Strength Characteristics


  1. 1.

    After quenching and tempering, the ductility and toughness of tangential samples of forged steel are lower than those of longitudinal smaples at standard temperature; the properties are isotropic in the cast steel.

  2. 2.

    At 600–800°C the strength and ductility of tangential samples are almost identical, while the toughness of the cast steel is considerably higher than that of the forged steel.

  3. 3.

    The greater durability of centrifugally cast molds as compared with forged molds as compared with forged molds is due to the isotropic properties of the cast steel and the smaller quantity of segregated impurities and nonmetallic inclusions in the working surface.

  4. 4.

    The use of centrifugally cast molds in place of forged molds reduces the expenditure of metal ∼40%.
