摘要： Provided is a cold work tool material capable of reducing dimensional changes which occur, due to heat treatment, in the longitudinal direction of the material during quenching and tempering. This cold work tool material is drawn through hot working, has an annealed structure including carbides, and is used after being quenched and tempered, wherein, in the annealed structure which is formed in a cross section parallel to a drawing direction due to the hot working of the cold work tool material, the standard deviation in the degree of orientation of carbides Oc, as determined by equation (1) below, is 6.0 or more for carbides having a circle equivalent diameter of 5.0 μm or greater as observed in the annealed structure in the cross section at right angle to a direction perpendicular to the drawing direction. Oc=D×θ . . . (1), where D represents the circle equivalent diameter (μm) of the carbide, and θ represents the angle (rad) between the major axis of an approximate ellipse of the carbide and the drawing direction. A cold work tool using the cold work tool material and a method for manufacturing the same are also provided.

摘要： A tool steel family with outstanding thermal diffusivity, hardness and wear resistance has been developed, also exhibiting good hardenability. Also its mechanical strength, as well as its yield strength, at ambient and high temperature (superior to 600° C.) are high, due to a high alloying level in spite of the high thermal conductivity. Because of its high thermal conductivity and good toughness, steels of this invention have also good resistance to thermal fatigue and thermal shock. This steels are ideal for discontinuous processes where it is interesting to reduce cycle time and that require high hardness and/or wear resistance (plastic injection molding, other plastic forming processes and curing of thermosets, hot forming of sheet . . . ). These tool steels are also appropriate for processes requiring high wear resistance and good resistance to thermal fatigue (forging, hot stamping, light-alloy injection . . . ).
