Description

Gegenstände (Gefäße, Rohre, Maschinenteile, usw.), die hohe Widerstandsfähigkeit gegen Korrosion durch Chlorammoniumlösungen erfordern. Die Erfindung bezieht sich auf Gegenstände (Gefäße, Rohre, Maschinenteile usw.), die hohe Widerstandsfähigkeit gegen Korrosion durch Chlorammoniumlösungen erfordern, und besteht darin, daß zur Herstellung dieser Gegenstände eine Stahllegierung verwendet wird, die 18 bis 2.¢ Prozent Chrom, 7 bis 2o Prozent Nickel, 2 bis 6 -Prozent Kupfer und o,z bis 0,4 Prozent Kohlenstoff enthält.Objects (vessels, pipes, machine parts, etc.) that are highly resistant against corrosion by chlorammonium solutions. The invention relates to on objects (vessels, pipes, machine parts, etc.) that are highly resistant require against corrosion by chlorammonium solutions, and consists in that for To manufacture these items a steel alloy is used that is 18 to 2. ¢ Percent chromium, 7 to 20 percent nickel, 2 to 6 percent copper and o, z to 0.4 Contains percent carbon.

Es sind bereits Chroinnickelstahllegierungen bekannt, die zur Herstellung von Gegenständen geeignet sind, die hohe Widerstandsfähigkeit gegen Korrosion erfordern. Stahllegierungen dieser Art erlangen jedoch erst durch den Zusatz von Kupfer eine besonders hohe Widerstandsfähigkeit gegen den Angriff von Chlorammoniumlösungen. Diese Lösungen werden z. B. bei der Erzeugung von Düngesalmiak in großen Mengen eingedampft, und die Erfahrung hat gezeigt, daß die bekannten Chromnickelstahliegierungen gegen diese salmiakhaltigen Lösungen nicht genügend widerstandsfähig sind. Durch die Verwendung kupferhaltigerChrbmnickelstahllegierungen wird jedoch der Fortschritt erreicht, daß man widerstandsfähige Gefäße zum Eindampfen der Chlorammoniumlösungen herstellen kann.There are already chromium nickel steel alloys known for the production of objects that require high resistance to corrosion. However, steel alloys of this type only achieve a through the addition of copper particularly high resistance to attack by chlorammonium solutions. These solutions are z. B. in the production of fertilizer almiac in large quantities evaporated, and experience has shown that the well-known chromium-nickel steel alloys are not sufficiently resistant to these solutions containing ammonia. By however, the use of copper-containing chrome-nickel steel alloys is advancing achieves that one resistant vessels for the evaporation of the chlorammonium solutions can produce.
