Abstract
Highly-stressed machine parts and work pieces having a wall thickness or cross-section exceeding 300 mm., are prepared from a steel having a carbon content of less than 0,18 per cent, preferably less than 0,14 per cent and containing 1-8 per cent of chromium, 0,1-1,5 per cent of vanadium, 0,05-5 per cent of nickel, and 0,1-1,5 per cent of molybdenum, and are then heat treated to produce hardening. The steel may also contain up to 2 per cent of manganese or silicon or both and the molybdenum may be replaced wholly or in part by 0,15-7 per cent of tungsten. The heat treatment may consist in quenching in water or oil, followed by tempering at 600 DEG C. The Specification as open to inspection under Sect. 91 comprises also the use of steels containing one or more of the above alloying ingredients, some of which may be present in differing proportions, the nickel being replaceable wholly or in part by up to 5 per cent of copper. This subject-matter does not appear in the Specification as accepted.
