New Low-Carbon Steel for Hot, Warm, or Cold Forging

The development of a new high-strength steel started from the needs of cold forging and continued into hot- and warm-forging areas. The steel has a very low carbon content (< 0.1 % C) and chromium–boron alloying. Its hardening is simple: just water quenching without tempering. Hot forgings of this steel are directly quenched from forging temperature, resulting in process cost savings and weight reduction.
