摘要

PCT No. PCT/JP82/00210 Sec. 371 Date Dec. 3, 1982 Sec. 102(e) Date Dec. 3, 1982 PCT Filed May 28, 1982 PCT Pub. No. WO82/04268 PCT Pub. Date Dec. 9, 1982.This invention belongs to the technical field of martensitic stainless steels and the moderate hardness, toughness and corrosion resistance required for motorcycle braking disc materials can be provided only by quenching at a broad range of quenching temperature by restraining the content of C+N in the steels to 0.04-0.10% and containing 1.0-2.5% of Mn and 10.0-14.5% of Cr.
