Relationship between coercive force and stress of X80 pipeline steel
Journal of Physics: Conference SeriesAbstract X80 pipeline steel is widely used in long-distance oil and gas transportation due to its high strength and toughness. However, reducing wall thickness to cut costs can lead to stress concentration during forming and under external loads.
