Sinter Furnace Hardening

In addition to standard heat-treat processes, GKN offers sinter furnace hardening (SFH). SFH involves selective alloying of the P/M materials so that a strong, hard microstructure is developed during a fast cooling stage in the sintering process. Benefits include:

Cost and time savings
Dimensional control
Shape retention
Readily impregnated
Improved appearance
