摘要
采用示波冲击法研究了9Cr-1Mo-V-Nb-N钢厚壁无缝管研制品供货状态下的动力强韧性,并与住友91钢管进行了比较,结果显示,研制管高温时的韧性已与住友管没有差别,但室温时的韧性仍有差距.
The dynamic strength and toughness of seamless 9Cr-lMo-V-Nb-N thick-walled pipes were investigated by means of oscilloscope charpy impact tests. The results show that the toughness under high temperature is almost the same as those made by Sumitomo Metal Industries Ltd, but the toughness under room temperature is worse.
