1) ratio of intensity and yield strength
强屈比
1.
The research is done to the development of B400SD and B500SD reinforced bar in Cheng Steel according to the standard of UNE36065EX,the idea to solve the key problem-ratio of intensity and yield strength proposed as well as chemical composition design and controlled cooling measures in rolling.
对承钢开发符合UNE36065EX标准的B400SD和B500SD螺纹钢筋进行了研究,提出了解决强屈比这一关键问题的思路、化学成分设计和轧制控冷措施。
