Water quench
Reserved for light alloyed steels, such as 1045, W1. As the cooling rate in water is very high, this treatment presents high risks of distortion, even of cracking.

Oil quench
Used for low-alloyed steels such as 1045, 4140, 4340, 8620, 9310, 52100 or tool steels like O1. Thermetco uses controlled atmosphere furnaces to guarantee optimum results without oxidation or decarburization.

Forced air quench
Performed mainly when a part's dimensions exceed the capacity of the vacuum furnaces. For example: Stainless steel 410, 420, 431 and tool steel H13.

Vacuum quench
Essentially used on tool steels (A2, D2 S7, H13, H21, T1, M2) and martensitic stainless steels (410, 420, 440C).

Thermetco's vacuum furnaces have cooling rates ranging from 1 to 10 bars using nitrogen and argon as the medium.

In addition to vacuum quenching, Thermetco can offer cryogenic and nitriding treatments.
