural mill edge carried through the cold rolling from the hot-rolled strip without additional processingof the edge.10.4.3 No. 3 EdgeApproximately square edge produced by slitting.10.4.4 No. 4 EdgeRounded edge produced by edge rolling either the natural edge of hot-rol

42、led strip or slit-edge strip. Usedwhen an approximately round edge is desired and when the finish of the edge is not important.10.4.5 No. 5 EdgeSquare edge produced by edge rolling or filing for the purpose of eliminating burr.10.4.6 No. 6 EdgeSquare edge produced by edge rolling the natural edge of

43、 hot-rolled strip or slit-edge strip, when the widthtolerances and finish required are not as exacting as for the No. 1 Edge.11. Permissible Variations in Dimensions11.1 The permissible variations in dimensions (see Table 3) for hot-rolled and cold-rolled alloy steel sheet and strip shall be inaccor

44、dance with Tables 4-22.12. Identification of Product12.1 As a minimum, the material shall be identified with the manufacturers name or brand, the specification designation,weight, purchasers order number, and material identification which is traceable to the heat or cast.12.2 The identification shal

45、l be legibly stenciled on top of each lift or shown on a tag attached to each coil or shipping unit.12.3 When specified on the order, each sheet shall be identified as agreed upon.13. Retests13.1 The retest provisions of Test Methods and Definitions A370 shall apply.13.2 If the results of any tests

46、do not conform to the specified requirements, (unless otherwise specified in the individualmaterial specification), retests may be made on double the original number of specimens from the same lot, each of which mustconform to the requirements specified. If the results of the retests do not conform

47、to the specified requirements, the lot shall berejected.14. Inspection and Testing14.1 When the order specifies that the purchaser will inspect the material and witness testing, the inspector representing thepurchaser shall have entry at all times while work on the contract of the purchaser is being

48、 performed, to all parts of theA505 123manufacturers works that concern the manufacture of the material ordered. The manufacturer shall afford the inspector allreasonable facilities to satisfy the inspector that the material is being furnished in accordance with the specification.14.2 All tests (exc

49、ept product analysis) and inspection shall be made at the place of manufacture before shipment, unlessotherwise specified on the order, and shall be so conducted as not to interfere unnecessarily with the operation of the works.15. Rework and Retreatment15.1 If inspection and test results fail to conform to the specified requirements, the material may be reworked or retreated, ifthe manufacturer can assure that the cause of failure is curable and that the quality of the material shall conform to the specifiedrequirements. After retreatment, testing sha
