More information

Brown McFarlane specialises in chrome moly plates
o Intended primarily for use in the fabrication of process equipment designed for elevated temperature service.
o Chrome moly is the most common name for this group but other names that are used include chromalloy, croalloy, and Cr-Mo (pronounced “cro-mo”).

  • Chrome Moly Plates.

    While there are various Chromium Molybdenum steel products with distinct chemical and mechanical properties, they are often categorised as a single group.
    Brown McFarlane offers Chrome Moly plates manufactured according to the following standards: ASME SA387, ASTM A387, and EN10028-2.

  • Benefits of Chromium and Molybdenum in Steel

    Adding chromium and molybdenum to steel enhances its properties, making it ideal for high-temperature applications:

    Improved High-Temperature Strength

    Chrome Moly plates maintain exceptional strength even at elevated temperatures.

    Enhanced Creep Resistance

    Molybdenum specifically improves the steel’s ability to resist creep deformation under high temperature and stress.

    Superior Harden-ability

    Chrome Moly allows for deeper hardening, leading to increased overall strength.

    Additional Benefits

    Chrome Moly also offers improved wear resistance, corrosion resistance and impact resistance, while remaining relatively easy to fabricate.

    Meets leading international specifications

    Our Chrome Moly plates adhere to strict quality standards, including ASTM/ASME SA/A 387 (Gr. 5 Cl. 2, Gr. 11 Cl. 2, Gr. 12 Cl. 2, Gr. 22 Cl. 2) and BS EN 10028-2 (16Mo3, 13 CrMo Si 5-5, 13 CrMo 4-5, 10 CrMo 9-10).
