Hello,
after stainless steels are hardened by austenitizing, the following step would be tempering. What is the right designation of the tempering facility?
"Quenching and Tempering Plant" or "Tempering and Quenching Plant"? I always read "Q&T" , but the sequences of the tempering treatment acctually is tempering and then quenching...I am confused.
BTW: sorry for my english...

1. Heat to high temperature (austenitizing, > 800 C)
2. Quench in oil/water/etc (~ 25 to 100 C)
3. Heat to intermediate temperature (tempering, ~ 180 to 600 C)
4. Quench in oil (~ 25 to 50 C)
Standards such as ISO 15787 Technical product documentation — Heat-treated ferrous parts — Presentation and indications recommend the following:
The condition after heat-treatment shall be specified in words indicating the required condition, for example,
“quench hardened”, “quench hardened and tempered” or “nitrided”.
This is why industry has adopted the usual description of Quenching and Tempering, meaning quench hardened and tempered.

@TVP: I need to know the right identification name for the plant, which only involves step 3 and 4 (the martensitic stainless steel has already been harden). I saw a plant, which was offline and only for induction tempering with subsequent quenching (water).

- induction heating system with power supply, coil,
- cooling system with quench ring (spray, shower, etc), integral tank, and heat exchanger
- material handling with robots or conveyor line or ...

In high production a quench is most common just for speed.
It is rare for the cooling rate from temper to have significant impact on the properties.
