Abstract (en)
[origin: EP1300482A1] Heat-deviating steel object is made from a composition containing (in wt.%): 0.451-0.598 carbon, 0.11-0.29 silicon, 0.11-0.39 manganese, 4.21-4.98 chromium, 2.81-3.29 molybdenum, 0.41-0.69 vanadium and a balance of iron and impurities. The object has a hardness of at least 58 HRC at an impact bending force of at least 170 J and a notched bar impact work of at least 11 J. <??>Preferred Features: The ratio of the concentration of vanadium to carbon is 0.82-1.38. The ratio of chromium + molybdenum + vanadium is 15.2 to 18.4.
