• A709 Grade 50 Steel Plate
  • A709 Grade 50 Steel Plate

    A high-strength, low-alloy structural steel plate utilized primarily in the manufacture of bridges. Chapel Steel stocks A709 Grade 36, A709 Grade 50 and A709 Grade 50W. These grades are often specified with Charpy tests referencing the specific zone or lowest anticipated service temperature. The Charpy tests are specified as non-fracture critical, which is a per-heat test (frequency "H"), or fracture critical, which is a per-plate test (Frequency "P"). Bridge steels can also be ordered to the ASSHTO M270 Specification referenced as AASHTO M270 Grade 36, AASHTO M270 Grade 50, AASHTO M270 Grade 50W.

    ASTM A709 steel plate is primarily used in the manufacture of bridges.
    Leeco Steel stocks A709 steel plate Grade 36, 50 and 50W. These grades are often specified with charpy tests referencing the specific zone, or climatic region, in which the bridge will be in use.
    Bridge steels can also be ordered to the AASHTO M270 spec referenced as AASHTO M270 Grade 36, AASHTO M270 Grade 50, AASHTO M270 Grade 50W. AASHTO is the abbreviation for American Association of State Highway and Transportation Officials
