UNITED STATES. PATENT OFFICE.
JOSEPH MICHAEL FLANNERY, F PITTSBURGH, PENNSYLVANIA, ASSIGNOB TO STANDARD CHEMICAL COMPANY, OF PITTSBURGH, PENNSYLVANIA.
HIGH-SPEED STEEL.
.To all whom it may concern Be it known that I, J osnrn M. FLANNERY,
a citizen of the United States, and a resident of. Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvepointed out in the claims.
ments in High-Speed Steel; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in steel alloys, and more particularly to high speed molybdenum steel,one object of the invention being to produce a high speed steel which shall have added to the qualities of molybdenum thereof, similar qualities derived from the addition of another alloying metal which shall; serve to materially reduce the quantity of 'molybdenum used and at the same time increase the quality of the product in strength, ductility and heat-resisting properties, and enhance its efliciency for use as high speed tool steel.
A further object is to produce a high speed molybdenum steel having another metal alloyed therewith which will give superior cutting efiiciency tothe steel and at the same time permit of a reduction in the amount of molybdenum employed.
With these and other objects in view, the
invention consists in a certain novelhigh speed steel alloy as hereinafter set forth and The invention further conslsts in molybdenllllm steel having uranium alloyed therewit a In the manufacture of my improved high speed steel, I .alloy with molybdenum steel, uranium in a proportion appreciably less than that of molybdenum.
It is now commonpractice' in the manu-' Specification of Letters Patent.
Patented Jan. 2,1917.
Application and September 7,1916. Serial No. 118,877.
of uranium from .40 per cent. and not ex-.
ceeding three per cent. into molybdenum steel containing from three to ten per cent.
molybdenum, a high speed steel is produced having all the qualities of molybdenum steel containing a relatively large per cent. of molybdenum, and thatthe uranium gives to the product greater efficiency, hardness, toughness, thermal absorption, less brittleness, superior cutting quality and replaces a portion of the molybdenum ordinarily employed. An even smaller proportion of speed steel, I may employ either ferro- 'uranium than three per cent. may be used Q uranium or uranlum metal, which should be added to the bath of molten steel from five to ten minutes before pouring after deslagging and afterj'all other alloys have been added. The steel should be poured as soon as the uranium has become melted,this usually requiring from five to ten minutes unless an electric furnace be employed rather than a crucible when less time will be required for the melting of the uranium.
The presence of uranium in molybdenum steel, not only greatly reduces the proportion of molybdenum necessary, thus reducing the cost of molybdenum content and cost of manufacture of the high speed steel, but it .also enhances the hardness, toughness, thermal absorption and general e ciency and durability of the product for the manufacture of cuttingtools.
The alloy may be crushed to thedesired size and applied to the molten mass while pouring in.the ladle, or after the moltenmass is in the ladle. It may also be applied in the crucible or furnace.
Havin fully described my invention what I'c aim as new and desire to secure by Letters-Patent, is
1. High speed molybdenum steel having uranium alloyed therewith, the uranium replacin a. portion of the molybdenum used in ordinary molybdenum steel.
2. High speed steel containing molybde num and uranium in a proximately the relative proportions speci ed. 3. High speed molybdenum steel having uranium alloyed therewith in proportion less than the lproportion of the molybdenum content, t
e uranium replacing a p01- -tion of the molybdenum used in ordinary ing fromthlee to ten pet-cent. molybdenum 10 molybdenum steel. and approximately three perxc ent. uranium. 4. High speed molybdenum steel .having' In testimony whereof, I have signed this uranium alloyed therewith in a. -proportion specifioation in the presence of two suhscrib- 5 as high as threeper; cent. uranium as a, ing Witnesses.
maximum, the uranium replacing a. portion JOSEPH MICHAEL FLANNIIRY. 'of the molybdenum used in ordinary molyb- Witnessesi j denum steel. WM. GANLEY,
