L415 line pipe

L415 is the grade in the GB/T 9711-2011 standard and is a pipeline steel.

L is the meaning of line, which means pipeline, and 415 represents the yield strength of this steel.
That is, the yield strength of L415 is 415MPa.

X60 is equivalent to L415 steel plate material.

L415 steel plate, the wide and thick steel plate with a thickness of 6mm~40mm for oil and gas transmission longitudinal welded pipes and other fluid transmission longitudinal welded pipes.

Chemical composition of L415 pipeline steel:
C:0.12
Si:0.4
Mn:1.65
P: 0.02
S:0.01

L415 is mainly used for gas, water and oil transportation in the natural gas industry. The delivery state of the steel plate is hot rolling or controlled rolling.
