Analysis of pipeline steel X80
Pipeline steel X80 is high strength pipeline steel. Its minimum yield value (MPa) is 555. The yield value refers to the stress value of the material in the yield stage during tension, and the yield stress refers to the critical value from the yield stage to the shrinkage stage.
X represents pipeline steel in API Spec 5L, 80 is its strength level, and its unit is "kpsi". X80 represents pipeline steel whose minimum yield strength is 80kpsi, which is equivalent to 552 MPa in metric unit.
In China, L stands for pipeline steel. It is specified in GB / T 9711-2011 steel pipes for pipeline transportation system in petroleum and natural gas industries that L555 in China is equivalent to X80 in API Spec 5L.
Executive standards of pipeline steel X80: API 5L standard and special engineering standards.
Delivery status of pipeline steel X80: mainly in hot rolling and normalizing state.
Characteristics of pipeline steel X80:
Pipeline steel X80 has high strength, high toughness, good weldability, certain HIC and SSC resistance, etc.
