API 5L Grade L450 pipe or X65 is a carbon steel pipe with a minimum yield of 450 MPa and tensile strength from 535 to 760 MPa. Its usual chemical content consists of carbon (up to 0.26%), manganese (1.20–1.40%), phosphorus (up to 0.030%), sulfur (up to 0.030%), and trace alloying constituents based on PSL1 or PSL2 grade. These pipes are highly weldable, tough, and resistant to mechanical stress and corrosion. L450 is capable for harsh service conditions, particularly where high pressure, long-distance transportation, and exposure to environment occur.
