Increasing the steel grade and gas pressure in pipeline project means the crack arrest toughness for pipe needs to enhance greatly. In this paper, effect factors of X80 toughness were studied. Through commercial production of X80 steel, it was found that the content of carbon or sulphur influenced impact energy obviously. Large numbers of statistical data showed that impact energy would well satisfy...
