摘要： The object of the present invention is to provide a method for the manufacturing of a cutting material possessing excellent toughness and a high strength. The composition by weight of the Nickel alloy ingot, is chromium (Cr )14-23%, molybdenum (Mo) 14-20%, tungsten (W) 0.2-5%, iron (Fe) 0.2-7%, cobalt (Co) 0.2-2.5% with the remaining portion being made up of Ni and unavoidable impurities. After undergoing a solution heat treatment process, the Ni ingot undergoes plastic working, at a product ratio above 80%, followed by heating at a temperature of 500.degree.-600.degree. C. for longer than 30 minutes. Heating the alloy of the aforementioned composition at the above mentioned temperature promotes the precipitation of an intermetallic compound possessing a hardness greater than 57 on the HRC. The resulting superior cutting material is resistant to corrosion even when exposed to sea water. The cutting material obtained through the process of the present invention provides a high resistance to both rust and chipping in addition to a high abrasion resistance, all of which are advantages over the conventional stainless steel cutting material.

摘要： A cutting apparatus comprises an endless chain body comprising a plurality of plate-like flaps connected to each other for angular movement in a common plane. Each flap has an end face on an inner peripheral side of the chain body, and at least a part of the flaps having a cutting device at the end face. The apparatus further comprises a plurality of sprockets supporting the chain body in tension, and defining a common plane of cut effected by the combination of the chain body and the sprockets. The chain body is supported by a rigid backplate, of thickness not greater than the thickness of the flaps. It provides a firm support to the rotating chain body to permit sliding movement of the chain body within the common plane of cut. The apparatus further comprises a means for activating the rotational movement of the sprockets in cooperation with the chain body, and a means for moving an object or the chain body toward each other to effect removal of a material disposed within the extended plane of the common plane of cut to effect separation of an object into severed sections.
