Foreword

At the time of revision of the American Standard reference ASTMB521.1998 (2004 confirmed), combined with domestic production and actual. This standard replaces GB/T 8182-1987 "tantalum and tantalum alloy seamless." This standard compared with GB/T 8182-1987, mainly in the following changes. --- Increased TaW2.5 alloy grades and requirements; --- Pipe diameter range expanded to 1mm ~ 65mm, and increases the relevant indicators; --- Modify the cut oblique volume index; --- Increasing the test results to determine; --- Increased orders (or contract) content. The standard proposed by China Nonferrous Metals Industry Association. This standard Nonferrous Metals by the National Standardization Technical Committee. This standard by the Baoji Titanium Group Ltd., Baoji Titanium Industry Co., Ltd. and Ningxia Orient Tantalum Industry Co., Ltd. is responsible for drafting. The main drafters of this standard. Wang Yongmei, Huang Yongguang, Li Nong, Wang Weiqi, learn Tong Wen, Huohong Feng, Li Ji Hyun. This standard replaces the standards previously issued as follows. --- GB/T 8182-1987.
