What is Through Hardening / Quench & Temper?
Through hardening, also known as "quench & temper", is a process that consists of heating the parts to a temperature above the transformation range and then rapidly cooling to room temperature, usually using an oil quench. This may be performed in air or in a controlled atmosphere to protect the part's surface. Parts are then reheated to a lower temperature to temper to the desired final hardness range.
Benefits
- Improves strength and hardness
- Controllable specific mechanical properties
