Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 2967-2008 "Casting tungsten carbide powder."
This standard compared with GB/T 2967-2008, the main changes are as follows.
--- Increasing the normative references;
--- Modify the product classification and grades;
--- Increased spherical casting tungsten carbide powder and its performance requirements;
--- Modify the product size range representation;
--- Modify the chemical composition of the product;
--- Increasing the product Vickers hardness, liquidity requirements;
--- Remove the contents of tube products;
--- Removed the content of high-carbon casting tungsten carbide powder.
This standard is proposed by China Nonferrous Metals Industry Association.
This standard by the National Non-ferrous Metal Standardization Technical Committee (SAC/TC243) centralized.
This standard is drafted by. Zigong Great Wall Hard Surface Materials Co., Ltd., Xiamen Jinlu Special Alloy Co., Ltd., Guangzhou Nonferrous Metal Research Institute
Institute, Institute of Non-ferrous Metal Technology Economics.
The main drafters of this standard. Li Wei, Yu Wei, Li Yuxi, Zhang Shouquan, Tan Lixin, Liu Xin, Wu Yanhua.
This standard replaces the standards previously issued as.
--- GB/T 2967-1982, GB/T 2967-1989, GB/T 2967-2008.
