The mechanical properties of ISO 3183 PSL2 Grade X60M are determined through the combination of chemistry, heat treatment, and mechanical processing. Generally speaking, the mechanical properties of ISO 3183 PSL2 Grade X60M can be improved by increasing the levels of alloying elements, such as carbon and manganese. ISO 3183 PSL2 Grade X60M 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 X60M has excellent weldability and is suitable for cold forming and bending.

ISO 3183 PSL2 Grade L390N has a molecular structure that consists mostly of iron (Fe) atoms bonded to carbon (C) and other elements. Its melting point is around 1370-1400°C, making it a highly heat-resistant material. As a result, it is often used in applications that require high temperatures and superior thermal resistance.

The latest revision, ISO 3183:2018, was published in August 2018, replacing the original version of the standard. The goal of The ISO 3183 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. The standard provides guidance and detailed requirements for the design, production, and assembly of steel pipes, so that they will last for the duration of their intended use.

The thermal expansion of ISO 3183 PSL2 Grade L320MS is higher than many other steels. This means that when heated, its volume increases and when cooled, its volume decreases. The thermal expansion coefficient of ISO 3183 PSL2 Grade L320MS is 17.9 μm/m/°C at 20°C. Its coefficient of linear expansion is 4.4 × 10-6/°C.

ISO 3183 PSL2 Grade L360NO 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 L320QS has a higher thermal conductivity than other steels, with a value of 58.6 W/m⋅°C at 20°C. This allows it to conduct heat more efficiently than some other types of steel. As a result, it is often used in applications where a high heat transfer rate is desired.

The ISO 3183 provides detailed information on all technical aspects of steel pipes, including their dimensions, mechanical properties, and quality assurance requirements. For example, it sets out requirements for the strength, hardness, and longitudinal weld tests that need to be performed in order to ensure that the pipe is suitable for its intended purpose.

ISO 3183 PSL2 Grade L290R has excellent corrosion resistance, making it well-suited for use in many industrial applications. The corrosion resistance of the steel can be improved by low levels of sulfur and phosphorous, as well as by adding chromium and nickel to the alloying elements. The steel's ability to resist corrosion is also dependent on the surrounding environment. In a marine environment, for example, the alloy should be treated with additional corrosion inhibitors to improve its resistance to corrosion.

ISO 3183 PSL2 Grade X70ME has a higher thermal conductivity than other steels, with a value of 58.6 W/m⋅°C at 20°C. This allows it to conduct heat more efficiently than some other types of steel. As a result, it is often used in applications where a high heat transfer rate is desired.

ISO 3183 PSL2 Grade X46QS has a molecular structure that consists mostly of iron (Fe) atoms bonded to carbon (C) and other elements. Its melting point is around 1370-1400°C, making it a highly heat-resistant material. As a result, it is often used in applications that require high temperatures and superior thermal resistance.
