| Abstract: | Inclusion size and inclusion composition in X70 pipeline steel have been studied. Results show that there are some large inclusions such as silicate and SiO2 inclusions in X70 pipeline steel. The harm of silicate and SiO2 inclusions is analyzed. Measurements are put forward to avoid silicate and SiO2 inclusions. Good results have been obtained. |
