原国家质量技术监督局质技监标函[2000]171号文批准了冶金工业局上报的GB6654—1996《压力容器用钢板》第2号修改单(第2号修改单附后,下称修改单),自2001年1月1日实施。修改单的主要内容是降低了钢中的磷、硫含量和将冲击试验的温度从20℃改为0℃。笔者认为通过上述二项的修改,标志着我国压力容器用钢板的质量上了一个台阶。本文以应用最广泛的压力容器用16MnR钢板进行分析讨论:
The former State Quality and Technical Supervision Quality and Technical Supervision letter [2000] No. 171 approved the Metallurgical Industry Bureau reported GB6654-1996 “pressure vessel steel plate” No. 2 (single No. 2 attached, the following amendments Single), since January 1, 2001 implementation. The main content of the amendment is to reduce the phosphorus in the steel, sulfur content and the impact test temperature from 20 ℃ to 0 ℃. The author believes that through the above two changes, marking the quality of China’s pressure vessel steel on a higher level. In this paper, the most widely used pressure vessel with 16MnR steel analysis and discussion:
