ISO 3183 PSL2 Grade L390MO Introduce
ISO 3183 PSL2 Grade L390MO is an international standard that defines and categorizes the way steel pipes are used in the oil and gas industry. It covers both process and structural pipes and offers detailed information on pipe design and production, as well as quality assurance processes. The goal of the standard is to ensure that steel piping used in the oil and gas industry is safe, reliable, and compatible with the other components in the system.

ISO 3183 PSL2 Grade L390MO Material Mechanical Properties
The mechanical properties of ISO 3183 PSL2 Grade L390MO are determined through the combination of chemistry, heat treatment, and mechanical processing. Generally speaking, the mechanical properties of ISO 3183 PSL2 Grade L390MO can be improved by increasing the levels of alloying elements, such as carbon and manganese. ISO 3183 PSL2 Grade L390MO is often classified as a medium carbon steel with a yield strength of at least 250 MPa (36 ksi). It is also classified as an alloy steel, which means it has a higher level of strength than low carbon steel and greater wear resistance than stainless steel. Generally, ISO 3183 PSL2 Grade L390MO has excellent weldability and is suitable for cold forming and bending.
The mechanical properties of the ISO 3183 PSL2 Grade L390MO steel are as follows:
