Abstract

Patente de Invenção: "MéTODO DE PRODUçãO DE PLACAS COM GRAU DE RESISTêNCIA àS INTEMPéRIES E PRODUTO A PARTIR DE TAL PLACA". Um método de produção de uma placa de aço do grau resistente às intempéries que inclui as etapas de moldagem, laminação a quente, e resfriamento acelerado usando-se uma composição modificada de liga do grau resistente às intempéries. A composição emprega níveis eficazes de manganês, carbono, nióbio, molibdênio, nitrogênio e titânio. Após a moldagem, a placa ou lingote é aquecida e sofre laminação bruta até uma placa mensurável intermediária. A placa mensurável intermediária é laminada com uma temperatura final controlada e submetida ao resfriamento acelerado. Com a química da liga, a laminação e o resfriamento controlados, a placa com a espessura final mostra uma elasticidade contínua e pode ser usada para aplicações que necessitem uma resistência à deformação mínima de 70 KSI, uma resistência à tração de 90-110 KSI, e uma tenacidade Charpy medida com entalhe em V maior que 23,68 m/kg (35 ft-Ibs) a -23,33<198>C (-10<198>F) em placas de até 10,16 cm (4,0 polegadas) de espessura.
