Abstract

Acier à 9% de chrome résistant à la chaleur ayant une excellente ténacité, de meme qu'une haute résistance au fluage dans un assemblage soudé. Cet acierdont les propriétés mécanique sont excellentes entre 500 et 550 degrés C convient éminemment pour la construction du surchauffeur dans une centrale électrique équipée d'un réacteur surgénérateur qui peut ainsi etre exploitée sans risque d'accident à une température maximale de surchaffeur.
