Divided and this application March 2, 1940, Serial No. 321,910. In Germany March 31, 1937 a high speed'turning tool of a steel containing 2 Claims. The present invention relates to steels intended for the manufacture of high speed machining tools this application being a division of our application Serial No. 192,288. According to the invention such tools are made of steel alloys which contain from 1.0 to 1.6% carbon, from 1.0
to 6.0% chromium, more than 1.0% andless than 5.0% molybdenum, from 2.0 to 6.0% vanadium and tungsten in a quantity amounting to at least 50% of the molybdenum content and ranging from 1.0 to 4.0%, the remainder sub- :laantially all being iron with the normal impuri- Steels of acomposition as specified hereinbeforealthough they containonly small percentages of alloying constituents are distinguished by a high efficiency in the chip-removing. working of materials and can be equal in this respect even to the known high alloy high speed tungsten steels or, under favorable cutting conditions, even be superior to them. Further, steels according to the invention are of a greater efliciency than 1.35% carbon, 4.03% chromium, 3.18% molybdenum, 4.83% vanadium, and 3.06% tungsten at a cutting speed of 13 m. per min. shows a time up to re-grinding of about 59 min. ar'1d at a cutting speed of 14 111. per min. a re-grinding time of 48 min.
The ratio of efllciency to degree of alloying is most favorable with steels according to the invention, which besides iron with the normal lmum and tungsten from 1.0 to 4.0%,-as stated above. 1
What we claim and desire to secure by Let- I ters Patent is:
high speed steels of a similar composition but containing no tungsten at all. Sofor instance a turning tool manufactured from a high speed steel containing 1.35% carbon, 4.27% chromium, 3.25% molybdenum, and 4.69% vanadium, shows in turning chromium-nickel steel of a strength of 100 kg./mm. with a feed of 1.4 mm. and a depth of cut of 5.0 mm., a time up to re-grinding of about 32 min. at a cutting speed of 13 m. per
min., and a time up to re-grinding of about 24 min. at a cutting speed of 14m. per min., whilst 1. A high speed steel consisting of 1.0 to 1.6% carbon, 1.0 to 6.0% chromium, more than 1.0%
and less than 5.0% molybdenum, 2.0. to 6.0%
vanadium and tungsten in a quantity amounting at least to 50% of the molybdenum content and ranging from 1.0 to 4.0%, remainder substantially all iron with the normal impurities.
2. A high speed steel consisting of 1.2 to 1.5%
. carbon, 3.0 to 5.0% chromium, at least 3.0% and less than 5.0% molybdenum, 4.0 to 6.0% vanadi-' um and tungsten in a quantity amounting at least to of the molybdenum content and ranging from 1.0 to 4.0%, remainder substantially all iron with the normal impurities.
