    The ASTM A871 specification is the standard specification for high-strength low-alloy structural steel plates with atmospheric corrosion resistance used in tubular structures and poles.

    Product introduction
    The ASTM A871 specification is the standard specification for high-strength low-alloy structural steel plates with atmospheric corrosion resistance used in tubular structures and poles. Grades 60 and 65 are available in the as-rolled, normalized, or quenched and tempered delivery conditions as required to achieve the specified mechanical properties.

    The specifications:
    Thickness: 3mm--150mm
    Width: 30mm--4000mm
    Length: 1000mm--12000mm
    Standard: ASTM EN10025 JIS GB
    Technical Data
    A871 Grade 65 may be provided as-rolled, normalized or quenched and tempered.
