Abstract

A presente invenção trata de uma composição e método de manufatura de produtos de aço inoxidável martensítico endurecível por precipitação, a composição compreendendo pelo menos 0,5% em peso de Cr e pelo menos 0,5% em peso de Mo, onde a soma de Cr, Ni e Fe excede 50%. As etapas do método incluindo fusão do material em uma extrusão a quente moldante, seguida de um número de etapas de deformação a frio, de maneira a obter-se pelo menos 50% de martensita, e finalmente envelhecimento a 425-525 <198>C para obter-se precipitação de partículas quasicristalinas. Tal material podendo ser utilizado em componentes de veículo onde exigências de resistência à corrosão, alta resistência e dureza devem ser satisfeitas.
