API 5L X52 (L360) steel plate features

API 5L X52 (L360) steel plate is a specific grade of pipeline steel produced according to API 5L standard. "API" stands for American Petroleum Institute, and "5L" stands for pipeline steel pipe code. X52 is a pressure grade for this steel plate, indicating that its minimum yield strength is 360MPa (i.e. L360).

API 5L X52 (L360) steel plate features:

High strength: API 5L X52 (L360) steel plates have high yield strength and tensile strength and can withstand high pressures.

Good toughness: the steel plate has good impact toughness and ductility, which can maintain stable performance in low temperature environment and avoid brittle fracture caused by temperature change.

Excellent corrosion resistance: Specially treated API 5L X52 (L360) steel plate has good corrosion resistance and can operate stably in harsh environments such as wet and corrosive media for a long time.

Reliable connection performance: The use of advanced welding technology and connection process to ensure that the pipeline connection is firm, good sealing, effectively prevent leakage and safety accidents.
