More information

  • Product Details

    EN 10207 is a European standard outlining the specifications for steel used in simple pressure vessels. These vessels, defined as welded containers designed to withstand internal pressure exceeding 0.5 bar and intended for air or nitrogen (excluding fired pressure vessels), require robust materials.

    EN 10207 P265S falls under this category, boasting a minimum yield strength of 265 MPa (265 N/mm²). This high strength steel plate also possesses specific mechanical properties for elevated temperatures and is delivered in a normalised condition or an equivalent achieved through normalised rolling.

  • Key Advantages

    • High-Strength Performance: The minimum yield strength of 265 MPa makes EN 10207 P265S ideal for various simple pressure vessel applications.
    • Proven Weldability: This boiler plate steel offers excellent weldability, ensuring strong and dependable vessel construction.
    • Versatile Applications: EN 10207 P265S caters to a wide range of simple pressure vessel uses across various industries.
    • Extensive Stock Availability: Brown McFarlane maintains a substantial stock of EN 10207 P265S steel plates, guaranteeing prompt delivery to meet your project timelines.
