Established in 1962, we are a specialty heat treating and brazing facility located in Cranston, RI.
Let Spectrum review your needs; using capabilities designed to add value to your work.
Many processes require cold processing. At Spectrum Thermal Processing we don't just handle the hot thermal processes, we also have a suite of sub-zero treatments as well. Deep freeze operations take parts down as low as -120°F to enhance microstructure stability. For more extreme processes we support cryogenic freezing in liquid nitrogen down to -373°F.Learn More about Deep Freeze, Cryo Freeze
We can help with assembling and fixturing requirements for your parts. This department also includes three bell type furnaces for aging, tempering, low temperature brazing and soldering. Numerous air furnaces and a deep freeze unit round out the department.Learn More about Hardening, Annealing, Aging
Spectrum can improve the surface performance of steel components by gas Nitriding or Low Pressure Vacuum Carburizing. Spectrum can also ferritic nitrocarburize. We have invested considerable resources in developing these processes and are intimately familiar with how to manipulate the processing parameters to achieve your quality requirements.Learn More about Surface Enhancement: Vacuum Carburizing, Gas Nitriding
