Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the corrosion resistance of an alloy steel for cutting tool, prepared by sintering and densifying a steel powder by means of hot isostatic pressing, while maintaining its high hardness and high toughness. SOLUTION: This alloy steel for cutting tool is obtained by sintering and densifying a steel powder by means of hot isostatic pressing. At this time, this alloy steel has a composition consisting of, by weight, 0.9-1.5% C,
