Standard Specification for Titanium and Titanium Alloy Castings

ABSTRACT
This specification covers the standard requirements for titanium and titanium alloy castings intended for general corrosion resistant and industrial applications. Materials for this specification shall be melted by conventional processes used for reactive metals such as consumable electrode and induction-slag, plasma arc, induction-skull, and electron beam melting processes. The materials shall undergo chemical, pour, and product analysis to determine the chemical composition which shall conform to the requirements for nitrogen, carbon, hydrogen, iron, oxygen, aluminum, vanadium, tin, ruthenium, palladium, cobalt, molybdenum, chromium, nickel, niobium, zirconium, silicon, and titanium. All castings shall be supplied in the as-cast condition except when post-weld heat treatment is required wherein it shall consist of a stress relief performed at certain temperatures. The surface of the castings shall be free of adhering mold material, scale, cracks, and hot tears as determined by visual inspection.
SCOPE
1.1 This specification covers titanium and titanium alloy castings intended for general corrosion resistant and industrial applications. as follows:

1.1.4 Grade C-7—UNS R52700. Unalloyed titanium plus 0.12 to 0.25 % palladium,  
1.1.5 Grade C-8—UNS R52700. Unalloyed titanium plus 0.12 to 0.25 % palladium,  
1.1.6 Grade C-9—UNS R56320. Titanium alloy (3 % aluminum, 2.5 % vanadium),  
1.1.7 Grade C-12—UNS R53400. Titanium alloy (0.3 % molybdenum, 0.8 % nickel),  
1.1.8 Grade C-16—UNS R52402. Unalloyed titanium plus 0.04 to 0.08 % palladium,  
1.1.9 Grade C-17—UNS R52252. Unalloyed titanium plus 0.04 to 0.08 % palladium, and  
1.1.10 Grade C-38—UNS R54250. Titanium alloy (4 % aluminum, 2.5 % vanadium, 1.5 % iron).  
1.2 This specification is intended for use of purchasers and/or producers of reactive metal castings for defining the requirements and assuring the properties of castings for unique corrosion-resistant applications, that is, not for commodity items which must meet all potential purchasers’ requirements.  
1.2.1 Users are advised to use the specification as a basis for obtaining castings which will meet minimum acceptance requirements established and revised by consensus of the members of the committee.  
1.2.2 User requirements considered more stringent may be met by the addition to the purchase order of one or more supplementary requirements, which may include, but are not limited to, those listed in Sections S1 through S8.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 lot, n—shall consist of all castings of the same design produced from the same pour.
3.1.2 pour, n—shall consist of all material melted and cast at one time.
4. Ordering Information
4.1 Orders for castings to this specification shall include the following as required, to describe the requirements adequately:
4.1.1 Description of the castings by pattern number or drawing. Dimensional tolerances shall be included on the casting
drawing,
4.1.2 Quantity,
4.1.3 Grade designation (see Table 1),
4.1.4 Options in the specification, and
4.1.5 Supplementary requirements desired, including the standards of acceptance.
5. Materials and Manufacture
5.1 Materials for this specification shall be melted by conventional processes used for reactive metals. Typical methods include
the consumable electrode and induction-slag, plasma arc, induction-skull, and electron beam melting processes.
6. Chemical Composition
6.1 Pour 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 determined shall conform to the requirements specified for the relevant grade
in Table 1.
6.1.1 The elements listed in Table 1 are intentional alloy additions or elements which are inherent to the manufacture of titanium
sponge, ingot or mill product.
6.1.1.1 Elements other than those listed in Table 1 are deemed to be capable of occurring in the grades listed in Table 1 by and
only by way of unregulated or unanalyzed scrap additions to the ingot melt. Therefore product analysis for elements not listed in
Table 1 shall not be required unless specified and shall be considered to be in excess of the intent of this specification.
6.1.2 Elements intentionally added to the melt must be identified, analyzed, and reported in the chemical analysis.
6.2 When 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.
6.3 Product Analysis—Product analysis tolerances do not broaden the specified heat analysis requirements, but cover variations
between laboratories in the measurement of chemical content. The producer shall not ship material which is outside the limits
specified in Table 1 for the applicable grade. Product analysis limits shall be as specified in Table 2.
6.4 Sampling—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 than ⁄4 in. (6.3 mm) 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 Table 1 within the check analysis variations shown

A
At minimum, one pour analysis shall be completed and reported for all elements listed for the respective grade in this table.
B
If the casting is subjected to thermal or chemical processing following the pour, final product hydrogen shall be reported in lieu of pour hydrogen. Lower hydrogen may be obtained by negotiation with the manufacturer.
C
Single values are maximum. The percentage of titanium is determined by difference.

B367 − 13 (2017)
D
Other elements need not be reported unless the concentration level is greater than 0.1 % each, or 0.4 % total. Other elements may not be added intentionally. Other elements may be present in titanium or titanium
alloys in small quantities and are inherent to the manufacturing process. In titanium these elements typically include aluminum, vanadium, tin, chromium, molybdenum, niobium, zirconium, hafnium, bismuth, ruthenium,
palladium, yttrium, copper, silicon, cobalt, tantalum, nickel, boron, manganese, and tungsten.
E
The purchaser may, in the written purchase order, request analysis for specific elements not listed in this specification.

agreed upon between the purchaser and producer.
8. Methods of Chemical Analysis
8.1 The chemical analysis shall normally be conducted using the ASTM standard test methods referenced in 2.1. Other industry
standard methods may be used where the ASTM test methods in 2.1 do 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
9.1 All 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.
9.2 The 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 and finish. Unacceptable surface discontinuities
shall be removed and their removal verified by visual examination of the resultant cavities.
