  • Method for producing a rotatable gray iron brake component
    Patent number: 5603784
    Abstract: A method for producing a brake component involves providing a cast gray iron rotatable brake component where the gray iron has a carbon content between 3.4% and 4.0%. The brake component is subjected to an austempering heat treatment process. Then it is subjected to a re-tempering process to provide a microstructure which consists of spheroidized pearlite carbon in a matrix of bainitic and austenitic ferrite.
