UNITED STATES PATENT OFFICE.
WALTER LOTH AR EDUABD EILENDER, OF REMSCHEID, GERMANY, ASSIGNOB, BY MESNE ASSIGNMENTS, TO THE CHEMICAL FOUNDATION, INC., A CORPORATION OF DELAWARE.
HIGH-SPEED STEEL.
No Drawing.
To all whom it may concern:
Be it known that I, WALTER LOTHAR EDU- ARD EILENDER, a subject of the German Emperor, and residing at Remscheid, Germany, have invented certain new and useful Improvements in High-Speed Steels Free from Tungsten for Average Cutting Capacity, of which the following is a specification.
This invention relates to improvements in steel alloys especially useful for cutting tools, known as high speed tool steel, and aims to provide improvements therein.
The invention provides a tool steel which can be made without the use of tungsten.
The tool steel of my invention has the following composition 7 Carbon .5.8 per centum. Manganese 2-.4 i f Silicon 2-.4 Molybdenum 6.10. I Chromium 3.-6.
The tool steel having the foregoing com- Specification of Letters Patent.
Patented Apr. 20, 1920.
Application filed March 6, 1917. Serial No. 152,724.
well known high speed steel with- 12-17 per cent. of tungsten.
The steel may be produced by melting, in crucibles, bar steel containing the required content of carbon, manganese, and silicon, and adding thereto the requisite amount of the metals molybdenum and chromium, viz., 6 to 10 per cent. molybdenumand3to 6 per cent. chromium, and after proper fusion the melted metal is poured from the crucibles into suitable ingot molds, from which it is obtained in the form of ingots.
What is claimed is A steel-alloy for use as high speed steel of an average cutting-capacity consisting of iron and 0.5-0.8 p. c. C, 0.2-0.4 p. 0. Mn,
I 0.2-0.4 p. 0. Si, 6.0-10.0 p. e. Mo. and 3.0-6.0
0. Cr. p In testiinontyl whereof I hereunto afiix my signature in t e presence of two witnesses.
W WALTER EDUABD EILENDER.
