die casting molds are subjected to repeated heating and cooling during production of aluminum castings. what are two properties of h13 steel that would make it a good material for use as a die casting mold.

Answer

Brief Explanations:

  • Thermal conductivity: High thermal conductivity allows for efficient heat transfer, which is crucial for rapid heating and cooling cycles in die - casting. This helps in maintaining consistent casting quality and reducing cycle times.
  • Thermal fatigue resistance: Die - casting molds undergo repeated heating and cooling (thermal cycling). H13 steel has good thermal fatigue resistance, meaning it can withstand many cycles of expansion (due to heating) and contraction (due to cooling) without cracking or failing prematurely.

Answer:

Thermal conductivity and thermal fatigue resistance.
