Three of the great benefits of vacuum heat treatment are:

• Parts emerge ready for further forming
• Parts emerge without scaling or discoloration
• Parts require no further cleaning

It takes a vacuum heat treatment furnace to achieve these results. Essentially, parts are positioned in a special chamber. Oxygen is removed from the chamber and replaced with (usually) argon gas. The chamber is heated to up to 2400 degrees F. rapidly, and then the temperature is lowered. “Soak” time depends on the “recipe” for the part and the particular material it is made of. A vacuum heat treatment cycle can take up to three hours. The process is computer controlled to insure uniformity and repeatability. Read the rest of this entry »

Jones Metal Products is a premier vacuum heat treatment facility, working to produce parts with excellent surface finishes and no discoloration or contamination due to oxidation.

Vacuum heat treating is ideal for ferrous metals such as:

• Bronze
• Steel
• Titanium Alloys
• Brass

Because a vacuum heat treatment oven operates with a complete absence of air and other gases, heat transfer through convection is prevented. Vacuum heat treating ensures that the parts being produced are not discolored or contaminated due to oxidation by burning off a fine layer of material from the surface of the part. As a result, parts that were vacuum heat treated are known for their excellent surface finishes.
