Foreword
This standard was drafted in accordance with the rules given in GB/T
1.1-2009.
This standard replaces GB/T 15073-1994 “Designation and chemical
composition of cast titanium and titanium alloys”. As compared with GB/T 15073-1994, the main technical changes of this standard are as follows. - CHANGE the standard name into “Casting titanium and titanium alloys”; - MODIFY the chapter name and chapter structure;
- ADD the title to each table;
- In the ZTC4 alloy, MODIFY the Al element composition range from “5.5% ~ 6.8%” to “5.50% ~ 6.75%”.
- ADD the chemical composition of ZTA9, ZTA10, ZTA15 and ZTA17 alloys;
- ADD the descriptions on the specific element analysis;
- ADD the descriptions on arbitration analysis;
- MODIFY the composition range and allowable deviation in Table 2; ADD
the range of Al element, Mo element, and V element; ADD the allowable
composition deviation of Zr element, Ni element, and Pd element.
This standard was proposed by AND shall be under the jurisdiction of the National Foundry Standardization Technical Committee (SAC/TC 54).

Casting titanium and titanium alloys
1 Scope
This standard specifies the designations, code and chemical composition, and chemical composition analysis methods for the casting titanium and titanium alloys.
This standard is applicable to titanium and titanium alloys of graphite type, tamping type, metal type and investment pattern precision casting.
2 Normative references
The following documents are essential to the application of this document. For the dated documents, only the versions with the dates indicated are applicable to this document; for the undated documents, only the latest version (including all the amendments) are applicable to this Standard.
GB/T 4698 (all parts) Methods for chemical analysis of sponge titanium, titanium and titanium alloys
GB/T 8063 Designation representation of cast nonferrous metals and their alloys
GB/T 8170 Rules of rounding off for numerical values and expression and
judgment of limiting values
3 Alloy designation, code and chemical composition
3.1 Designations and codes
3.1.1 The casting titanium and titanium alloy designations are presented in accordance with the provisions of GB/T 8063.
3.1.2 The casting titanium and titanium alloy code is composed of ZT plus A, B or C (A, B and C respectively represent type α, type β and type α + β alloy) and the sequence number, AND the sequence number shall make reference to the presentation method of the same type wrought titanium and titanium alloy. 3.2 Chemical composition
The chemical analysis sample is cut on a casting rod or cast AND is allowed to be cut from the runner. Chemical analysis sample must be clean, AND free of mixed impurities or casting surfaces.
4.2 Analytical methods and analysis reports
4.2.1 Chemical composition analysis shall follow the provisions of GB/T 4698 (all parts). As negotiated between the supplier and the purchaser, it may also use other test methods for analysis. In case of dispute on the result, it shall GB/T 4698 (all parts) for arbitration.
4.2.2 Where the purchaser requires providing the specific element content as not listed in this standard, the supplier shall analyze its chemical composition AND indicate it out in the analysis report.
4.2.3 The number of effective digits of the numerical value as reported in the chemical composition analysis shall be consistent with the number of the effective digits of the corresponding limit values in Table 1. The analysis value shall be rounded off in accordance with the provisions of GB/T 8170.
4.2.4 When the chemical composition is re-inspected and analyzed by the purchaser, the allowable composition deviation shall comply with the
requirements of Table 2.
4.2.5 When the chemical composition inspection is disqualified for the first time, it is allowed to re-take sample for analysis with the sample amount doubled, AND if any one item is disqualified in the second analysis results, it is deemed as disqualified.
