Based on YTR5(H13), EAST TOOL developed YTR18 as a high quality high grade substitute to it.

Property:

  • YTR18 has excellent toughness and thermal conductivity, and is good resistant to softening during tempering.
  • YTR18 has better high-temperature flexibility and ability to resist thermal fatigue.
  • Processed through Electro Slag Remelting (ESR), YTR18 has excellent toughness and ductility in all directions.
  • Workable hardness is HRC 46-52.

Application:

  • Aluminum and Magnesium pressure-casting Die.
  • Copper alloy extrusion Die.
  • Also suitable for high-grade plastic moulds.

Steel density 7.86g / cm3
