9966 SUPER C Steel

9966 SUPER C Steel

Steel name: 9966 SUPER C
Diagram No.: 2287
Chemical composition in weight %: 0.33% C, 0.25% Si, 0.20% Mn, 0.003% P, 0.002% S, 1.50% Cr, 0.80% Mo, 3.00% Ni, 0.30% V
Steel group: Hot work tool steels
Properties: Patented NiCrMoV-hot work tool steel with good high-temperature strength, (comparable to steels 2343 and 2344), but with much higher toughness. Higher wear-resistance than die steel 2714.
Applications: Dies that are susceptible to fracture, and die inserts with deep impressions, die holders. Crack-susceptible extrusion moulds for aluminium forming. Crack-prone plastic moulds.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: Temperature: 870 °C. Duration: 1 minute per mm wall thickness.
Tempering: Temperature: See tempering curve. Duration: 1 hour per 25 mm wall thickness. Cooling: Air.
Diagram note: Average values on samples dia. 25 x 50 mm long, hardened at 870 °C in oil. HB converted from HRC.
