Through hardened screw use imported high speed steel, after series of quenching & annealing process to achieve high toughness & hardness, especially suitable for high wearing production.Nitriding is a case hardening process for steel material. Gas nitriding is a surface hardening process, where nitrogen is added to the surface of steel parts using dissociated ammonia as the source. Gas nitriding develops a very hard case in a component at relatively low temperature, without the need for quenching. Nitriding is carried out at temperatures below the transformation temperature of alloy steels, so that with proper manufacturing techniques, there is little or no distortion as a result of the process. Parts to be nitrided are heat treated to the proper strength level, and final machined. The parts are then exposed to active nitrogen at a carefully controlled temperature, typically in the range of 500 c to 530 c. As a result, a very high strength product with extremely good wear resistance can be produced, with little or no dimensional change. The components to be nitrided are often stress relieved prior to final machining so that the only size changes observed are growth of about .01 mm. In some cases, nitrided components are surface ground after nitriding to remove the most outermost brittle layer produced by the process, or to bring parts into a tight tolerance.
