Heat Treatment

Technical expertise to give customers material properties they need

MetalTek’s depth of experience in austenitizing, quenching, tempering, annealing, and case hardening 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, MIL-H-6875, 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

Oxygen can cause undesirable properties such as discoloration.  Heat treating in a high-temperature vacuum furnace removes these properties.  An inert gas (typically Argon) replaces oxygen, and the part is heated to achieve the desired material properties.  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, decarbonization, or carbon.

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.
