Heat Treatment
Technical expertise to give customers material properties they need
MetalTek’s depth of experience in austenitizing, quenching, tempering, and annealing over hundreds of alloy grades help us meet customer specifications. This heat treatment expertise combined with our metallurgy capabilities allows MetalTek to deliver the specific material properties that our customers need.
We offer computer-controlled oil, water, and air quench at multiple locations, with certifications including Nadcap and AMS 2750. Heat treatment capabilities are available up to 2,250°F (1,232°C) or more in a range of dimensions up to more than 37’ (11 m) in length.
If you have a material properties or performance issue to discuss, talk to a MetalTek metallurgist. MetalTek has the technical capabilities and expertise to satisfy your exact material requirements.

Vacuum Heat Treatment
Heat treating in a high-temperature vacuum furnace prevents adverse effects such as discoloration that occur due to the presence of oxygen. In vacuum heat treatment, air (and oxygen) is removed from the furnace to create a vacuum. The part may be heated in the vacuum with or without an inert gas (typically Argon) to achieve the desired properties while protecting the part’s surface. As in traditional heat treatment, the metal is quickly cooled. Advantages of vacuum heat treatment include improved material strength, high thermal efficiency, and no oxidation, decarburization, or carburization.
MetalTek has a maximum vacuum heat treatment capacity of 31 cubic feet (0.87 cubic meters) and a maximum heating temperature of 2,400°F (1,315°C). Typical stainless-steel alloys used in vacuum heat treatment include 17-4 PH, Inconel 625, and MTEK M152.
