This paper presents the aspects of vacuum carburizing technology that have an impact on process costs and quality improvements in the final product. There is an interest in furnaces for vacuum carburizing due to the demand for products with overall metallurgical quality and low unit cost. Vacuum carburizing technology produces work with minimum distortion, and desired surface metallurgy. Systems can provide "cold to cold" (cold work going in, cold work coming out) and fully automatic operation that reduces operator involvement, thus minimizing labor. Considering upstream and downstream requirements, vacuum carburizing can provide a total reduction of costs. This technology differs considerably from traditional gas carburizing both in the equipment used and in the process economy.
