Abstract

"TIRAS DE AçO INOXIDáVEL AUSTENìTICO COM UMA SUPERFìCIE DE APARêNCIA FOSCA. A presente invenção refere-se a um processo para a produção contínua de uma tira de aço inoxidável austenítico tendo uma superfície de aparência fosca, consistindo na sujeição de uma tira de aço inoxidável austenítico a um tratamento térmico em um forno de recozimento brilhante dentro do qual circula um gás de descarga inerte ou redutor, o qual tem um ponto de orvalho acima de -15 C, e então em decapar a tira usando-se uma solução de decapagem ácida adequada.
