The present invention relates to steels intended for the manufacture of high speed machining tools, this application being a division of our Patent No. 2,159,086. According to the inven- 5 tion such tools are. made of steel alloys which contain from 0.6 to 1.0% carbon, from 1.0 to
6.0% chromium, from- 1.0 to 76.0% molybdenum; from 1.0 to 3.0% vanadium and tungsten in a quantity amounting at least to 50% of the molybdenum content and ranging from. 1.0 to 4.0%.
the remainder substantially all iron with the normalimpurities. v
Steels of a composition as specified herelnbefore although they contain only small percentagesof alloying constituents are distinguished by a high efilciencyin the chip-removing working of materials and can be equal in this respect even to the high alloy high speed tungsten steels or, under favorable cutting conditions. even be a superior to them. The best results are obtained,
by steels which contain the alloying constituents within the following-limits:
(0!. 75-126) "0.6 to.1.0%, chromium from 3.0' to 6.0%, mo-
less than 5.0% molybdenum, 1.0-3.0% vanadium,
and tungsten in a quantity amounting at'least to of the molybdenum content and ranging from 1.0-4.0%, remainder substantially all iron with the normal impurities.
v 2. High speed steels composed of 0.6-1.0% carbon, 3.0-6.0%- chromium, 2.0 to 4.0% molybdenum, 204.0% vanadium and tungsten in a quantity amounting at least to 50% of the molybdenum content and ranging remainder substantially all iron with the normal impurities. v
