What is the material of L390
L390 is a high-performance pipeline steel plate that is mainly used for pipeline transport in the oil and gas industry. This material has the following characteristics:
Chemical composition: The chemical composition of L390 is strictly controlled, including carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulphur (S), etc., and may contain traces of alloying elements such as vanadium (V), niobium (Nb) and titanium (Ti).
Mechanical Properties: L390 steel plate is known for its excellent mechanical properties, as evidenced by yield strength ≥ 390MPa and tensile strength ≥ 490MPa. In addition, it has good elongation, ≥ 18%, showing good ductility.
Delivery state: L390 steel plate can be delivered in a variety of ways, including hot rolled, normalised, normalised rolled and thermo-mechanically rolled (TMCP) states, to suit different processing needs and scenarios.
Application areas: Due to its excellent mechanical properties and corrosion resistance, L390 steel plate has a wide range of application prospects in the field of pipeline transmission, such as oil and natural gas, and is also used in the manufacture of a variety of pressure vessels, heat exchangers and other equipment.
Overall, L390 is a high-performance pipeline steel plate for the oil and gas industry that requires high mechanical properties and corrosion resistance.
