Abstract

Zastosowanie wysokochromowego żeliwa o składzie w granicach C = (1,0 - 1,8%) i Cr = (29 - 36%) udziału masowego, w którym wraz ze wzrostem udziału węgla wzrasta udział chromu, przy czym relacje masowe obu tych pierwiastków mieszczą się w przedziale C/Cr = 0,027 - 0,053, na odlewy nierdzewnych kul do zaworów.The use of high-chromium cast iron with a composition within the limits C = (1.0 - 1.8%) and Cr = (29 - 36%) of the mass share, in which the proportion of chromium increases with the increase of carbon, while the mass relations of both these elements contain in the range C / Cr = 0.027 - 0.053, for casting stainless balls for valves.
