FERRITE STAINLESS STEEL SHEET FOR BELLOWS STOCK PIPE

摘要

A ferrite stainless steel sheet for bellows stock pipe that excels in workability. In particular, there is provided a ferrite stainless steel sheet for bellows stock pipe characterized by containing 10 to 25 mass% of Cr, having a yield stress of 300 to 450 MPa and exhibiting a product of yield stress multiplied by uniform elongation of 5200 MPa·% or greater. In preferred form, there is provided a ferrite stainless steel sheet for bellows stock pipe whose average crystal grain diameter (D) is 35 µm or less, or whose surface roughness in terms of Ra is 0.40 µm or less.
