The company is mainly engaged in: vacuum heat treatment, vacuum carburizing treatment, ion nitriding, metallographic inspection, metal material failure analysis, heat treatment technical consultation and so on.
Low temperature carburizing of stainless steel
Stainless steel Low Temperature carburizing (Low Temperature Carburrizing) technology is a kind of can improve the stainless steel surface hardness and can keep the stainless steel rust resistance of a reinforcement technology, stainless steel and ordinary ion nitriding process relatively high Temperature, the permeability layer hardness is higher, usually larger than HV900, however, carbonitriding layer of anti-rust performance fell sharply, do salt fog test in the last few hours will rust spots.
The low temperature carburizing process of stainless steel can be obtained on the surface of stainless steel a layer of hardness that is high and rust resistance performance of a hardened layer, the surface hardness is about HV800, the thickness of the layer about 20-30um.
Ionic nitrogen carburizing
Plasma Nitro-Carburiizing process can infiltrate nitrogen and carbon elements into the surface of parts at the same time, which is characterized by thicker white light layer (compound layer), especially for some low carbon alloy steel, structural steel, etc., with good hardening effect. For example, 10-20um white light layer can be obtained on the surface of Q235 after ion nitrogen Carburiizing.
Low temperature ion nitriding
Low temperature ion nitriding (nitriding) is one of the unique advantages of ion nitriding (nitriding), the nitriding (nitriding) temperature range is 400-540C. At present, gas and liquid nitriding (nitriding) technology cannot achieve such a low nitriding temperature. Low temperature ion nitriding (nitriding) technology is mainly used in high alloy die steel, relatively low temperature can control the nitriding layer composition, do not form a crisp white layer (compound layer). The service life of the die can be improved in some specific working conditions. The company's current low-temperature ion nitrification (nitrification) products are SKD-11 and H13 molds. After testing, the nitrification layer can be controlled within 2-20um according to different customer needs. Surface hardness is HV0.5=1100-1200.
Ionic nitrogen carburizing
Oxidation after ionic nitrogen carburizing refers to the parts after the ionic nitrogen carburizing, in the thick white light layer (compound layer) on the basis of oxidation treatment, make the surface get a layer of dense oxide layer, further improve corrosion resistance. Its application objects are mainly alloy steel with relatively low carbon content and structural steel with less alloying element content, such as Q235.
