ASTM A871-65 is a high strength low-alloy structural steel plate with atmospheric corrosion resistance. This specification provides for a 65ksi minimum yield strength and an 80ksi minimum tensile strength plus the atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon steels with our without copper addition. When properly exposed to the atmosphere, this steel can be used bare (unpainted) for many applications. The primary application for A871-65 is transmission and lighting poles as an aesthetically pleasing alternative to a galvanized structure.
