Alloy steel pit annealing furnace This furnace is suitable for hardware products and special steel enterprises to produce high-quality special products. After furnace spheroidizing and annealing, carbon tool steel, alloy tool steel, bearing steel, etc. achieve the required mechanical properties, physical properties, and improve Plasticity. Reduce residual stress, improve the uniformity of organization and composition. The processed product has no oxidation and decarburization, uniform spheroidization structure, and obtains good process performance and use performance. The mechanical properties of the steel after heat treatment can fully meet user requirements through material analysis, metallographic analysis, discussion of the spheroidization mechanism, and traceability of the spheroidization process.
