SCC Behaviour of X-70 Pipeline Steel in Near-Neutral pH Solutions

Hao GUO , Guangfu LI , Xun CAI , Jianjiang ZHOU , Wu YANG

材料科学技术(英文)

The stress corrosion cracking (SCC) behaviour of X-70 pipeline steel in near-neutral pH solutions was studied $via$ slow strain rate testing (SSRT). The results showed that the cracking mode of X-70 pipeline steel in near-neutral pH solutions was transgranular at different temperatures and applied p...

Effect of Cyclic Loading on Cracking Behaviour of X-70 Pipeline Steel in Near-Neutral pH Solutions

Hao GUO , Guangfu LI , Xun CAI , Ruipeng YANG , Wu YANG

材料科学技术(英文)

The cracking behaviour of X-70 pipeline steel in near-neutral pH solutions was studied under different modes of cyclic loading. The crack propagation process of X-70 pipeline steel under low frequency cyclic loading condition was controlled mainly by stress corrosion cracking (SCC) mechanism. Under ...

Processing of Ultralow Carbon Pipeline Steels with Acicular Ferrite

Furen XIAO , Mingchun ZHAO , Yiyin SHAN , Bo LIAO , Ke YANG

材料科学技术(英文)

Acicular ferrite microstructure was achieved for an ultralow carbon pipeline steel through the improved thermomechanical control process (TMCP), which was based on the transformation process of deformed austenite of steel. Compared with commercial pipeline steels, the experimental ultralow carbon pi...
