    • PROBLEM TO BE SOLVED: To provide a process for producing a grain-refined martensitic stainless steel which has high strength and high corrosion resistance and is suitably used for manufacturing electric razors, hair clippers, etc., requiring sharp cutting edges, and a cutting tool using this stainless steel. SOLUTION: A base material based on a composition of SUS420J2 is prepared, subjected to at least one process chosen from a high-density dislocation generation process and rapid solidification process, and further annealed to obtain a ferrite steel with fine metallic structure. Next, the ferrite steel is cold rolled, annealed, subjected to plastic working to yield a cutting tool of a predetermined shape, and further quenched to obtain the grain-refined martensitic stainless steel. By sharpening it through grinding/polishing, the cutting tool made of the grain-refined martensitic stainless steel can be obtained. COPYRIGHT: (C)2004,JPO
    • 要解决的问题:提供一种具有高强度和高耐腐蚀性的精制马氏体不锈钢的制造方法,适用于制造需要锋利的切削刃的电动剃须刀,剪发机等,以及 使用这种不锈钢的切削工具。 解决方案:制备基于SUS420J2的组成的基材,经受从高密度位错产生工艺和快速凝固过程中选择的至少一种工艺,并进一步退火以获得具有金属细结构的铁素体钢。 接着,对铁素体钢进行冷轧,退火,进行塑性加工,得到规定形状的切削工具,进一步淬火,得到精制马氏体系不锈钢。 通过磨削/研磨进行磨削,可以得到由精制马氏体系不锈钢制成的切削工具。 版权所有(C)2004,JPO
