Sinter hardening is a manufacturing process used in powder metallurgy. It involves rapidly cooling powdered metal parts after the sintering process. This unique approach allows the material to harden during the cooling phase, presenting several advantages, including improved dimensional control and a reduction in processing steps. The hardness of sinter-hardened components can reach HRC30~40 or even higher after sintering. Sinter hardening distinguishes itself by combining the advantages of both sintering and hardening in a single operation. This approach minimizes the need for additional hardening operations. It also enhances hardness and accuracy.

Sintered hardened parts are components that compress metal powder into the desired shape and then heat the compacted powder into a solid, usually used to make gears, firearms, locking systems, actuators, bearing houses, and more. The superior strength and hardness of sinter-hardened parts make them exceptional performers in various industries.
