Abstract
A brake disk and process for producing the same which is particularly suitable for use on motorcycles. A stainless steel material of particular chromium content is subjected to a heat-treating and press-quenching step to form a brake disk having a sufficient hardness required for the function of a brake and being of favorable appearance for use on motorcycles.
Claims8
A process for producing a brake disk characterized in that it is fabricated substantially of a martensitic stainless steel plate material containing at least 10% chromium and having a suitable surface hardness for a brake, including the step of:
- integrally combining an annular disk member shaped by press-quenching said material to be of a hardness required for the function of a brake with a separate hub fitting member.
A process for producing brake disks characterized by heating a martensitic stainless steel plate material containing at least 10% chromium to be at an imperfectly quenching temperature set at a hardness required for a brake disk and press-quenching said heated steel plate material to obtain a brake disk of a predetermined shape.
