介绍了独联体国家跨国标准GOST9454--1978《金属低温、室温和高温冲击弯曲试验方法》,并与我国现行的GB/T229--2007《金属材料夏比摆锤冲击试验方法》进行了比较。从两标准的适用范围、试样要求、设备要求、试验过程及试验结果评定等主要技术要求方面的对比看,两者在试样的类型尺寸、操作程序及结果表示等方面存在较大差异,...
• 冲击试验应符合GOST 9454-78的规定。 • 若屈服现象不明显且不能确定屈服应力σT(即σs)时,允许采用屈服极限σ0.2(即Rp0.2)。 • 热处理温度允许偏差:淬火 ±15°C;低温回火 ±30°C;高温回火 ±50°C 我要采购我能供货我要纠错
