Heat treatments are essential for ensuring high-quality metal and alloy products. Endothermic gas (CO/H2/N2) is often used as a ‘neutral’ protective gas or carrier gas during heat treatment processes. Monitoring and controlling the furnace gas composition is essential to ensure metallic products retain their desired properties.
Edinburgh Sensors outlined to gasworld in an interview why CO and CO2 levels must be precisely controlled and explained the best way to measure CO and CO2 concentrations in endothermic heat treatment furnaces.
Heat treatments are commonly used to alter the physical or chemical properties of materials such as metals and alloys, including steel. Heat treatments result in changes in material microstructures that provide increased hardness, temperature resistance, ductility, and strength.
