UNITED STATES PATENT OFFICE.
BENNO STRAUSS, O'F ESSEN-BREDENEY, GERMANY, ASSIGNOR TO FRIED. KRUPP AKTIENGESELLSGHAFT, OF ESSEN-ON-THE-RUHR, GERMANY.
STEEL ALLOY.
No Drawing.
To all whom it may concern:
Be it known that I, Bmmo STRAUSS, residing at 289 Alfredstrasse, Essen-Bredeney, Germany, a citizen of the German Republic,
6 have invented a certain new and useful Improvement in Steel Alloys, of which the following is a specification.
This invention relates to a composition of matter to be used for manufacturing articles 10 (vessels, pipes, machinery parts, etc.) which require a high resistibility against corrosion by ammonium-chloride solutions.
The composition consists of a steel alloy containing 18 to 24 per cent of chromium,
15 7 to 20 per cent of nickel, 2 to .6 per cent of copper and 0.1 to 0.4 per cent of carbon.
I am aware that chromium-nickel-steel alloys are already well-known which are adapted to be used for manufacturing articles requiring a high resistibility against corrosion. However, it is only by the addi-. tion of copper that steel alloys of the said Application filed July 17, 1923. Serial No. ssaias.
kind will obtain a particularly high resistibility against the attacks of ammoniumchloride solutions.
These solutions are in the ammoniumillaim.
chloride solutions.
As a composition of matter for use in manufacturing articles reqlurlng a high resistiblhty against corrosion by ammoniumchloride solutions, 18 to 24 per cent 0 a steel alloy containing 1 CllI'Ol'llllllll, T to 20 per cent of nickel, 2 to 6 per cent of copper and .1 to 0.4 per cent 0 1: carbon.
BENNO STRAUSS.
