Vacuum Heat Treat

ThermTech has four vacuum heat treat furnaces that are capable of running investment castings in both 300 series stainless steels and super-alloys for Vacuum Solution Annealing.  The advantages of running these investment castings in a vacuum is that the parts come out of the furnace with no scale and the parts can be quenched via a nitrogen quench versus a liquid quench which helps minimize distortion.  If you cast such parts as impellars or other items that have several internal surfaces in which cleanliness is important then vacuum solution annealing is the solution to internal cleanliness issues.
