《GB/T 14841-2008钽及钽合金棒材》由TC243(全国有色金属标准化技术委员会)归口,TC243SC3(全国有色金属标准化技术委员会稀有金属分会)执行,主管部门为中国有色金属工业协会。
本标准规定了钽及钽合金棒材的要求、试验方法、检验规则和标志、包装、运输、贮存及订货单内容。本标准适用于铸锭或粉冶条坯经挤压、锻造、轧制、拉伸等工艺生产的钽及钽合金圆棒和方棒。 本标准代替GB/T14841―1993《钽及钽合金棒材》。
本标准修订时参照了美国ASTM B365:1998(2004确认)《钽及钽合金棒、丝材规范》。
本标准与GB/T14841―1993相比,主要有以下变动:
―――增加了拉伸生产工艺及相关要求;
―――表1中删除了“制造方法”一栏,将供货状态规定为冷加工态、热加工态和退火态,对棒材的长度(除锻制棒外)只规定了下限要求;
―――增加了TaNb40、TaW2.5和TaW10合金牌号及相关要求;
―――Ta1、Ta2、TaNb3、TaNb20、TaNb40、TaW2.5、TaW10直径或边长扩大到95mm;FTa1、FTa2直径或边长扩大到25mm;
―――删除了制造方法与规格之间的对应关系;
―――增加了检验结果的判定;
―――增加了订货单内容。


Scope
