Heat Treating

The same piece of metal can be soft and malleable, resilient and springy or hard enough to carve stone. Those properties are tuned by carefully controlled heating and quenching. The longevity and dependability of our firearms are due, in part, to our heat treating facilities and skills.

Our capabilities include:

  • Annealing
  • Hardening
  • Austempering
  • Normalizing
  • Aging
  • Bright hardening
  • Cryogenic freezing
  • Precipitation hardening
  • Brazing
  • Carburizing
  • Case hardening
  • Bright annealing
  • Stress relieving

We offer a variety of controlled quenching atmosphere processes, including: 

  • Oil
  • Nitrogen
  • Vacuum
  • Salt
  • Water

Most hardness requirements can be verified right in our inspection area. More critical parameters — from superficial Rockwell hardness to tensile testing — are verified in our in-house Metallurgy Lab.
