ABSTRACT:
A composite steel material consisting of two metallically joined steel components having different chemical compositions is disclosed. The first component is a high-speed tool steel or other high alloy tool steel having a carbon activity and a hardness and wear resistance in the same order as that of high speed tool steel. The second component is a steel consisting essentially of 0.40-0.45 weight percent carbon, 0.40-1.00 weight percent silicon, 0.40-1.00 weight percent manganese, 2.5-4.0 weight percent chromium, 0.50-1.50 weight percent molybdenum, 0.20-0.45 weight percent vanadium, balance iron and normal impurities.
