19、ime.4. Ordering Information4.1 Orders for castings to this specification shall include thefollowing as required, to describe the requirements adequately:4.1.1 Description of the castings by pattern number ordrawing. Dimensional tolerances shall be included on thecasting drawing,4.1.2 Quantity,4.1.3

20、Grade designation (see Table 1),4.1.4 Options in the specification, and4.1.5 Supplementary requirements desired, including thestandards of acceptance.5. Materials and Manufacture5.1 Materials for this specification shall be melted byconventional processes used for reactive metals. Typical meth-ods i

21、nclude the consumable electrode and induction-slag,plasma arc, induction-skull, and electron beam melting pro-cesses.6. Chemical Composition6.1 Pour AnalysisAn analysis of each pour shall be madeby the producer from a sample such as a casting or test bar thatis representative of the pour. The chemic

22、al composition deter-mined shall conform to the requirements specified for therelevant grade in Table 1.6.1.1 The elements listed in Table 1 are intentional alloyadditions or elements which are inherent to the manufacture oftitanium sponge, ingot or mill product.6.1.1.1 Elements other than those lis

23、ted in Table 1 aredeemed to be capable of occurring in the grades listed in Table1 by and only by way of unregulated or unanalyzed scrapadditions to the ingot melt. Therefore product analysis forelements not listed in Table 1 shall not be required unlessspecified and shall be considered to be in exc

24、ess of the intentof this specification.6.1.2 Elements intentionally added to the melt must beidentified, analyzed, and reported in the chemical analysis.6.2 When agreed upon by the producer and the purchaserand requested by the purchaser in his written purchase order,chemical analysis shall be compl

25、eted for specific residualelements not listed in this specification.6.3 Product AnalysisProduct analysis tolerances do notbroaden the specified heat analysis requirements, but covervariations between laboratories in the measurement of chemi-cal content. The producer shall not ship material which iso

26、utside the limits specified in Table 1 for the applicable grade.Product analysis limits shall be as specified in Table 2.6.4 SamplingSamples for chemical analysis may be madeby the purchaser on a representative casting from any lot. Dueto the possibility of oxygen or other interstitial contamination

27、,samples for oxygen, carbon, hydrogen, and nitrogen analysisshall be taken no closer than14 in. (6.3 mm) to a cast surfaceexcept that castings too thin for this shall be analyzed onrepresentative material. The chemical composition determinedshall conform to the analysis in Table 1 within the checkan

28、alysis variations shown in Table 2 or shall be subject torejection by the purchaser.7. Heat Treatment7.1 Unless otherwise specified in the contract, all castingswill be supplied in the as-cast condition except when post-weldheat treatment is required.7.2 If post-weld heat treatment is required, it s

29、hall consist ofa stress relief performed at 1075 6 25F (580 6 14C) forGrades C-2, C-3, C-7, C-8, C-12, C-16 and C-17, and 1200 625F (650 6 14C) for Grades C-5, C-6, C-9, C-18, and C-38.Time at temperature shall be a minimum of12 h plus anadditional12 h at temperature per inch of thickness for sectio

30、nsizes greater than 1 in. (25 mm). After heat treatment, thecastings should be cooled in air or in the furnace to ambienttemperature unless otherwise agreed upon between the pur-chaser and producer.8. Methods of Chemical Analysis8.1 The chemical analysis shall normally be conductedusing theASTM stan

31、dard test methods referenced in 2.1. Otherindustry standard methods may be used where the ASTM testmethods in 2.1 do not adequately cover the elements in thematerial or by agreement between the producer and purchaser.Alternate techniques are discussed in Guide E2626.9. Workmanship, Finish, and Appea

32、rance9.1 All castings shall be made in a workman-like mannerand shall conform to the dimensions in drawings furnished bythe purchaser before manufacturing is started. If the pattern issupplied by the purchaser, the dimensions of the casting shallbe as predicted by the pattern.9.2 The surface of the

33、casting shall be free of adhering moldmaterial, scale, cracks, and hot tears as determined by visualexamination. Other surface discontinuities shall meet the visualacceptance standards specified in the order. Practice A802/A802M or other visual standards may be used to defineacceptable surface disco

34、ntinuities and finish. Unacceptablesurface discontinuities shall be removed and their removalverified by visual examination of the resultant cavities.B367 13 (2017)2TABLE1ChemicalRequirementsComposition,WeightPercentA,B,C,D,EGradeUNSNumberCarbon,max.Oxygenrangeormax.Nitrogen,max.Hydrogen,max.Ironran
