Panzhihua Iron and Steel takes the lead in filling the gaps in domestic vanadium and aluminum alloy testing standards

It was learned from the Municipal Economic Cooperation Bureau on August 16 that a few days ago, the Ministry of Industry and Information Technology issued and implemented Panzhihua Iron and Steel and jointly developed the "YB/T4908.
1-2021 Vanadium Aluminum Alloy Determination of vanadium content, including 6 industry standards for vanadium-aluminum alloy testing including ammonium persulfate oxidation-ferrous ammonium sulfate titration method, which fills the gap in domestic standards in this field
.
It is understood that in accordance with the "Twelfth Five-Year Plan for Comprehensive Utilization of Vanadium and Titanium Resources and Industrial Bases" formulated by the National Development and Reform Commission, Panzhihua Iron and Steel and other companies have increased their efforts in the development of new vanadium products and expanded the application of vanadium resources in non-steel fields.
The key direction is to develop aerospace-grade high-end vanadium aluminum alloy
.
In the standards released this time, the test objects include various grades of products such as master alloys and aerospace grades, covering different brands such as AlV40, AlV45, and AlV50, involving more than 10 kinds of test elements
.
Based on the principle of testing methods first and technical performance indicators moderately ahead of the current product status, Panzhihua Iron and Steel and Metallurgical Standards Institute have established a system for the determination of the chemical composition of vanadium aluminum alloy and ferrous metallurgy industry standards, solving the domestic lack of vanadium aluminum alloy composition analysis methods and standardizing them Regulations and other issues have filled the gaps in domestic standards, and created technical conditions and technical support for strictly regulating domestic and foreign trade of vanadium-aluminum alloy products, guiding enterprise production, and product quality supervision and inspection
.
These six vanadium aluminum alloy industry standards have gone through 6 years from the establishment of the project to the release and implementation.
They are the precipitation and experience summary of Panzhihua's quality control technology for many years
.
They are of great significance for promoting the standardization of China's product management and enhancing the competitiveness of the industry .
