Pipeline steel L485

The method of expressing the grade of L485 pipeline steel:
L: represents the first letter of the transmission pipeline Line
485: Represents the specified yield strength value of the steel plate

Pipeline steel refers to large-diameter welded steel pipes used to transport oil, natural gas, etc. for hot-rolled coils or wide and thick plates.

During the use of pipeline steel, in addition to high compressive strength, it is also required to have high low temperature toughness and excellent welding performance.

Steel plates for oil and gas pipelines: x42(l290) x46(l320) x52(l360) x56 (l390) x60(l415) x65(l450) x70(l485) x80

L485 chemical composition:

C	Si	Mn	P	S
≤0.26	-	≤1.65	≤0.03	≤0.03

L485 mechanical performance requirements:
Tensile strength (MPa): 485
Yield strength (MPa): ≥570

L485 delivery status
L485/X70 steel plates shall be delivered in the state of hot rolling, normalizing, normalizing rolling and thermomechanical rolling
