ABSTRACT:
A low anisotropic Cr--Ni-based stainless steel hot-rolled sheet, which has texture with (100), (110), (111), (311) and (211) ND plane intensity from 0.5 to 1.5 in an inverse pole figure measured for a 1/4 section of the sheet thickness, and which is produced by continuously casting molten Cr--Ni-based stainless steel into a cast strip with a thickness of 1.5 mm to 6 mm using a continuous casting machine wherein the mold walls move in synchronization with the cast strip, hot rolling it at a hot rolling temperature of 950-1,150.degree. C. and a reduction of 25 to 35% within 60 seconds after the cast strip has left the mold, and then performing heat treatment wherein the strip is held for 5 to 60 seconds in a temperature range of 950-1,200.degree. C.; as well as a process for its production.
