Abstract
In the production of an alloy steel by adding tantalum, niobium, vanadium, zirconium, boron, or titanium to a high carbon iron containing at least 2 per cent of carbon whereby a suspension of the carbide of the added element is formed by reaction thereof with the carbon in the iron, the carbide so produced are isolated by chemical means such as treatment with hydrochloric acid, for use as abrasives, or for the manufacture of tools. The high carbon iron may comprise white pig iron with the addition, if necessary, of solid carbon.ALSO:An alloy steel particularly suitable for cutting tools, is produced by adding tantalum, niobium, vanadium, zirconium, boron, or titanium to a high carbon iron containing at least 2 per cent of carbon whereby a suspension of the carbide of the added element is formed by the reaction thereof with the carbon in the iron. The high carbon iron may consist of white pig iron with the addition, if necessary, of solid carbon. The amount of tantalum &c. which is added is sufficient to absorb all the carbons present in excess of 0,7 per cent, e.g. up to 40 per cent, so as to enable the matrix to be hardened by heat treatment, and known steel making elements such as chromium up to 30 per cent, tungsten up to 20 per cent, and molybdenum up to 10 per cent may be added to the matrix so produced. For the production of a steel which is capable of nitrogenization, tantalum, or niobium is added in excess of that required to absorb the carbon in the melt, together with aluminium. The carbide may be isolated by chemical means such as treatment with hydrochloric acid for use as an abrasive or for the manufacture of tools.
