APPLICATIONS
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.
FORGING
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.
MACHINABILITY
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.
WELDABILITY
These grades may be welded by all fusion methods.
