procédé pour rendre l'acier tnsenstble à l'action de gaz et --J vapeurs chauffés.
Des essais approfondis ont permis de constater qu'il est techniquement très avantageux d'utilisera pour la fabri- cation d'objets exigeant une grande résistance à l'action de gaz, vapeurs et liquides chauffés, des alliages d'acier, renfermant environ 0.05-0.2 %-de carbone, environ 5-12% de chrome, et environ 0.2-1% de molybdène, éventuellement avec environ 0.2-0.5% de vanadium, et traités d'après le procédé décrit dans le brevet principal N 338313 du 22 Décembre 1926.
Les objets fabriqués en ces alliages d'acier et amélio- rés de la manière indiquée se caractérisent notamment par les
<Desc/Clms Page number 2>
avantages sutvants très importants au point de vue tech- nique,. Ils présentent une texture, qui est exempte de limites de grains; ils possèdent - probablement à cause du manque de limites de grains - une résistance très forte contre l'attaque d'hydrogène, se produisant sous de fortes pressions et à des températures élevées; 'ils présentent enfin en particulier lors'de la présence simultanée de molybdène et de vanadium - une résistance à chaud très élevée. @

process for making steel resistant to the action of heated gases and vapors.
Extensive tests have shown that it is technically very advantageous to use for the manufacture of objects requiring a high resistance to the action of gases, vapors and heated liquids, steel alloys, containing approximately 0.05 -0.2% -of carbon, about 5-12% of chromium, and about 0.2-1% of molybdenum, optionally with about 0.2-0.5% of vanadium, and treated according to the process described in main patent N 338313 of 22 December 1926.
Articles made of these steel alloys and improved in the manner indicated are characterized in particular by the
<Desc / Clms Page number 2>
very important advantages from the technical point of view. They exhibit a texture, which is free from grain boundaries; they possess - probably because of the lack of grain boundaries - a very strong resistance against hydrogen attack, occurring under high pressures and high temperatures; Finally, in particular when molybdenum and vanadium are present at the same time, they exhibit a very high resistance to heat. @
