Abstract
Alloy steels containing a precipitation hardening element, e.g. Cu Ti B Zr during cooling from a high temperature, e.g. the working temperature, are maintained at a predetermined temperature (200-800 DEG C.) to increase the hardness and strength by precipitation hardening. The cooling apparatus may be as described in Specification 358,785. In the case of copper alloy, the alloy is allowed to cool from its production temperature to 500 DEG C. and then maintained at 500 DEG C. for a few hours. The parts may be fed in on a conveyer to the cooling bed with insulated bottom and heat protecting hood. The sections may be covered with sand &c. as desired. After hardening rapid cooling by air, steam, or water may be used and gas burners and fresh air inlets for heating or cooling any part locally is provided, e.g. a steel containing 0,17 per cent C, 0,38 per cent Si, 1,2 per cent Mn, and 0,75 per cent Cu was slowly cooled from the rolling temperature down to 450 DEG and kept there for 20 hours and was then quickly cooled to hand temperature.
