Structure and properties of high-chromium white cast irons

  • 88 Accesses

Conclusions

  1. 1.

    The highly alloyed austenite produced in the alloys investigated, especially alloys 2 and 3, is very stable. The amount of austenite can be reduced only by combined heat treatment.

  2. 2.

    The optimal quenching temperature for all the alloys investigated is in the range of 900–975°.

  3. 3.

    After quenching, all the alloys should be tempered at 450–550°, which produces a hardness above HRC 60 and increases the resistance to abrasive wear.
