Some standard content:
GB/T3622-1999
This standard is a revision of GB/T3622-1983 "Titanium Strip". The writing format conforms to GB/T1.1993. This standard adds: a low-strength industrial pure titanium grade TAO and two corrosion-resistant alloy grades TA9 and TA10; increases the degree of evaluation deviation; divides the products into strips and foils, and adds annealed state supply for foils: the chemical composition is consistent with GB13/T3620.1199~-, and the provisions on the allowable deviation of the relevant composition are added; the mechanical properties are appropriately adjusted. AM2 is added, which is consistent with GB/T3621199.1 "Titanium and Titanium Alloys". The mechanical properties of TA10 alloy mainly refer to ASTMB265:1995 "Specifications for Titanium and Titanium Alloys, Sheets and Plates": This standard is consistent with the above standards in technical requirements, and the standard level has been greatly improved. From the date of implementation, this standard will replace GB/T3622-1983 at the same time. This standard was proposed by the State Bureau of Nonferrous Metals Industry. This standard is under the jurisdiction of the China Nonferrous Metals Industry Standard Metrology and Quality Research Institute. This standard was drafted by Baoji Nonferrous Metals Processing Plant. The main drafters of this standard are: Li Lin, Meng Qinglin, Zhang Yansheng, Ming Ke, Yang Lijuan. This standard was first issued in 1983.
