This invention relates to manufacture of steel, its object bein to provide a substitute form-high speed steel of a composition par-' ticfularly suitable for making cutting tools dies and parts subjected to great abrasive wear by alloying together a mixture of a. small quantity of tungsten, nickel andtl- :tanium with a high percentage chromiumcarbon steel. I have made several tests ofvarious compositions of high chromiumcarbon steels such as are manufactured to resist abrasive wear for such purposes as pulverizing machinery parts, burglar-proof safe plate, steam-shovel pins, dipper teeth etc. which because of its extreme hardness also can be used for edge tools with far more eiliciency than ordinary tool steel, and greatly improved by addition .of a small amount of tungsten and will keep a {very fine keen edge while cutting at high speeds.
Heretofore, standard grades of high speed steel which contain more or less of these same ingredients especially a high percentage of tungsten have been designed and used for fast cutting and milling tools, etc. and its use is almost entirely limited to lathe,
laner, boring, milling and similar cutters or rough machining operations and the chine operation, using high carbon tool steel cutters or special oil hardening steel cutters to give the necessary fine smooth finish to the work and this must be done at a very low speedto preserve the keen edge on these finishing cutters.
As a result of m experiments I have found that a good substitute for high speed steel can be made containing comparatively high percentages. of carbon and chromium, from 2 percent to 8 percent tungsten and a all amount of nickel and titanium, this composition after casting or machining to desired shape also sponding to hardening treatment at a conslderably lower heat than is required for high tungsten steels thereby preserving the fine edges and surface of intricate shaped tools, dies etc. I
