Nitriding treatment is mainly applicable to low carbon steel, medium carbon alloy structural steel, tool steel and die steel containing Cr, Mo, V, Ti, Al and other elements. After nitriding treatment, a strong and tough surface hardened layer can be obtained, the core structure of the steel can be improved, and the overall strength and toughness of the steel can be improved.
Vacuum nitriding is a chemical process in which the active gas N atoms are penetrated into the metal surface in a pulsed manner under low vacuum (thousands PA ~ tens of kPa) and low temperature, so as to obtain high surface hardness or corrosion resistance. It is a process means of combining vacuum heat treatment with gas nitriding.
Paijin vacuum nitriding furnace uses the most advanced pulse carburizing technology to achieve stable and efficient nitriding effect through vacuum strong pulse. The matching PE nitriding expert system can simulate the nitriding process offline and calculate the nitriding layer depth and hardness gradient online. The nitriding effect can be controlled in real time.
PJ- vacuum pulse nitriding furnace is a standard energy saving and environment friendly periodic operation nitriding furnace. It is mainly used for various heat treatment processes, such as nitriding, nitrocarburizing, pre-oxidation, post-oxidation, oxygen-nitriding and so on, for all kinds of steel mechanical parts, auto parts, die materials, stainless steel materials, nitriding, nitrocarburizing, pre-oxidation, post-oxidation, oxygen-nitriding and so on.
