摘要
The invention relates to a process for producing a thin cast piece of Cr-Ni stainless steel sheet of nearly the same thickness as that of final products by a synchronous continuous casting process which comprises conducting quenching of the thin cast piece just after casting in a high-temperature region, hot or cold processing of said piece, annealing, etc. to thereby reduce the size of gamma grains and cooling in a lower temperature region at 900°C or below to thereby prevent precipitation of chromium carbide in a grain boundary. This process enables roping or uneven luster on the surface of stainless steel sheet to be depressed.
