Dimensions and Permissible Variation9.1 Units o

42、f Measure:9.1.1 SelectionThis specification requires that the purchaser selects the units (SI or inch-pound) to be used for productcertification. In the absence of a stated selection of units on the purchase order, this selection may be expressed by the purchaserin several alternate forms listed in

43、order of precedence.9.1.1.1 If the purchaser and supplier have a history of using specific units, these units shall continue to be certified untilexpressly changed by the purchaser.9.1.1.2 In the absence of historic precedence, if the units used to define the product on the purchasers PO, specificat

44、ion, andengineering drawing are consistent, these units shall be used by the supplier for the product certification.9.1.1.3 If the purchasers selection of units is unclear, the units of measure shall be agreed upon between the purchaser andsupplier.9.1.2 Conversion of UnitsIf the suppliers test equi

45、pment does not report in the selected units, the test equipment units maybe converted to the selected units for certification purposes. Accurate arithmetic conversion and proper use of significant digitsshould be observed when performing this conversion. IEEE/ASTM SI 10 provides guidelines for the u

46、se of SI units. Annex Aprovides conversion tables and Annex B provides rules for conversion and significant digits.10. Special Requirements10.1 The microstructure shall consist of a fully recrystallized beta phase structure. Primary alpha and alpha prime (also knownas martensitic alpha) are not perm

47、itted in the microstructure when viewed at 100 magnification. The grain size in the annealedcondition shall be 5 or finer based upon Test Methods E112.10.2 Determine the beta transus temperature for each heat by a suitable method and report on the material certification ifrequired by the purchaser.1

48、0.3 Alpha case is not permitted for products supplied with a machined, ground, or chemically milled surface finish. For otherproducts, there willshall be no continuous layer of alpha case when examined at 100 magnification.10.4 All centerless ground or peeled and polished round bar 0.375 in. 9.5 mm

49、in nominal diameter shall be ultrasonicallyinspected at final diameter according to AMS 2631 Class A1. Equivalent test methods may be substituted when agreed upon bythe purchaser and supplierNOTE 1AMS 2631 contains varying flat bottom hole (FBH) requirements based on melting grades per AMS 2380. Since the FBH requirement forClass A1 is the same regardless of the melting grade, it is not necessary to specify the melting grade.11.
