Abstract

Un particolare bilanciamento della composizione chimica assieme alla scelta di un trattamento termico di ricottura e tempra in condizioni controllate, consente di ottenere manufatti di acciaio super-duplex con eccellenti caratteristiche di resistenza alla corrosione e con tensione unitaria dì snervamento superiore a 90 ksi a temperatura ambiente, allo stato di lavorato a caldo.
