API 5L X65 steel is a low-carbon steel.
API 5L X65 steel
In terms of chemistry, API 5L X65 steel is quite simple when compared to other specialized steels. API 5L X65 steel has a very low carbon content (0.10 percent) compared against other steels. Additional elements are also found in smaller quantities; silicon (0.35 percent), sulfur (0.005 percent), phosphorous (0.15 percent), and nitrogen at 0.015 percent. Manganese is the most abundant element --- after iron --- at 1.5 percent. Additionally, API 5L X65 steel has two exotic elements added as needed for specific applications. Vanadium and titanium both add toughness and are sometimes found in small quantities.
In terms of physical properties, API 5L X65 steel's most useful property for the pipe-fitting applications is its excellent weldability. API 5L X65 steel is quite tough, with a yield strength (the point at which the steel deforms under pressure) of 65 kilograms per square inch. The tensile strength (the point at which the material necks, or deforms radially) is 77 ksi. Other properties include a slight ability to be heat treated, but due to the low carbon content X65 cannot be tempered.
API 5L X65 steel is primarily used in the oil and gas industries as one of the primary steels used in pipe. The strength and low cost make API 5L X65 steel much more attractive than other, higher-performing steels since these industries routinely use miles of pipe. API 5L X65 steel strength also means it is a good choice for pressurized lines, where the steel's excellent weldabilty ensures strong seals.
