What are the main properties of API Spec 5L X80 steel?

X80 pipeline steel is mainly used in oil and gas pipelines. The first two X80 of the lower yield strength value is the line pipe small yield strength of 80000psi (552MPa).

Main properties of API Spec 5L X80 steel

X80 pipeline steel has high strength, high toughness, good weldability, certain resistance to HIC and SSC, and the improvement of pipeline steel grade can save construction costs.

X80 steel plate chemical element analysis

Pipeline steel Early pipeline steel has always used ordinary carbon steels of C, Mn, and Si types, which focused on performance in metallurgy and did not have strict regulations on chemical composition. Since 60 years, with the increase of oil and gas pipeline delivery pressure and pipe diameter, low-alloy high-strength steel (HSLA) has been adopted, mainly delivered in hot rolled and normalized conditions. X80 pipeline steel is mainly used in oil and gas pipelines.
