Oct 13, 2017

              The new national standard of titanium and titanium alloy will be carried out soon


Recently, a "titanium and titanium alloy brand and chemical composition of the new national standard will soon begin to implement" the news caused many titanium circles concern, and launched the topic discussion. The new national standard in the former version of what? And? It will bring what influence to the enterprise? The reporter a telephone interview with the titanium industry renowned experts BaoTi group senior engineer Ma Honghai.


Ma Honghai told reporters, the new national standard by the People's Republic of China State Administration of Quality Supervision Inspection and quarantine China National Standardization Management Committee jointly issued in December 2016, will be implemented on November 1st this year. This standard is a revision of GB/T3620.1-2007, specified in the standard TA0, TA1, TA2, TA3 pure titanium grades respectively corresponding to the 2007 (1994 edition) before the release of the relevant national standards, national military standard titanium industry standard, the corresponding TA0, TA1, TA2, TA3 grade and chemical composition.


Reporters found that in the new national standard to restore the 1994 edition of pure titanium brand, only the brand was revised, still can find the corresponding alloy brand, the chemical composition is consistent. Recovery of pure titanium grades in the 1994 edition of the new national standard, the main reason is that the military enterprises has been using the 1994 version, in 1994 ~2007 years has been set for military products to make changes, must use the first grade, so the new brand of pure titanium in the GB and pure titanium grades in version 1994 of the corresponding, and chemical components.


In addition, the new national standard stipulated in the TA1GELI, TA1G, TA1G-1, TA2GELI, TA2G, TA3GELI, TA3G, TA4GELI, TA4G, 2965-2007, GB/T respectively corresponding to GB/T 3621-2007, GB/T 3622-2012, GB/T 3623-2007, GB/T 3624-2010, GB/T 3625-2007, GB/T 12769-2007, GB/T 13810-2007, GB/T 14845-2007, GB/T 16598-2013, GB/T 26057-2010, GB/T 26058-2010, GB/T 26059-2010, GB/T 26723-2011, GJB 2218A-2008, GJB 2505A-2008, YS/T 658-2007, YS/T 750-2011, YS/T 794-2012, YS/T 795-2012, YS/T 885-2013 in the corresponding TA1ELI, TA1, TA-1, TA2ELI, TA2, TA3ELI, TA3, TA4ELI and TA4 grade and chemical composition. Ma Honghai said, the new national standard of TA1G, TA2G, TA3G, TA4G and TA1, the 2007 edition of the TA2, TA3, TA4 pure titanium grades should be relative, so, also joined the new national standard in the 2007 edition of brand content, but with the drafting of the "G" brand in front of titanium and titanium alloy brand new heavy name, is easy to distinguish between the 2007 and 1994 version of pure titanium grades. It is worth noting that the new national standard will be implemented in November this year is on the chemical composition of the executive, but did not modify the material standard, plate, bar, pipe and other materials are still the implementation of the 2007 version of the standard, Ma Honghai told reporters that the new standard is expected to materials available in 2018.

It is worth noting that the new national standard, based on the previous version, and joined the 1994 edition, while the material standards are not updated, easy to confuse people. Ma Honghai specially prompted enterprises and practitioners, the need to pay attention to the new and old standards in advance to switch, so as to avoid confusion, bring unnecessary losses.


At present, it has been less than three months since the implementation of the new national standard, and enterprises are still lack of understanding and understanding of the new national standard, especially small and medium-sized enterprises. Ma Honghai believes that the production enterprises in this period of time, still need to pay more attention to actively organize the study to the new national standard, the new national standard implementation of customer.


Reporters learned from the production enterprises, so far, the production of titanium and titanium alloy, the old GB is still allowed to use. The titanium and titanium alloy grades used in aviation, aerospace and civil enterprises generally refer to the 2007 edition standard, while most of the military enterprises refer to the 1994 edition standard. As of now, enterprises only indicate the material standard contract, and in November 1st after the enterprise in the production process, which should carry out the standards? Ma Honghai believes that the signing of the contract from now on, the seller and the buyer to deliver the contract time, must indicate the material chemical composition standard version version version number, and quasi cited references the year for undated references, it will default to the latest version, will cause unnecessary trouble.


Secondly, the current inventory of products enterprises should be how to deal with? Ma Honghai suggested that enterprises to produce finished or semi-finished products should be finished label in November 1st before switching of the old and the new standard, take measures in advance, clear what is the implementation of the version of the TA label.


According to insiders, the new standard for export products brand provisions are more clear than the previous version, and the United States and other foreign standards are close, taking into account the reality of the production enterprises. Ma Honghai told reporters, in fact, in version 2007, the chemical properties of titanium and titanium alloy have been American Standard and equivalent. The new national standard set 1994 edition and 2007 edition as a whole, more detailed, perfect, as long as enterprises properly handle, master the contents of the new national standard, will have long-term significance for the development of enterprises.
