Abstract

268,716. Krupp Akt.-Ges., F. April 3, 1926. [Convention date]. Grant of Patent refused. Purifying.-Iron and steel are deoxidized to an oxygen content of less than 0.005 per cent which is determined as part of the manufacture by the fact that the aged state does not cause any substantial decrease in the tenacity of the notched bar under test. In making this iron or steel, a quantity of molten metal is heated in a smelting-oven, and a quantity of aluminium or other agents, e.g. titanium, zirconium, vanadium, magnesium, or silicon, is introduced. The metal is de-oxidized and run off. After solidification, a trial rod is cut off, and is submitted to artificial decay A sample is cut off from this. and is submitted to a cutting-test. The quantity of aluminium &c. is varied until the result of the test is satisfactory. The process may be carried out by means of carbon in a vacuum.
