Abstract
"AçO INOXIDáVEL FERRìTICO TENDO RESISTêNCIA à FLUêNCIA EM ALTAS TEMPERATURAS". Um aço inoxidável ferrítico, tendo propriedades mecânicas em altas temperaturas, inclui mais de 25 por cento em peso de cromo, 0,75 até 1,5 por cento em peso de molibdênio, até 0, 05 por cento em peso de carbono e pelo menos um de nióbio, titânio e tântalo, em que a soma das percentuais em peso de nióbio, titânio e tântalo satisfaz a equação 0,4 < (%Nb + %Ti +1/2 (%Ta)) <243> 1. O coeficiente de expansão térmica do aço inoxidável ferrítico está dentro de cerca de 25% do CTE da zircónia estabilizada entre 20<198>C (68<198>F) e 1.000<198>C (1.832<198>F), e o aço apresenta pelo menos uma propriedade de fluência selecionada da tensão geradora de ruptura por fluência de pelo menos 6.895 kPa (1.000 psi) a 900<198>C (1.652<198>F), tempo para deformação por fluência de 1% de pelo menos 100 horas a 900<198>C (1.652<198>F) , sob carga de 6.895 kPa (1.000 psi), e tempo para deformação por fluência de 2% de pelo menos 200 horas a 900<198>C (1.652<198>F), sob carga de 6.895 kPa (1.000 psi). O aço é particularmente adequado para aplicações em altas temperaturas, incluindo, mas não limitado a, interconexões de coleta de corrente em células de combustível de óxidos sólidos, ferragens de fornos, equipamento para processo químico, petroquímica, geração de energia elétrica e indústrias de controle de poluição, e equipamento para manuseio de cobre em fusão e outros metais em fusão.
