Uddeholm Tyrax ESR

DESIGNED FOR BEST POLISHABILITY

Uddeholm Tyrax ESR combines best in class toughness, corrosion and wear resistance. This grade was developed for molding of high performance plastics often filled with glass fiber reinforcements and additives like flame retardants. This matrix- based microstructure is designed to achieve a high-gloss surface by only a few polishing steps, dramatically reducing the tool lead time and enabling production of top quality plastic parts. Uddeholm Tyrax ESR can achieve a high hardness ( up to 58 HRC) and is a suitable upgrade from AISI 420 ESR, AISI S7 & AISI 440C.

  • Good corrosion resistance.
  • High hardness (Up to 60 HRC, recommended hardness: 55 – 58 HRC).
