PM steels containing Fe-Mo, Fe-Cr-Ho-Co powder hard particles have been used for engine valve seat inserts. Possibility on replacement of the Fe-Ho, Fe-Cr-Mo-Co powder particles with high speed steel powder particles of M3/2 and M42, were examined in order to improve properties of the above PM steels. The results obtained were summarised as follows. 1) Addition of M3/2 and M42 powder particles is effective for strength up to 5wt%, however over 5wt% addition is harmful for strength. 2) PM steel contained M3/2 and M42 powder particles each 2wt% together showed best properties for wear.
