Low-Carbon Steels 1005-1008

General Characteristics

These are low-carbon steels that may be used in many forms, from deep drawing flat-rolled products up through forgings. Because of their inherent lack of strength they would on occasion be used in the carburized condition.

Applications of these steels will be limited to those parts where strength and wear resistance for example are not primary requirements. In the case of forgings, for example, the steels could be considered to be case-hardening types.


These are materials that are relatively easy to work with. They may be forged from a temperature of around 2400ºF (1315ºC), or some 300ºF (150ºC) below their solidus temperature.

Heat Treatment

These steels would not normally be annealed and may be machined in the as-rolled or as-forged conditions.

These steel grades are also used in flat-rolled form and in such cases may undergo some form of severe deformation – deep drawing for instance. In such cases special heat treatment cycles are used, which may involve continuous coil annealing.


Best machinability of these grades is normally obtained in the as-rolled or as-forged condition. If the parts are such that very different structures may obtain throughout the size of a part, then a normalizing treatment at around 1700ºF (925ºC) might be recommended.


These grades may be welded by all fusion methods.
