ASTM A714 Grade III seamless steel pipe/tube, high-strength low-alloy steels have enhanced resistance to general atmospheric corrosion by weathering as commonly encountered in rural, urban, marine, and industrial environments. A714 Grade III pipe are supplied in two classes: Class 2, having corrosion resistance equivalent to that of carbon A714 Grade III steel with copper (0.20 minimum Cu); and Class 4, having corrosion resistance substantially better than that of Class 2. Class 4 A714 Grade III steels when properly exposed to the atmosphere can be used bare (unpainted) for many applications.
