Abstract
Iron alloys capable of precipitation hardening, and suitable for cutting and hot-working tools, contain 10-35 per cent of tungsten or 2-12 per cent of molybdenum or both, 25-50 per cent of cobalt, 0,1-1 per cent of carbon, 3-15 per cent of chromium and up to a total of 10 per cent of one or more of the metals vanadium, titanium, and tantalum. If there is only one of these three metals there is at least 6 times as much vanadium as carbon, or at least 4 times as much titanium as carbon, or at least 6,5 times as much tantalum as carbon; if there is more than one, there is a corresponding total amount in relation to the carbon content. The alloys are heat treated by being cooled quickly from about 800-1000 DEG C., followed by reheating. Specification 408,866 is referred to.
