Martensitic Stainless Steel JIS SUS410 SUS420J1 Plate For
Motorcycle Brake Disks
Disk brake systems are widely used for motorcycles because they are
effective in radiating heat and stabilizing
the brake performance. The disk brake is a system which slows down
a motorcycle by frictional force generated
when brake pads clamp a rotor rotating in linkage with a wheel from
both sides.
The rotor needs proper hardness (generally, Rockwell hardness of
32–38HRC) to secure
wear resistance and deformation resistance, and also needs
sufficient heat resistance to
maintain these properties under the heat generated by braking.
Corrosion resistance is also required to maintain brake performance
and for the reason of appearance.
Therefore, martensitic stainless steel, which provides both heat
resistance and corrosion resistance,
is used as a material for rotors.
Conventionally, JIS SUS410, SUS420J1 (13%Cr-0.2%C) and SUS420J2
(13%Cr-0.3%C) had mainly been used as rotor materials.
