UNITED STATES PATENT OFFICE.
SAMUEL S. WALES, OF MUNHALL, PENNSYLVANIA. ASSIGNOR TO THE CARNEGIE STEEL COMPANY, OF PITTSBURG, PENNSYLVANIA. A CORPORATION OF NEW Patented Mar. 15, 1910.
JERSEY.
V STEEL ALLOY.
952,392, Specification of Letters Patent.
No Drawing.
T 0 all whom, it may concern:
Be it known that I, SAMUEL S. WALES, of Munhall, Allegheny county, Pennsylvania, have invented a new and useful Improvement in Steel Alloys, of which the followin is a full. clear. and exact description.
.I v invention relates to alloy steels. and more particularly relates to alloy steels used in making armor plates either with or without a carburized face.
The object of my invention is to provide a new alloy which will give a metal of great strength and a high resistance to impact and s we t.
Another object of the invention is to provide an alloy which readily lends itself to subsequent heat treatments generally used in the manufacture of armor plate.
In the alloy steels now used, from 2.50 per ]cent. to 5.00 per cent. nickel is generally use( I have discovered that by the addition of copper to the alloy. within certain limits,
the tensile strength is increased and the reduction in area of the steel is also ncreased. without lessening the physical qualities of the alloy.
In carrying out my process. the following proportions have been found to give the desired results:carbou: manganese; nickel,
below 4.00 per cent; chromium, below 2.00 per cent.: vanadium. .10 per cent. to .50 per cent: copper. less than 1.00 per cent.
The addition of the copper within the limits named increases the tensile strength Application filed. December 27, 1909. Serial No. 584,984.
than .04 er cent., and the phosphorus content shou d be very low.
The advantages of m invention will be apparent to those skille in the art.
By the addition of a small amount of copper, which is comparatively cheap. new and characteristic phvsical properties are imparted to the steel.
Changes in the proportions of the various alloying metals within the usual variations found in carrying out the making of steel may be made without departing from my invention.
I claim 1. An alloy steel containing manganese. up to 4.00 per cent. nickel, below 2.00 per cent. chromium. up to .50 per cent. vanadium and u to 1.00 per cent. copper.
2. 'n alloy steel containing below -1.00 per cent. nickel, less than .50 per cent. vanadium and up to 1.00 per cent. co )per.
3. An alloy steel containing nicke chromium below 2.00 per cent, up to .50 per cent. vanadium and less than 1.00 per cent.
copper. V
4. An alloy steel containing nickel up to 4.00 per cent, chromium from 1.00per cent. to 2.00 1' cent, vanadium up to .50 per cent. an copper up to 1.00 per cent.
5. An alloy steel containin manganese, less than 4.00 per cent. nickel, c lromium, up to .50 per cent. vanadium and up to 1.00 per cent. copper. i
In testimony whereof, I have hereunto set my hand.
