| 摘 要： | The fracture toughness of OS-F101 415F pipeline steel and its welded joint had been systematically studied. The present results suggest that OS-F101 415F pipeline steel and its welded joint all have relatively high fracture toughness values at 0℃, which are higher than 0.30 mm. The main reason for such results is the over 80% acicular ferrite in their mwrostructure
