《GB/T 15062-2008一般用途高温合金管》由TC183(全国钢标准化技术委员会)归口,TC183SC10(全国钢标准化技术委员会特殊合金分会)执行,主管部门为中国钢铁工业协会。
本标准规定了一般用途高温合金冷拔(扎)无缝管的尺寸、外形及允许偏差、技术要求、试验方法、检验规则等。本标准与GB/T 15062-1994相比,主要变化如下:
―――增加了GH3044、GH3536、GH4163等三个合金牌号化学成分、力学性能、硬度试验、压扁试验、扩口试验、晶粒度、超声波探伤和晶间腐蚀等内容;
―――增加了超声波探伤要求、晶粒度要求、扩口试验、液压试验和硬度要求;
―――将外径和壁厚允许偏差分成高级精度和普通精度;
―――修改了化学分析和取样方法的规定;
―――对复验规则进行了修改,更加明确、具体。
