4.1.2Quantity,
4.1.3Grade designation(see Table1),
4.1.4Options in the specification,and
4.1.5Supplementary requirements desired,including the standards of acceptance.
5.Materials and Manufacture
5.1Materials for this specification shall be melted by conventional processes used for reactive metals.Typical meth-ods include the consumable electrode and induction-slag, plasma arc,induction-skull,and electron beam melting pro-cesses.
6.Chemical Composition
6.1Pour Analysis—An analysis of each pour shall be made by the producer from a sample such as a casting or test bar that is representative of the pour.The chemical composition deter-mined shall conform to the requirements specified for the relevant grade in Table1.
6.1.1The elements listed in Table1are intentional alloy additions or elements which are inherent to the manufacture of titanium sponge,ingot or mill product.
6.1.1.1Elements other than those listed in Table1are deemed to be capable of occurring in the grades listed in Table 1by and only by way of unregulated or unanalyzed scrap additions to the ingot melt.Therefore product analysis for elements not listed in Table1shall not be required unless specified
and shall be considered to be in excess of the intent of this specification.
6.1.2Elements intentionally added to the melt must be identified,analyzed,and reported in the chemical analysis. 6.2When agreed upon by the producer and the purchaser and requested by the purchaser in his written purchase order, chemical analysis shall be completed for specific residual elements not listed in this specification.
6.3Product Analysis—Product analysis tolerances do not broaden the specified heat analysis requirements,but cover variations between laboratories in the measurement of chemi-cal content.The producer shall not ship material which is outside the limits specified in Table1for the applicable grade. Product analysis limits shall be as specified in Table2.
6.4Sampling—Samples for chemical analysis may be made by the purchaser on a representative casting from any lot.Due to the possibility of oxygen or other interstitial contamination, samples for oxygen,carbon,hydrogen,and nitrogen analysis shall be taken no closer than1⁄4in.(6.3mm)to a cast surface except that castings too thin for this shall be analyzed on representative material.The chemical composition determined shall conform to the analysis in Table1within the check analysis variations shown in Table2or shall be subject to rejection by the purchaser.
7.Heat Treatment
7.1Unless otherwise specified in the contract,all castings will be supplied in the as-cast condition except when post-weld heat treatment is required.
7.2If post-weld heat treatment is required,it shall consist of
a stress relief performed at1075625°F(580614°C)for Grades C-2,C-3,C-7,C-8,C-12,C-16and C-17,and12006 25°F(650614°C)for Grades C-5,C-6,C-9,C-18,and C-38. Time at temperature shall be a minimum of1⁄2h plus an additional1⁄2h at temperature per inch of thickness for section sizes greater than1in.(25mm).After heat treatment,the castings should be cooled in air or in the furnace to ambient temperature unless otherwise agreed upon between the pur-chaser and producer.
8.Methods of Chemical Analysis
8.1The chemical analysis shall normally be conducted using the ASTM standard test methods referenced in2.1.Other industry standard methods may be used where the ASTM test methods in2.1do not adequately cover the elements in the material or by agreement between the producer and purchaser. Alternate techniques are discussed in Guide E2626.
9.Workmanship,Finish,and Appearance
9.1All castings shall be made in a workman-like manner and shall conform to the dimensions in drawings furnished by the purchaser before manufacturing is started.If the pattern is supplied by the purchaser,the dimensions of the casting shall be as predicted by the pattern.
9.2The surface of the casting shall be free of adhering mold material,scale,cracks,and hot tears as determined by visual examination.Other surface discontinuities shall meet the visual acceptance standards specified in the order.Practice A802/ A802M or other visual standards may be used to define acceptable surface discontinuities andfinish.Unacceptable surface discontinuities shall be removed and their removal verified by visual examination of the resultant cavities.
10.Repair by Welding
10.1If repairs are required,these shall be made using a welding procedure and operators certified to quality require-ments established by the producer.The procedures developed shall be consistent with standard practices recommended for reactive metal alloys.The producer shall maintain documenta-tion on procedure and welder qualifications.Procedure modi-fications or special arrangements shall be as agreed upon between the producer and the
purchaser. B367−13
