Abstract

Изобретение относится к дуплексной ферритно-аустенитной нержавеющей стали, обладающей высокой деформируемостью, связанной с TRIP-эффектом, и высокой стойкостью к коррозии со сбалансированным эквивалентом стойкости к точечной коррозии. Дуплексная нержавеющая сталь содержит менее 0,04 мас.% углерода, менее 0,7 мас.% кремния, менее 2,5 мас.% марганца, 18,5-22,5 мас.% хрома, 0,8-4,5 мас.% никеля, 0,6-1,4 мас.% молибдена, менее 1 мас.% меди, 0,10-0,24 мас.% азота, остальное представляет собой железо и неизбежные примеси, встречающиеся в нержавеющих сталях.
