Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. Instead of the standard YS/T 579-2006 "vanadium aluminum master alloy." This standard YS/T 579-2006 compared to the main changes are as follows. --- Increased requirements N elements; --- Of Fe, C, O, Si element content has been adjusted; --- On size range has been adjusted; --- Increase the surface of the nitride requirements; --- Adjust the high density inclusions inspection requirements; --- Of inspection rules were revised. This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized. This standard is drafted by. Baoji Titanium Group Co., Ltd. Dalian Rong Gaudet kinds of materials, Chengde Vanadium big public limited liability Secretary, Baoji Titanium Industry Co., Ltd., Baoji Titanium Special Metals Co.. The main drafters of this standard. Robin Li Fengjun Ning, Mao Lingling, Liu Zhiguang, Sui Yingdan, Liu, Wang Chang Jian, Rong Yang, Liu Min, Lixian Jun. This standard replaces the standards previously issued as follows. --- YS/T 579-2006. Vanadium aluminum master alloys

1 Scope

This standard specifies requirements for vanadium aluminum master alloy, test methods, inspection rules, marking, packaging, transportation, storage and quality certificate hehe Same (or orders) content. This standard applies to the use of hot metal produced by reduction of vanadium aluminum master alloy (hereinafter referred to as the product). The titanium alloy can be used as high Temperature alloys and other special alloys additives.
