GB19189—2011《压力容器用调质高强度钢板》标准研究

Development of GB 19189-2011 ＂Quenched and tempered high strength steel plates for pressure vessels＂

简要介绍了GB19189—2011标准中4种铜板的特性、主要技术指标及其应用情况。与国外先进水平标准相比较，我国GB19189标准的主要技术指标优于国际标准，特别是钢板冲击功指标的确定，考虑了容器制造工艺过程对钢板性能的影响。先进合理的技术指标为容器向大型化发展和安全使用奠定了基础。

This article briefly introduced the performance, main technical indexes and the application state of the four steel grades specified in the standard of GB 19189-2011. Compared with the foreign advanced standards, the main technical indexes of GB 19189-2011 are superior to international standards, especially the impact energy index determine, it took the effect of vessel manufacturing process on steel performance into account. Advanced and reasonable technical indexes laid the foundation for large scale development and security application of pressure vessels.
