Abstract

A process for the continuous casting of an austenitic stainless steel strip directly from liquid metal of composition, expressed in percentages by weight: C≰0.08%, Si≰1%, Mn≰2%, P≰0.045%, S≰0.03%, Cr between 17.0 and 20.0%, Ni between 8.0 and 10.5% on a machine for casting onto one or between two moving walls whose external surface is provided with dimples and in which the region surrounding the meniscus is inserted with an inerting gas of controlled composition, characterized in that : a Cr (equ) / Ni (equ) ratio greater than 1.55 is conferred on the liquid metal, with: Cr (equ)=%Cr+1.37 X %Mo+1.5 X%Si=2%Nb+3%Ti and Ni (equ)=%Ni+0.31%Mn+22%C+14.2%N+%Cu; one or more moving walls are used whose entire surface includes touching dimples having a diameter of between 100 and 1500μm and a depth of between 20 and 150μm: and an inerting gas is used consisting, at least partially, of a gas which is soluble in steel.
