| Abstract |
The strength and fatigue crack growth resistance (FCGR) of ferritic, pearlitic and
austenitic nodular cast irons (NCIs), recommended to be used in structural components working at
low (up to –60 °C), cryogenic (below –60 °C) and elevated (450 °C) temperatures, are analysed.
The influence of the manganese content and the strain-induced martensite transformation on FCGR
of the austenitic NCIs is shown. An admissible phosphorus content for the optimum wear resistance
and FCGR is determined. The strength and FCGR of the NCIs and corresponding rolled steels are
compared. |
