Welcome to Bayson Heat Treating


Below are some of the many services we currently offer:

Bright Hardening

Decrease a metal alloys ductility and increase it's hardness. A common method is to heat the material to well above it's recrystallization temperature and then quench it in a fluid such as oil, water or salt water.


In tool steels, cryogenic treatment can increase a materials strength and hardness as well as it's toughness and wear resistance. In conductive cables and electronics components cryogenics can improve conductivity.


A mixture of high pressure air and sand is sprayed over metal parts to clean them.

Vacuum Hardening

A vacuum furnace uses low atmospheric pressures instead of a protective gas atmosphere like most heat-treating furnaces. Metals treated in a Vacuum furnace experience less deformation and are much cleaner.
