A871-65 is a high-strength low-alloy structural steel plate. It is used for tubular structures and poles. ASTM871-65 has atmospheric corrosion resistance so it can be used bare or unpainted for many applications. Two grades, 60 and 65, may be provided as-rolled, normalized or quenched and tempered as required to meet the specified mechanical requirements.
The atmospheric corrosion resistance of this ASTM871 in most environments is substantially better than that of carbon structural steels.
