摘要：A method for the manufacture of components made of steel subject to heavystress, load and/or wear, such as rolling bearing elements, starting from a steel having anaustenite carbon content at hot forming temperature of about 800 - 1100°C of 0.55-0.85wt%,hot forming of the components above Al of the steel,hardening of the componentsdirectly from the hot forming temperature, in air, possibly forced convection aided byaddition of water,hard machining of the components to their final dimensions,surfacefinishing of the components.
