Abstract
"PROCESSO DE TRATAR UM AçO INOXIDáVEL". Aço inoxidável resistente ao calor pode ser tratado em uma baixa atmosfera de oxidação em uma seq³ência de aquecimento/impregnação - aquecimento/impregnação para esgotar sua superfície de Ni e Cr que tende a catalisar a coqueificação de hidrocarbonetos em contato com a superfície do aço inoxidável, e enriquecê-lo com elementos que são inertes para a formação de coque. As partes feitas de aço inoxidável, tal como bobinas ou tubos de fornalha, tratados de acordo com a presente invenção quando usados tem uma taxa significantemente reduzida de coqueificação catalítica.
