Tyrax ESR Steel

Tyrax ESR Steel

Steel name: Tyrax ESR
Diagram No.: 2765
Chemical composition in weight %: 0.40% C, 0.20% Si, 0.50% Mn, 12.00% Cr, 0.50% V, +N
Steel group: Plastic mould steels
Properties: Uddeholm Tyrax ESR is a premium high hardness and corrosion resistant plastic mould steel.
Applications: Uddeholm Tyrax ESR is suitable for long run production moulds, moulds for reinforced plastics and for compression moulding. Engineering applications like plasticizing screws are also an option. Uddeholm Tyrax ESR can be used in corrosive conditions as moulds subjected to humid working/storage conditions or for production of corrosive plastics. Its high toughness/ductility makes it suitable for complex moulds. Uddehom Tyrax ESR is also suitable when high gloss surface finish is required.

Heat Treatment
Hardening: Use a preheating temperature of 600-850°C (1110-1560°F). Recommended austenitizing temperature is 1050-1080°C (1920-1975°F), holding time 30 minutes.
Quenching media recommended are: Vacuum furnace (high speed gas with sufficient overpressure). Fluidized bed or salt bath at 250-550°C (480- 1020°F) then cool in air blast. High speed gas/circulating atmosphere.
Tempering: Tempering temperature should be selected depending on aimed hardness according to the graphs shown below. Temper twice with intermediate cooling to room temperature. Lowest tempering temperature is 200 °C. Holding time at tempering is 2h.
Diagram note: The tempering curve is obtained after heat treatment of samples with a size of 15 x 15 x 40 mm, cooling in a vacuum furnace.
