High-density powder steel obtained with the technology of hot stamping of porous blanks is much inferior in terms of machinability by cutting similar cast and hot-rolled steels to the chemical composition. The paper considers the ways of possible improvement of machinability of structural powder steels.

Keywords: Powder metallurgy, hot forging of porous preforms, machinability by cutting
