Metallurgical Structure7.1 The requirements for metallurgical structure, if any,shall be as specified in the individual material specification.8. Mechanical Property Requirements8.1 RequirementsThe requirements for mechanical prop-erties,

25、 if any, shall be as specified in the individual materialspecification.8.2 Number of TestsThe number of specimens shall be asspecified in the individual material specification.8.3 Location and Orientation of Tension Test SpecimensUnless otherwise specified in the individual material specifi-cation,

26、tension test specimens shall be the full thickness of thematerial. The test coupons shall be taken from the material inits finished condition except as otherwise provided in 8.4; shallbe taken approximately midway between the edge and center-line of the sheet or strip; and shall be taken such that t

27、he longaxis of the test specimen will be transverse to the final directionof rolling.8.4 Heat Treatment of Test Coupons:8.4.1 When heat treatment is required by the materialspecification and is to be performed by the purchaser or hisagent, and the material is to be supplied by the manufacturer ina c

28、ondition other than that required by the material specifica-tion, the material shall be qualified on the basis of tests madeon specimens taken from coupons, obtained from the materialin its as-shipped condition, that have been heat treated inaccordance with the requirements specified in the material

29、specification or on the order. If the heat-treatment temperaturesare not specified, the manufacturer shall heat treat the couponsunder conditions he considers appropriate.8.4.2 When specified on the order, the test coupons may besubjected to additional heat treatment to simulate thermaltreatments th

31、fset method or by the 0.5 % extension-under-load method.9. Quality9.1 GeneralSheet and strip furnished under this specifi-cation shall be clean, sound, and free of internal or externalimperfections which would make the material unsuitable forthe intended application. Care should be taken to avoid cr

32、acks,seams, slivers, grooves, laminations, pits, blisters, buckles, coilbreaks, creases, holes, pickling stains and patches, ragged andtorn edges, and “rolled-in” dirt and scale.9.2 Surface FinishThe degree or amount of surface im-perfections on material in cut lengths shall be such that only areaso

33、nable amount of metal finishing is required. Slight surfaceimperfections that are completely removable without reducingthe thickness below the minimum permissible limits shall notbe considered to be defects. Coils may contain some abnormaldefects such as holes, welds, etc., which render a portion of

34、 thecoil unusable, since the inspection of coils does not afford thesame opportunity to reject portions containing defects as is thecase with cut lengths. However, an excessive number ofabnormal imperfections is cause for rejection.10. Edges10.1 EdgesThe types of edges procurable in hot-rolledand in

35、 cold-rolled alloy-steel sheet and strip are as follows:10.2 Hot-Rolled Sheet and Strip:10.2.1 Mill EdgeNormal edge produced in hot rolling thatdoes not conform to any definite contour.A 505 00 (2005)210.2.2 Cut EdgeApproximately square edge resultingfrom the cutting of sheet into one or more desire

36、d widths bymeans of rotary knives (slit edge) or blade shears (shearededge).10.2.3 Square EdgeType of mill edge produced by hotedge-rolling; furnished on strip only.10.3 Cold-Rolled Sheet:10.3.1 Cut EdgeSame description as shown in 10.2.2 forhot-rolled sheet and strip.10.4 Cold-Rolled Strip:10.4.1 N
