GB/T 15073-2014Casting titanium and titanium alloys (English PDF)

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). The responsible drafting organizations of this standard.

1 Scope

GB/T 15073-2014 is the Chinese national standard on casting titanium and titanium alloys, in the field of metallurgy. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 3 September 2014 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 June 2015. Classification: ICS 77.120.50, CCS J31. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

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.
