ISO 3183 PSL2 Grade X60NE Introduce
The ISO 3183 also defines in detail the quality assurance processes that need to be followed during the production and assembly of steel pipes. This includes the testing of pipes for strength and hardness, as well as the use of NDT (non-destructive testing) methods to detect any manufacturing defects. All of these tests and inspections help to ensure that any steel pipes that are produced are fit for their intended use.

ISO 3183 PSL2 Grade X60NE Material Mechanical Properties
The mechanical properties of ISO 3183 PSL2 Grade X60NE are determined through the combination of chemistry, heat treatment, and mechanical processing. Generally speaking, the mechanical properties of ISO 3183 PSL2 Grade X60NE can be improved by increasing the levels of alloying elements, such as carbon and manganese. ISO 3183 PSL2 Grade X60NE 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 X60NE has excellent weldability and is suitable for cold forming and bending.
The mechanical properties of the ISO 3183 PSL2 Grade X60NE steel are as follows:
