Stress Relieving

To your specifications, we stress relieve anything from small parts to fabrications 15 feet wide by 40 feet long.

Normalizing

From small parts right up to big foundry castings and flame cut profiled plates to 15 feet by 40 feet.

Normalizing Furnace-50 000lbs of profiled plates

Annealing

Tool steels, profiled plates, castings, and fabrications, from small parts to large pieces up to 15 feet by 40 feet.

Solution Annealing

Higher temperature annealing capabilities allow us to treat your high-alloy and exotic stainless steel parts.

Cryogenic Treatment

With temperatures controlled to -320˚F, deep freezing provides stress relieving and enhances wear properties of tool steels, extending tool life.  Re-treating by this method also extends the service life of punches and dies.

Our cryogenic treatment capacity can handle small pieces and parts up to 4 feet by 4 feet by 4 feet.
