The SLT steam treating mesh belt furnace is a continuous process unit that uses superheated steam at a working temperature of 560C to form a dense, blue black magnetite oxide layer on the surface and within the open porosity of powder metallurgy and ferrous parts. The steam treatment seals the surface, raises wear resistance, improves corrosion resistance and reduces friction, extending the service life of sintered bearings, gears and structural components.
