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.
