JIS SUS420J1 / AISI 420 Stainless Steel Sheets / Plates For Brake Disc Motorcycle
Martensitic stainless steel JIS SUS420J1 for motorcycle brake disks.
SUS420J1 (13%Cr-0.2%C) and SUS420J2 (13%Cr-0.3%C) had mainly been used as rotor materials.
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.
Characteristics
good heat resistance and corrosion resistance
