I don’t know how much you know about industrial sprocket, how much you know about the gas sputum process of industrial sprocket, the following editor will share with you on this issue: Process route: preheating 200°Cx2h-preheating 300°CX2h-pre-oxidizing 400°CX2h-exhaust uniform temperature 480-490°CX3h-nitriding, strong nitriding 480-490°CX50h, ammonia decomposition rate is about 20%- Diffusion 480-490°CX20h, the ammonia decomposition rate is about 25%-furnace cooled to below 150°C and air cooled. Nitriding results of industrial sprocket: the depth of the nitriding layer is 0.5mm, the tooth surface hardness is 688-713HV, the brittleness of the nitriding layer is level 1, and the surface structure is 0.01mm e-phase and vein-like nitrides close to the surface.
