Steel for metal-cutting tools

a metal-cutting tool and steel technology, applied in the field of steel for metal-cutting tools, can solve the problems of high content of expensive alloying elements, high alloying costs and therefore high material costs, high heat-treatability quality, etc., and achieve high hot hardness and toughness, low cutting wear on the tool, and special cost-effectiveness

Abstract

A steel for metal-cutting tools comprising carbon, chromium, molybdenum, vanadium, aluminum and nitrogen in certain concentration ranges. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application claims priority under 35 U.S.C. Β§119 of Austrian Patent Application No. A 965 / 2003, filed on Jun. 23, 2003, the disclosure of which is expressly incorporated by reference herein in its entirety. BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a steel for metal-cutting tools. 2. Discussion of Background Information Cutting areas of tools are essentially highly stressed thermally, abrasively and in terms of toughness and compressive stress during a metal cutting of workpieces, and the stressing of the workpiece material takes place simultaneously. Alloy compositions which that take into account the highest demands in the stress profile to achieve the longest service life of the tool are known. High wear resistance of a tool can be achieved in general with the use of high-speed steels, but these have high contents of the expensive alloying element(s) molybdenum and / or tungsten in concen...
