Sinter-Hardened Powder Metal Steels

The sinter-hardened chemistry allows the material to harden during the cooling cycle of the sintering process. Advantages of using sinter-hardened powder metal parts include improved dimensional control, cleanliness, and reduction in the number of processing steps.

Sinter-hardened PM steels are used typically where high strength and wear resistance are required. These materials commonly show martensitic microstructures with regions of fine pearlite, bainite, and austenite.
