摘要： A manufacturing method of case-hardened parts whose chemical components comprising especially Fe, C, Si, Mn, S, Ni, Mo, Al, V and N including a step of the heat treatment 1 in which, after carburizing, carbonitriding or carburizing followed by carbonitriding steel is cooled gradually at a temperature less than 100.degree. C./minute, by another step of the heat treatment 2, in which steel is heated to a temperature higher than the Ac.sub.3 transformation point and less than 850.degree. C. and kept at the above temperature before quenching, or after keeping at the temperature, is cooled down to a level not below 600.degree. C. before quenching, or quenching is done after cooling down to and keeping the temperature not below 600.degree. C. is disclosed. This method makes the surface layer a mixture of martensite and retained austenite. Thus the case hardened steel products of high precision and high strength are obtainable.

摘要： Provided is a resin-coated saw wire that, when used to cut a workpiece, has a shallow depth of a damaged layer and can give a cut article having a smooth surface. The resin-coated saw wire is used in cutting of the workpiece using a sawing machine and includes a steel wire and a resin coating covering the steel wire surface. The resin coating contains substantially no abrasive grain, has a hardness at 120° C. of 0.07 GPa or more, and has a hardness controlled so as to prevent abrasive grains from coming into the resin coating, which abrasive grains are sprayed during workpiece cutting.
