ISO 3183 PSL2 Grade X46MO Introduce
ISO 3183 PSL2 Grade X46MO 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:1285°C - 1139°C
Application:Petroleum and natural gas industries -- Steel pipe for pipeline transportation systems
ISO 3183 PSL2 Grade X46MO Material Mechanical Properties
ISO 3183 PSL2 Grade X46MO 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.
