《GB/T 2967-2008铸造碳化钨粉》由TC243(全国有色金属标准化技术委员会)归口,TC243SC4(全国有色金属标准化技术委员会粉末冶金分会)执行,主管部门为中国有色金属工业协会。
本标准代替GB/T2967―1989《铸造碳化钨》。本标准规定了铸造碳化钨粉的要求、试验方法、检验规则与标志、包装、运输、贮存及订货单(或合同)内容。本标准适用于石油钻具、建材机械、甘蔗破碎刀具、粮食机械、造纸机械以及其他易磨损部件表面补强用的铸造碳化钨粉。本标准与GB/T2967―1989相比,主要有如下变动:
―――标准名称改成《铸造碳化钨粉》;
―――根据碳含量不同,增加了高碳铸造碳化钨粉;
―――修改了产品的化学成分;
―――根据粒度不同,将铸造碳化钨粉分为10个牌号,将高碳铸造碳化钨粉分为6个牌号;
―――增加了外观质量的要求;
―――增加了松装密度的规定;
―――增加了筛分检测方法;
―――增加了附录A。
