The invention relates to a process and apparatus for press-forming and quenching a steel stock such as diaphragm spring for automotive clutch use. In the invention, the stock is preparatorily heated to its austenitizing temperature such as about 800 DEG C., or so, placed on one of two cooperating die elements, and then squeezed therebetween under pressure, said die elements having working surfaces having corresponding dimensions and configurations so as to be brought into a pressurized and heat-conducting contact with the to-be-quenched zone of said stock, thereby said stock being press-formed to its desired shape and wholly or locally quenched to a desired hardness such as HRC 60 DEG by conducting substantial amount of heat from the stock to the die elements.
