Steel group: Hot work tool steels
Properties: Uddeholm Vidar 1 ESR is a chromium-molybdenum- vanadium-alloyed steel
Applications: General hot work and plastic mould applications, specially large plastic moulds with requirements on high toughness in combination with very good polishability and texturing properties.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: Preheating temperature: 600–850°C (1112– 1562°F) (normally two preheating steps). Austenitizing temperature: 990–1010°C (1814– 1850°F), normally 990–1000°C (1814–1832°F). Soaking time: 30–45 minutes. Soaking time = time at austenitizing temperature after the tool is fully heated through.
Quenching media: High speed gas/circulating atmosphere. Vacuum (high speed gas with sufficient positive pressure). Martempering bath (salt or fluidized bed) at 500–550°C (932–1022°F). Martempering bath (salt or fluidized bed) at 180–220°C (356–428°F). Warm oil.
Tempering: Choose the tempering temperature according to the hardness required by reference to the tempering graph below. Temper twice with intermediate cooling to room temperature. Lowest tempering temperature 180°C (356°F). Holding time at temperature minimum 2 hours. Tempering in the range of 425–550°C (797– 1022°F) for the intended final hardness will result in a lower toughness.
