Patent ID: 7341637

Claim:
A ferritic stainless steel sheet excellent in press formability and operability, characterized by: containing, in mass, C: 0.001 to 0.01%, N: 0.001 to 0.015%, Cr: 10 to 19%, Si: 0.01 to 0.8%, Mn: 0.01 to 0.5%, P: 0.01 to 0.02%, S: less than 0.01%, Al: 0.005 to 0.1%, Ti: 0.05 to 0.25%, and V: 0.03 to 0.12%, with the balance consisting of Fe and unavoidable impurities; having a solid lubricating film or films on one or both of the surfaces; and having a ratio Z, defined as Z=Z 1 /Z 2 , of less than 0.5, a tensile strength of 450 MPa or less and an average r-value of 1.7 or more, wherein Z 1 is a friction coefficient of the surface of a solid lubricating film and Z 2 that of the surface of a reference material having a surface roughness Ra in the range from 0.05 to 0.07 μm and being coated with neither a coating nor lubricating oil.
