    摘要: An austenitic stainless steel sheet is produced by a twin-roll synchronous continuous casting process wherein the sheet has a Ni segregation ratio in the vicinity of its center section of 0.90 or more and .delta.Fe.sub.cal. (mass %) is 6 mass % or more. Ni segregation ratio is defined by the formula: {average Ni content of the segregated portion (%) }/{average Ni content of the cast sheet (%)}; where Ni content is expressed in % by mass. .delta.-Fe.sub.cal. (mass %) is defined by the formula: 3(Cr+1.5 Si+Mo+0.5 Nb)-2.8(Ni+0.5 Cu+0.5 Mn+30 C+30 N)-19.8; wherein the chemical elements are given in % by mass.
