Abstract

resumo patente de invenção: "aço de baixa liga". a presente invenção refere-se a um aço de baixa liga submetido a um tratamento térmico pós-soldagem, contendo, em % em massa, c: 0,01 a 0,15%, si: 3% ou menos, mn: 3% ou menos, e al: 0,08% ou menos, um ou mais tipos de elementos selecionados entre ti, v e nb: a faixa satisfazendo a fórmula (1), e o saldo sendo fe e impurezas, em que nas impurezas, n: 0,01% ou menos, p: 0,05% ou menos, s: 0,03% ou menos, e o: 0,03% ou menos: 0,1 ´ [c(%)] £ [ti(%)] + [v(%)] + 0,5 ´ [nb(%)] £ 0,2 ... (1) em que o símbolo do elemento na fórmula representa o teor (% em massa) de cada elemento. no aço de liga, a haz submetida ao pwht, especialmente pwht de curto tempo, tem excelente resistência à fragilização pelo hidrogênio em ambientes úmidos de sulfeto de hidrogênio ou similares.Patent Summary: "Low Alloy Steel". The present invention relates to a low alloy steel subjected to a post weld heat treatment, containing by weight% c: 0.01 to 0.15%, si: 3% or less, mn: 3% or less, and al: 0.08% or less, one or more element types selected from ti, v nb: the range satisfying formula (1), and the balance being fe and impurities, where in impurities, n: 0.01% or less, p: 0.05% or less, s: 0.03% or less, and o: 0.03% or less: 0.1 ´ [c (%)] £ [ti (% )] + [v (%)] + 0,5 ´ [nb (%)] £ 0,2 ... (1) where the symbol of the element in the formula represents the content (% by mass) of each element. In alloy steel, pwht haz, especially short-time pwht, has excellent resistance to hydrogen embrittlement in humid hydrogen sulfide or similar environments.
