ISO 3183 PSL2 Grade X80M Introduce
ISO 3183 PSL2 Grade X80M 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 dimensions, mechanical properties, production techniques, and quality assurance processes. The standard also lays out how steel pipes are meant to be designed and manufactured, to help ensure that they are safe and reliable for their intended purpose.
Smelting temperature:1235°C - 1896°C
Application:Petroleum and natural gas industries -- Steel pipe for pipeline transportation systems
ISO 3183 PSL2 Grade X80M Material Mechanical Properties
The mechanical properties of ISO 3183 PSL2 Grade X80M are determined through the combination of chemistry, heat treatment, and mechanical processing. Generally speaking, the mechanical properties of ISO 3183 PSL2 Grade X80M can be improved by increasing the levels of alloying elements, such as carbon and manganese. ISO 3183 PSL2 Grade X80M 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 X80M has excellent weldability and is suitable for cold forming and bending.
The mechanical properties of the ISO 3183 PSL2 Grade X80M steel are as follows:
