Abstract: The invention provides a method of manufacturing a ferrous monolithic component and the component that results from the method. The method of the invention utilizes selective rapid cooling of the portion of the component that is desired to have increased strength and selective controlled cooling of the portion or portions which are desired to be more machinable. The controlled cooling may include cooling, re-heating and re-cooling. The result is a component with local high strength in the rapidly cooled zones and locally altered metallurgical properties to improve machinability in the more slowly cooled zones.
