Abstract

aço martensítico resistente ao calor para aplicações de caldeira com uma combinação única de resistência à fluência acentuada e excelente resistência à oxidação na exposição em alta temperatura em ambientes contendo vapor, tendo a seguinte análise de substancia derretida (% em peso): c: 0,10 a 0,16%, si: 0,20 a 0,60%, mn: 0,30 a 0,80%, p = 0,020%, s = 0,010%, al = 0,020%, cr: 10,50 a 12,00%, mo: 0,10 a 0,60%, v: 0,15 a 0,30%, ni: 0,10 a 0,40%, b: 0,008 a 0,015%, n: 0,002 a 0,020%, co: 1,50 a 3,00%, w: 1,50 a 2,50%, nb: 0,02 a 0,07%, ti: 0,001 a 0,020%. o equilíbrio do aço consiste em ferro e impurezas inevitáveis. o aço é normalizado por um período de aproximadamente 10 a aproximadamente 120 minutos na faixa de temperatura entre 1050ºc e 1170ºc e resfriado em ar ou água para a temperatura ambiente e depois revenido por pelo menos uma hora na faixa de temperatura entre 750ºc e 820ºc. ele exibe microestrutura martensítica com conteúdo médio de ¿-ferrita menor do que 5 % em vol.heat resistant martensitic steel for boiler applications with a unique combination of enhanced creep resistance and excellent oxidation resistance on high temperature exposure in vapor-containing environments, having the following melt substance analysis (% by weight): c: 0, 10 to 0.16%, bs: 0.20 to 0.60%, mn: 0.30 to 0.80%, p = 0.020%, s = 0.010%, al = 0.020%, cr: 10.50 to 12.00%, mo: 0.10 to 0.60%, v: 0.15 to 0.30%, ni: 0.10 to 0.40%, b: 0.008 to 0.015%, n: 0.002 to 0.020 %, co: 1.50 to 3.00%, w: 1.50 to 2.50%, nb: 0.02 to 0.07%, ti: 0.001 to 0.020%. The balance of steel consists of iron and inevitable impurities. The steel is normalized for a period of approximately 10 to about 120 minutes in the temperature range between 1050 ° C and 1170 ° C and cooled in air or water to room temperature and then tempered for at least one hour in the temperature range between 750 ° C and 820 ° C. it exhibits martensitic microstructure with mean ferrite content of less than 5% by vol.
