Abstract
PURPOSE: A tool steel which is endowed with excellent cracking resistance, excellent softening resistance, excellent high-temperature strength, and longer longevity by nitriding treatment and which contains C, Si, Mn, Cr, W, Mo, V, and Fe and specific amounts of usual impurities.
CONSTITUTION: The tool steel contains 0.30 to 0.45% C, ≤1.20% Si, ≤1.20% Mn, 4.00 to 4.80% Cr, 1.50 to 3.50%(0.5W + Mo), 0.60 to 1.50% V, and Fe and usual impurities, together with any one or both of ≤2.00% Ni and 0.40 to 6.00% Co as needed. The tool steel, which is endowed with excellent cracking resistance, excellent high-temperature strength, excellent softening resistance for core portion, as well as longer longevity, by nitriding treatment, is suitable for mold, e.g., Al hot extrusion die, etc., which is liable to stress concentration shapely.
