An Example in Steel Casting    Traction Motor Rotor Disc

Alloy Selection

A fundamental design decision is the selection of a steel alloy that meets the performance requirements and has optimal fluidity in the mold.

  • The range of section thicknesses in this casting require that the alloy have excellent fluidity.  

  • Thin sections may not fill well with steel alloys with low fluidity.

And the alloy should have low manganese, phosphorus, and sulfur content to minimize the magnetic hysteresis losses.
