Material Properties

  • Corrosion resistance is very high.
  • It has a good taste.
  • It is pre-hardened but easy to process (due to S contribution).
  • It has optimum abrasion resistance.
  • It is not suitable for nitration process.

Applications

  • Extrusion and injection molds of corrosive polymers such as PVC,
  • As mold holder and calibration block,
  • As a mold holder,
  • It is used in machine parts.
