    1. Scope

    1.1 This specification covers high-strength, low-alloy, hot- and cold-rolled sheet and strip in cut lengths or coils, intended for use in structural and miscellaneous purposes, where savings in weight or added durability are important. These steels have enhanced atmospheric corrosion resistance and are supplied in two types: Type 2 contains 0.20 minimum copper based on cast or heat analysis (0.18 minimum Cu for product check). Type 4 contains additional alloying elements and provides a level of corrosion resistance substantially better than that of carbon steels with or without copper addition (Note 1). When properly exposed to the atmosphere, Type 4 steel can be used bare (unpainted) for many applications.

    Note 1—For methods of establishing the atmospheric corrosion resistance of low-alloy steels, see Guide G 101.

    1.2 The values stated in inch-pound units are to be regarded as the standard.
