After steel is formed, it will undergo a series of processing techniques to generate stress, change the metallographic structure inside the steel, and affect the performance of the steel. Therefore, after many steel processes are processed, further heat treatment is required to improve the performance of the steel. Common processes include annealing, tempering, carburizing, nitriding, etc. J.Parker high temperature series burners can meet the requirements of different furnace types and achieve high-speed flame, medium-speed flame, flat flame, and flameless characteristics.
