Abstract

This invention provides a stainless steel sheet that does not require quenching after stamping and is suitable as a material for disc brakes on various two-wheeled vehicles. This invention achieves this by appropriately controlling the composition, setting the area fraction of tempered iron to 70.0~100.0%, and setting the effective carbide precipitation amount E, as defined by the following formula (1), to 2.0% by mass or less. E=2×Fe2C+Cr23C6･･･(1) Here, Fe2C: the precipitation amount of Fe2C (mass%) and Cr23C6: the precipitation amount of Cr23C6 (mass%).
