Vacuum Heat Treating

Precise temperature control for heat treatment of complex alloys.

Some of the biggest names in manufacturing – including General Motors – trust Paulo’s Vacuum Heat Treating range of heat treating services. Our computer-controlled vacuum heat treating ensures consistent temperatures and other key variables, ensuring reliable results and uniformity across even the largest lot of parts. Our PICS software tracks and documents every variable across your entire projects, including thermocouple data and furnace cycle reports.

We also offer fast, controlled cooling on large cross sections with high-pressure multi-gas quenching, increasing ductility, improving die life and reducing heat checking.

We have multiple large-capacity vacuum furnaces with a variety of quench gases including nitrogen, argon, helium and hydrogen.

We offer a wide range of vacuum services, including:

  • Hardening
  • Annealing
  • Pressure Quenching
  • Tempering

Our vacuum heat treat furnaces can handle:

  • Rings up to 60” OD
  • Parts up to 50” high and 72” long
  • 20-bar rapid quenching
  • Up to 8,000-pound loads
