| Abstract: | The development of pipeline steel in Baosteel is briefly reviewed. The pipeline steels with high strength and high toughness, HIC resistance and heavy gauge X70 with acicular ferrite and larger diameter have been studied and developed in Baos t eel. The compositions and processing of series X pipeline steels have been grad ua lly established in Baosteel. The quality of the steel is stable. The products ha ve been applied in both domestic and oversea pipeline projects such as West ea s t pipeline project ,Zhong Wu gas pipeline project and Turkish gas pipeline pro ject and so on. |
