《GB/T 1301-2008凿岩钎杆用中空钢》由TC183(全国钢标准化技术委员会)归口,TC183SC8(全国钢标准化技术委员会型钢分会)执行,主管部门为中国钢铁工业协会。
本标准修改采用ISO 722:1991《凿岩钎具――钎杆用六角形和圆形中空钢钢材》(英文版)。
本标准根据ISO 722:1991重新起草,根据我国凿岩钎杆用空钢生产的实际情况,本标准在采用国际标准时进行了修改。这些技术性差异主要如下:
――增加了技术要求、试验方法、检验规则、包装、标准和质量证明书等相应内容;
――六角形中空钢公称尺寸删除38、45,增加35的规格;
――圆形中空钢增加R39-、R46-、R52-的规格;
――基本尺寸的允许偏差分为两个级别,ISO 722只有一个级别。
本标准代替GB/T 1301-1994《凿岩钎杆用中空钢》。
本标准规定了凿岩钎杆用六角形和圆形中空钢的分类及代号、尺寸、外形及允许偏差、技术要求、试验方法、检验规则、包装、标志和质量证明书。
本标准适用于凿岩钎杆用六角形和圆形中空钢。
本标准与GB/T 1301-1994相比主要变化如下:
――调整了分类及代号部分相应内容;
――改变了凿岩钎杆用中空钢的代号,将原六角形代号B改为H、圆形代号D改为R;
――用公称尺寸数值表示规格代号;
――调整了尺寸、外形及允许偏差部分;
――增加了牌号ZK95CrMo、ZK40SiMnCrNiMo、ZK23CrNi3Mo、ZK22SiMnCrNi2Mo,删除了ZKT8;
――增加了低倍组织的要求;
――加严了弯曲度、硬度、脱碳层的要求;
――增加了包装、标志和质量证明书的相应内容。
