发明名称 Sätt att tillverka komponenter av stål
摘要 A method for the manufacture of components made of steel subject to heavy stress, load and/or wear, such as rolling bearing elements, starting from a steel having an austenite carbon content at hot forming temperature of about 800 - 1100 DEG C of 0.55-0.85 wt%, hot forming of the components above Al of the steel, hardening of the components directly from the hot forming temperature, in air, possibly forced convection aided by addition of water, hard machining of the components to their final dimensions, surface finishing of the components. <IMAGE>
