Characteristics of heat treatment nitriding furnace
(1) the processing temperature is low, the time is short, and the deformation of workpiece is small.
(2) it is not limited by the steel type. Carbon steel, low alloy steel, die steel, stainless steel, cast iron and non metallurgical materials of iron-based powder can be treated by soft nitriding. The surface hardness of workpieces after soft nitriding is related to nitriding process and materials.
(3) nitriding furnace can significantly improve the fatigue strength, wear resistance and corrosion resistance of workpieces. Under the dry friction condition, it also has the properties of anti scratch and anti bite.
(4) as there is no brittle ξ phase in the soft nitriding layer, the nitriding layer has certain toughness and is not easy to peel off.
Therefore, at present, soft nitriding has been widely used in the processing of wear-resistant workpieces such as dies, measuring tools, cutting tools (such as high-speed steel cutting tools), crankshafts, gears, cylinder liners, mechanical structural parts, etc.
