Heat Treating

Heat treating is often used to alter the physical properties of a material. Heat treatment is most frequently used to increase a materials ductility and reduce its hardness. Due to the very high temperatures used in the heat treat process even small amounts of oxygen, < 1ppm, will have detrimental oxidation affects on the parts being treated. Hydrogen gas generators supply hydrogen gas as needed to reduce the oxygen concentrations in the treatment atmosphere.
