ISO 3183 PSL2 Grade L360NS Introduce
In addition to these technical specifications, The ISO 3183 also lays out the required materials and production processes for making steel pipes. This includes information about the melting and forming processes, welding methods, and heat treatment for the pipe. All of this knowledge helps ensure that steel pipes are manufactured according to their design specifications.
Smelting temperature:1519°C - 1171°C
Application:Petroleum and natural gas industries -- Steel pipe for pipeline transportation systems
ISO 3183 PSL2 Grade L360NS Material Mechanical Properties
ISO 3183 PSL2 Grade L360NS 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 L360NS Material Machining Technology
The first step in machining ISO 3183 PSL2 Grade L360NS is to choose the correct cutting tool and machining setup. In order to achieve an adequate cutting speed, tools with a high number of cutting edges should be selected, preferably between 7000 and 12000 RPM. To reduce the risk of chip formation and tool wear, hard-faced cutting tools with a certain degree of flexibility should be used.
