摘要

Steel that is used for strengthened parts in machines after forging and machining processes is higher in strength as the amount of carbon increases. However, its work- ability and machining are poor. This presents a problem for strengthening and proc- essing properties to co-exist in a steel product. Because we maintained the carbon in steel as graphite that easily deforms and made a matrix as a ferrite that is close to pure iron, we developed graphitic steel that is soft and has superior processing prop- erties despite having high carbon amounts.
