Hermitage PA, July 27, 2026 – A new 11,000-gallon stainless steel recirculating water quench tank has been installed as preparations continue for the commissioning of our state-of-the-art titanium drop bottom water quench furnace.

The furnace remains on schedule to be fully commissioned and operational by September 2026.

Designed primarily to solution treat titanium bars, titanium forgings, and other large titanium components, the furnace features a 14-foot-long × 54-inch-wide × 48-inch-high workload envelope. Parts will be rapidly transferred into this 11,000-gallon recirculating and agitated water quench tank within a five to seven second time stamp, delivering the rapid and uniform cooling required to achieve consistent metallurgical properties for demanding aerospace, defense, and industrial applications.

This investment further expands 51����’ capabilities for processing large titanium components while reinforcing our commitment to providing advanced thermal processing solutions for the industry’s most critical applications.
